Is a mobile first game engine.
Everything this engine does is with mobile devices in mind.
This means that you won’t find a hover state on buttons as that is something only desktop devices are capable of. The aim here is to offer a simple API for games that can be ported directly to all major mobile platforms without any trouble along the way using Apache Cordova or other build tools.
If your goal is to build a simple game and don't want to deal with problems tied to development without a framework.
If you think that other solutions like Phaser.js are too heavyweight solutions for your game.
If you are looking for API reference then the official documentation is at your disposal.
If you want to help with getting started and are new to creating games, then have a look at the official tutorial here.
For those already familiar with the basic concepts of JavaScript based games could benefit more from live examples, which can be found here.

As we move our businesses to the cloud, we need to work smarter, as security data is spread across cloud and on-premises environments, exposing gaps and vulnerabilities. Accordingly, we need AI-enabled approaches for security to help organizations gain deeper insights, mitigate risks and accelerate the response. With an open security platform that can advance an organization's zero-trust strategy, you can use your existing investments while leaving your data where it is — helping your team become more efficient and collaborative. Accordingly, security and risk management (SRM) leaders are being driven to reduce technology complexity, essentially being tasked to "do more with less". To accomplish this, as well as to keep up with the ever-changing threat landscape, organizations are working towards adopting consolidated AI-enabled security platforms.
The challenges in this hackathon will focus on novel applications of AI in security, from machine learning and data analytics to cognitive assistants. The goal is to leverage AI to stay ahead of threats and learn how to respond w/ greater confidence and speed.

The first model is a full body scan of a male, minus the head and feet. We can't show the model's head or you'd be able to identify the person. None of our models contain obvious features that would allow you to identify the person.
This model is interesting because you can clearly see the body hair that covers most of the model. Hair poses difficulties in the process of making models and we required that our models shave completely, otherwise the models would be impossible to create.
If you click on the image you'll be taken to a page where you can twirl, pinch and zoom the model to investigate every detail of the model. Click on it and see if you can zoom in and look under the testicles!
This full body model of a female is quite different from the first model -- you can clearly see that this model has no body hair. If you take a look at her breasts you'll notice that one nipple is pierced and that her breasts are different sizes. This is very common -- humans are not usually perfectly symmetrical.
If you click on the model and spin it around and look underneath her buttocks you can see a line of triangles in the fold between her buttocks and her legs. This line is an artifact of the 3D model -- as much as we would like to show perfect models, they would simply be too large to be viewed on a mobile phone. In order to make this site accessible to everyone, we worked hard to keep the models small so that they can be viewed even on the simplest smartphones.

You can also see that the testicles appear to be large in relation to the size of the penis. This is accentuated by the pose (lying) and appears less noticable in models of males who are standing.
In this model as well, you can see some artifacts if you view the testicles from the bottom. If you decide to 3D print this model, you will download a much higher resolution version and these artifacts will not appear.
The first vulva model shows a female who is lying down and her labia have been arranged. Arrangement is a tricky concept -- any time that the model was prepared, or posed, in some way we describe that as arranged. When a model is not arranged in any way, we describe it as natural.
You should also notice that the labia minora (the inner labia) are asymmetric -- this is also quite common. And the labia majora are almost not perceptible in this model.
Please note that we don't call these models vaginas, since the vagina is not really visible here. For more details on this, as well as an explanation for labia minora/majora please see our illustrated guide to human sexuality.
This model of breasts is from a standing female. Here too, the breasts are also ever so slightly different sizes and the nipples are quite pronounced.
Nipples are another human feature that vary greatly from human to human!
Also note how the skin is quite smooth, with no hair, and free of any blemishes.
This buttocks model is of a standing male.
We are pleased with this model -- it came out very well with very few visible flaws.
A previous version of this model had an elongated rectangular artifact above the right buttock -- this was our scanning tag -- effectively a ruler on a sticker that all of our models are required to wear during the photo shoot. This ruler gives us the necessary information on how to scale the model so that we can ensure that the model is an accurate size.
This lower body model is of a standing male.
In this model you can also see that the model has body hair and an uncircumsized penis.
We hope that this first exhibit has given you a gentle introduction to our project and the various types of models that we've collected. We tried to highlight the various features of each model, and most importantly that none of these models are perfect. With humans there is no perfect -- every human is distinct -- and we are all beautiful!

To build executables in Elixir we will be using escript. Escript produces an executable that can be run on any system with Erlang installed.
Table of Contents
Getting Started
To create an executable with escript there are only a few things we need to do: implement a main/1
function and update our Mixfile.
We’ll start by creating a module to serve as the entry point to our executable.
This is where we’ll implement main/1
:
defmodule ExampleApp.CLI do
def main(args \\ []) do
# Do stuff
end
end
Next we need to update our Mixfile to include the :escript
option for our project along with specifying our :main_module
:
defmodule ExampleApp.Mixfile do
def project do
[app: :example_app, version: "0.0.1", escript: escript()]
end
defp escript do
[main_module: ExampleApp.CLI]
end
end
Parsing Args
With our application set up we can move on to parsing the command line arguments.
To do this we’ll use Elixir’s OptionParser.parse/2
with the :switches
option to indicate that our flag is boolean:
defmodule ExampleApp.CLI do
def main(args \\ []) do
args
|> parse_args()
|> response()
|> IO.puts()
end
defp parse_args(args) do
{opts, word, _} =
args
|> OptionParser.parse(switches: [upcase: :boolean])
{opts, List.to_string(word)}
end
defp response({opts, word}) do
if opts[:upcase], do: String.upcase(word), else: word
end
end
Building
Once we’ve finished configuring our application to use escript, building our executable is a breeze with Mix:
$ mix escript.build
Let’s take it for a spin:
$ ./example_app --upcase Hello
HELLO
$ ./example_app Hi
Hi
That’s it. We’ve built our first executable in Elixir using escript.

Our project aims to develop a DNA hydrogel system which can target, capture and isolate circulating tumor cells (CTCs). Once the DNA aptamers target the CTCs, it will trigger the rolling circle amplification (RCA, or R) followed by a multi-primed chain amplification (MCA, or M). The amplified DNA fragments will form a network of hydrogen to capture the CTCs. This structure enlarges the size of CTCs and help to separate them. Moreover, this separating process can be seen because of the fluorophore attached to the DNA template.
Team DUT China A attaches great importance to the safety and security
of both scientists and the environment. Our host lab, Zi Laboratories,
follows General requirements for laboratory biosafety in China.
Although all the members involved in the experiment were trained
strictly before thanks to their professional course, our professional
experimental teachers still helped us to conduct systematic
experimental safety training right before the lab work start. The
consultant, who has extensive experience in genetic engineering and
has been doing research on the circulating tumor cells for many years,
helped us to understand the experimental procedures and attentions for
the experiments relating to cells. Throughout the project, we reported
the progress to our directors and got instructions from them every
week.
We strictly obey the rules of the laboratory practices and guidelines.
All our reagents and instruments have their own fixed position,
strictly comply with the drug label management regulations. Everyone
doing the experiment should wear experimental gloves and safety
goggles and do not take them out of the lab. We close UV light after
sterilization of our clean bench and then perform operations under
white light. Before performing the experiment operation around the
flame lamp in the cleaning bench, we use the 75% alcohol spray to
clean our hands and wait for them to be air-dried. Moreover, all the
toxic reagents are used according to their instruction. Sharp objects
such as broken glass are placed separately from other items. After the
experiment is completed, we sterilize the experimental equipment and
place the experimental in a special garbage bag and hand over to the
biological waste professional processing company. All the methods
above are to ensure the safety and security of the laboratory and to
avoid the environmental pollution of the experimental organisms.

Chapter 13. Complexity: As Simple As Possible, but No Simpler
At the end of Chapter 1, we summarized the Unix philosophy as "Keep It Simple, Stupid!" Throughout the Design section, one of the continuing themes has been the importance of keeping designs and implementations as simple as possible. But what is "as simple as possible"? How do you tell? We've held off on addressing this question until now because understanding simplicity is complicated. It needs some of the ideas we developed earlier in the Design section, especially in Chapter 4 and Chapter 11, as background. The large questions in this chapter are central preoccupations of the Unix tradition, some of them motivating holy wars that have simmered for decades. This chapter starts from established Unix practice and vocabulary, then goes a bit further beyond it than we do in the rest of the book. We don't try to develop simple answers to these questions, because there aren't any—but we can hope that you will walk away with better conceptual tools for developing your own answers. |

Key Assumption Check
This scheme asserts that an unsupported CLAIM in an argument map is an assumption that must be justified. The QUALIFIER is presumably. The DATA for the scheme is an unstated premise (which is incidentally itself an assumption) that implies that CLAIM is presumably a valid assumption.
The critical questions are:
-
How confident are you that this assumption is correct? What explains your degree of confidence?
-
What circumstances or information might undermine this assumption?
-
Could this assumption have been true in the past, but less so now?
The scheme has no WARRANT and hence no BACKING. The only possible rebuttal is an assertion that CLAIM is an invalid assumption.
Notes
Evaluation of this scheme gives just one extension, where the critical questions are acceptable and CLAIM is unacceptable (an invalid assumption). The assumption can only be made valid by "answering" each of the critical questions with an argument that undermines or undercuts it. If all questions are answered, then there is no attack on the inference that CLAIM is a valid assumption, and the scheme evaluates to a single extension with CLAIM skeptically acceptable.
The critical questions under the first bullet point form a coordinative argument. This argument can be defeated by answering either question.

MSPriorityQueue traits.
Storage type.
The storage type for the heap array. Default is cds::opt::v::initialized_dynamic_buffer
.
You may specify any type of buffer's value since at instantiation time the buffer::rebind
member metafunction is called to change type of values stored in the buffer.
Priority compare functor.
No default functor is provided. If the option is not specified, the less
is used.
Specifies binary predicate used for priority comparing.
Default is std::less<T>
.
Internal statistics.
Possible types: mspriority_queue::empty_stat
(the default, no overhead), mspriority_queue::stat
or any other with interface like mspriority_queue::stat

I currently work here!
• 2017 Pricing
Due to changing requirements of the 2017 Pricing, I believe we have solutioned the most flexible
pricing service (it just reads from a YML file).
• DevOps
We had an 11 step process for deployment with multiple points of failure. We have brought it down
to 2-click-deployment process.
This is the main project at Brewhouse where I got hired as an apprentice and grew my skills to be a Junior Developer. I've helped in various areas of the app, such as: Content Library, 2016 Pricing, Link Shortener & Sharing Banner
The hardest part about building the MVP of Pixhug was the ask that the likes should be polled and it should be realtime or close to it. We had to create a service that will poll Facebook for likes as much as it could without getting rate limited. Maybe I'll write a blogpost on how we solved this problem.
The initial ask at Attendease was to migrate their database from MongoDB to PostgresQL but with the current state of the app at that time, we had to bring the test coverage up (using simplecov) and slowly change the syntax from a Mongo query to a SQL query.
I came to the avenue spaces towards the middle of creating it's MVP while being an apprentice at Brewhouse. Our lead designer created pixel perfect images that I had to copy with CSS. I've helped create the questionaire and added functionalities to their admin portal.

Description
----
The `rms-spark-barchart` web component renders four distinct bar chart types, as per the `chartType` attribute:
1. `positive`: Positive charts' bars with positve heights are drawn northward; bars with negative heights are cropped out.
1. `negative`: Negative charts' bars with negative heights are drawn southward; bars with positive heights are cropped out.
1. `dual`: Dual charts' bars heights are negative, zero, or positive, with a positive height bars drawn northward and negative ones southward.
1. `tri`: Tri charts have negative, zero, and positive bars. The positive and negative bars are half of the box height, whereas the aero bar is one fouth of it. Negative bara are drawn sothward, zeros stradding the x-axis, and positives northward.
### Usage

| modelMatrix-class {MatrixModels} | R Documentation |
The class "modelMatrix"
and notably its subclass
"dsparseModelMatrix"
are used to encode additional information,
analogously to what the standard R function
model.matrix()
returns.
Only "dsparseModelMatrix"
and "ddenseModelMatrix"
are
“actual” (aka non-virtual) classes. For these,
objects can be created by calls of the form
new("dsparseModelMatrix", x, assign, contrast)
, where x
is a dgCMatrix
classed object.
The "modelMatrix"
mother class contains
Matrix
plus two extra slots,
assign
:"integer"
vector of length
ncol(.)
, coding the variables which make up the
matrix columns, see model.matrix
.
contrasts
:a named list
of
contrasts
, as in model.matrix()
.
Dim
:integer vector of length two with the matrix dimensions.
Dimnames
:list of length two, the
dimnames(.)
of the matrix.
whereas the (current only) actual classes "d*ModelMatrix"
,
have an at least an additional (numeric
slot "x"
.
E.g., "dsparseModelMatrix" has the additional slots
i
,p
:row number and “pointer” integer
vectors, see class "dgCMatrix"
.
x
:"numeric"
vector of non-zero entries.
factors
:a (possibly empty) list
of
factorizations.
"dsparseModelMatrix"
extends class "dgCMatrix"
directly,
"ddenseModelMatrix"
extends class "dgeMatrix"
directly.
signature(object = "modelMatrix")
:
show(.)
the matrix, but also the assign
and
contrasts
slots.
signature(x = "modelMatrix")
: as show()

) allowing to pass further arguments for
printing the matrix.
Martin Maechler
sparse.model.matrix
will return a
"dsparseModelMatrix"
object.
model.Matrix
which is a simple wrapper around the traditional
model.matrix
and returns a "ddenseModelMatrix"
object.

The name of this class derives from the fact that we originally implemented it as a layer on top of the "pnm library", based on netpbm, which was built to implement pbm, pgm, and pbm files, and is the underlying support of a number of public-domain image file converters.
Nowadays we are no longer derived directly from the pnm library, mainly to allow support of C++ iostreams instead of the C stdio FILE interface.
Conceptually, a PNMImage is a two-dimensional array of xels, which are the PNM-defined generic pixel type. Each xel may have a red, green, and blue component, or (if the image is grayscale) a gray component. The image may be read in, the individual xels manipulated, and written out again, or a black image may be constructed from scratch.
A PNMImage has a color space and a maxval, the combination of which defines how a floating-point linear color value is encoded as an integer value in memory. The functions ending in _val operate on encoded colors, whereas the regular ones work with linear floating-point values. All operations are color space correct unless otherwise specified.
The image is of size XSize() by YSize() xels, numbered from top to bottom, left to right, beginning at zero.
Files can be specified by filename, or by an iostream pointer. The filename "-" refers to stdin or stdout.
This class is not inherently thread-safe; use it from a single thread or protect access using a mutex.

| addAlpha | ( | ) |
Adds an alpha channel to the image, if it does not already have one.
The alpha channel is initialized to zeros.
| addSubImage | ( | const PNMImage | copy, |
| int | xto, | ||
| int | yto, | ||
| int | xfrom, | ||
| int | yfrom, | ||
| int | x_size, | ||
| int | y_size, | ||
| float | pixel_scale | ||
| ) |
Behaves like copy_sub_image(), except the copy pixels are added to the pixels of the destination, after scaling by the specified pixel_scale.
Unlike blend_sub_image(), the alpha channel is not treated specially.
| alphaFill | ( | float | alpha | ) |
Sets the entire alpha channel to the given level.
| alphaFillVal | ( | Xelval | alpha | ) |
Sets the entire alpha channel to the given level.
| applyExponent | ( | float | gray_exponent | ) |
Adjusts each channel of the image by raising the corresponding component value to the indicated exponent, such that L' = L ^ exponent.
| applyExponent | ( | float | gray_exponent, |
| float | alpha_exponent | ||
| ) |
Adjusts each channel of the image by raising the corresponding component value to the indicated exponent, such that L' = L ^ exponent.
| applyExponent | ( | float | red_exponent, |
| float | green_exponent, | ||
| float | blue_exponent | ||
| ) |
Adjusts each channel of the image by raising the corresponding component value to the indicated exponent, such that L' = L ^ exponent.
For a grayscale image, the blue_exponent value is used for the grayscale value, and red_exponent and green_exponent are unused.
| applyExponent | ( | float | red_exponent, |
| float | green_exponent, | ||
| float | blue_exponent, | ||
| float | alpha_exponent | ||
| ) |
Adjusts each channel of the image by raising the corresponding component value to the indicated exponent, such that L' = L ^ exponent.
For a grayscale image, the blue_exponent value is used for the grayscale value, and red_exponent and green_exponent are unused.
| blend | ( | int | x, |
| int | y, | ||
| const LRGBColorf | val, | ||
| float | alpha | ||
| ) |
Smoothly blends the indicated pixel value in with whatever was already in the image, based on the given alpha value.
An alpha of 1.0 is fully opaque and completely replaces whatever was there previously; alpha of 0.0 is fully transparent and does nothing.
| blend | ( | int | x, |
| int | y, | ||
| float | r, | ||
| float | g, | ||
| float | b, | ||
| float | alpha | ||
| ) |
Smoothly blends the indicated pixel value in with whatever was already in the image, based on the given alpha value.
An alpha of 1.0 is fully opaque and completely replaces whatever was there previously; alpha of 0.0 is fully transparent and does nothing.
| blendSubImage | ( | const PNMImage | copy, |
| int | xto, | ||
| int | yto, | ||
| int | xfrom, | ||
| int | yfrom, | ||
| int | x_size, | ||
| int | y_size, | ||
| float | pixel_scale | ||
| ) |
Behaves like copy_sub_image(), except the alpha channel of the copy is used to blend the copy into the destination image, instead of overwriting pixels unconditionally.
If pixel_scale is not 1.0, it specifies an amount to scale each alpha value of the source image before applying it to the target image.
If pixel_scale is 1.0 and the copy has no alpha channel, this degenerates into copy_sub_image().
| boxFilter | ( | float | radius | ) |
This flavor of box_filter() will apply the filter over the entire image without resizing or copying; the effect is that of a blur operation.
| boxFilterFrom | ( | float | radius, |
| const PNMImage | copy | ||
| ) |
Makes a resized copy of the indicated image into this one using the indicated filter.
The image to be copied is squashed and stretched to match the dimensions of the current image, applying the appropriate filter to perform the stretching.
| Xelval clampVal | ( | int | input_value | ) |
A handy function to clamp values to [0..get_maxval()].
| clear | ( | ) |
Frees all memory allocated for the image, and clears all its parameters (size, color, type, etc).
| clear | ( | int | x_size, |
| int | y_size, | ||
| int | num_channels, | ||
| Xelval | maxval, | ||
| PNMFileType | type, | ||
| ColorSpace | color_space | ||
| ) |
This flavor of clear() reinitializes the image to an empty (black) image with the given dimensions.

| copyChannel | ( | const PNMImage | copy, |
| int | src_channel, | ||
| int | dest_channel | ||
| ) |

Images must be the same size
| copyChannel | ( | const PNMImage | copy, |
| int | xto, | ||
| int | yto, | ||
| int | cto, | ||
| int | xfrom, | ||
| int | yfrom, | ||
| int | cfrom, | ||
| int | x_size, | ||
| int | y_size | ||
| ) |
Copies just a single channel from the source image into a single channel of this image, leaving the remaining channels alone.
| copyChannelBits | ( | const PNMImage | copy, |
| int | src_channel, | ||
| int | dest_channel, | ||
| Xelval | src_mask, | ||
| int | right_shift | ||
| ) |
Copies some subset of the bits of the specified channel from one image into some subset of the bits of the specified channel in another image.
Images must be the same size.
If right_shift is negative, it means a left shift.
| copyFrom | ( | const PNMImage | copy | ) |
Makes this image become a copy of the other image.
| copyHeaderFrom | ( | const PNMImageHeader | header | ) |
Copies just the header information into this image.
This will blow away any image data stored in the image. The new image data will be allocated, but left unitialized.
| copySubImage | ( | const PNMImage | copy, |
| int | xto, | ||
| int | yto, | ||
| int | xfrom, | ||
| int | yfrom, | ||
| int | x_size, | ||
| int | y_size | ||
| ) |
Copies a rectangular area of another image into a rectangular area of this image.
Both images must already have been initialized. The upper-left corner of the region in both images is specified, and the size of the area; if the size is omitted, it defaults to the entire other image, or the largest piece that will fit.
| darkenSubImage | ( | const PNMImage | copy, |
| int | xto, | ||
| int | yto, | ||
| int | xfrom, | ||
| int | yfrom, | ||
| int | x_size, | ||
| int | y_size, | ||
| float | pixel_scale | ||
| ) |
Behaves like copy_sub_image(), but the resulting color will be the darker of the source and destination colors at each pixel (and at each R, G, B, A component value).
If pixel_scale is not 1.0, it specifies an amount to scale each pixel value of the source image before applying it to the target image. The scale is applied with the center at 1.0: scaling the pixel value smaller brings it closer to 1.0.
| doFillDistance | ( | int | xi, |
| int | yi, | ||
| int | d | ||
| ) |
Recursively fills in the minimum distance measured from a certain set of points into the gray channel.

| int | right, | ||
| int | bottom, | ||
| int | top, | ||
| const LColorf | color | ||
| ) |

The new pixels are set to the indicated color.
If any of the values is negative, this actually crops the image.
| fill | ( | float | gray | ) |
Sets the entire image (except the alpha channel) to the given grayscale level.
| fill | ( | float | red, |
| float | green, | ||
| float | blue | ||
| ) |
Sets the entire image (except the alpha channel) to the given color.
| fillDistanceInside | ( | const PNMImage | mask, |
| float | threshold, | ||
| int | radius, | ||
| bool | shrink_from_border | ||
| ) |
Replaces this image with a grayscale image whose gray channel represents the linear Manhattan distance from the nearest dark pixel in the given mask image, up to the specified radius value (which also becomes the new maxval).
radius may range from 0 to maxmaxval; smaller values will compute faster. A dark pixel is defined as one whose pixel value is < threshold.
If shrink_from_border is true, then the mask image is considered to be surrounded by a border of dark pixels; otherwise, the border isn't considered.
This can be used, in conjunction with threshold, to shrink a mask image inwards by a certain number of pixels.
The mask image may be the same image as this one, in which case it is destructively modified by this process.
| fillDistanceOutside | ( | const PNMImage | mask, |
| float | threshold, | ||
| int | radius | ||
| ) |
Replaces this image with a grayscale image whose gray channel represents the linear Manhattan distance from the nearest white pixel in the given mask image, up to the specified radius value (which also becomes the new maxval).
radius may range from 0 to maxmaxval; smaller values will compute faster. A white pixel is defined as one whose pixel value is >= threshold.
This can be used, in conjunction with threshold, to grow a mask image outwards by a certain number of pixels.
The mask image may be the same image as this one, in which case it is destructively modified by this process.
| fillVal | ( | Xelval | gray | ) |
Sets the entire image (except the alpha channel) to the given grayscale level.
| fillVal | ( | Xelval | red, |
| Xelval | green, | ||
| Xelval | blue | ||
| ) |
Sets the entire image (except the alpha channel) to the given color.
| flip | ( | bool | flip_x, |
| bool | flip_y, | ||
| bool | transpose | ||
| ) |
Reverses, transposes, and/or rotates the image in-place according to the specified parameters.
If flip_x is true, the x axis is reversed; if flip_y is true, the y axis is reversed. Then, if transpose is true, the x and y axes are exchanged. These parameters can be used to select any combination of 90-degree or 180-degree rotations and flips.
| float fromAlphaVal | ( | Xelval | input_value | ) |
A handy function to scale alpha values from [0..get_maxval()] to [0..1].
| LRGBColorf fromVal | ( | const Xel | input_value | ) |

Do not use this for alpha values, see from_alpha_val.
| gammaCorrect | ( | float | from_gamma, |
| float | to_gamma | ||
| ) |
Assuming the image was constructed with a gamma curve of from_gamma in the RGB channels, converts it to an image with a gamma curve of to_gamma in the RGB channels.
Does not affect the alpha channel.
| gammaCorrectAlpha | ( | float | from_gamma, |
| float | to_gamma | ||
| ) |
Assuming the image was constructed with a gamma curve of from_gamma in the alpha channel, converts it to an image with a gamma curve of to_gamma in the alpha channel.

Typically pixel_values will be a 256x1 image.
Fills the PNMImage with a new image the same width and height as index_image, with the same number of channels as pixel_values.
Each pixel of the new image is computed with the formula:
new_image(x, y) = pixel_values(index_image(x, y)[channel], 0)
At present, no interpolation is performed; the nearest value in pixel_values is discovered. This may change in the future.
| bool isValid | ( | ) |

| int | yto, | ||
| int | xfrom, | ||
| int | yfrom, | ||
| int | x_size, | ||
| int | y_size, | ||
| float | pixel_scale | ||
| ) |
Behaves like copy_sub_image(), but the resulting color will be the lighter of the source and destination colors at each pixel (and at each R, G, B, A component value).

Behaves like copy_sub_image(), except the copy pixels are multiplied to the pixels of the destination, after scaling by the specified pixel_scale.
Unlike blend_sub_image(), the alpha channel is not treated specially.

| PNMImage operator*= | ( | float | multiplier | ) |
| PNMImage::Row operator[] | ( | int | y | ) |
| PNMImage::CRow operator[] | ( | int | y | ) |

| perlinNoiseFill | ( | float | sx, |
| float | sy, | ||
| int | table_size, | ||
| unsigned long int | seed | ||
| ) |
Fills the image with a grayscale perlin noise pattern based on the indicated parameters.
Uses set_xel to set the grayscale values. The sx and sy parameters are in multiples of the size of this image. See also the PerlinNoise2 class in mathutil.
| perlinNoiseFill | ( | StackedPerlinNoise2 | perlin | ) |
Variant of perlin_noise_fill that uses an existing StackedPerlinNoise2 object.
| premultiplyAlpha | ( | ) |
Converts an image in-place to its "premultiplied" form, where, for every pixel in the image, the red, green, and blue components are multiplied by that pixel's alpha value.
This does not modify any alpha values.
| quantize | ( | int | max_colors | ) |
Reduces the number of unique colors in the image to (at most) the given count.
Fewer colors than requested may be left in the image after this operation, but never more.
At present, this is only supported on images without an alpha channel.
| quickFilterFrom | ( | const PNMImage | copy, |
| int | xborder, | ||
| int | yborder | ||
| ) |
Resizes from the given image, with a fixed radius of 0.5.
This is a very specialized and simple algorithm that doesn't handle dropping below the Nyquist rate very well, but is quite a bit faster than the more general box_filter(), above. If borders are specified, they will further restrict the size of the resulting image. There's no point in using quick_box_filter() on a single image.
| bool read | ( | const Filename | filename, |
| PNMFileType | type, | ||
| bool | report_unknown_type | ||
| ) |
Reads the indicated image filename.
If type is non-NULL, it is a suggestion for the type of file it is. Returns true if successful, false on error.
| bool read | ( | Istream | data, |
| str | filename, | ||
| PNMFileType | type, | ||
| bool | report_unknown_type | ||
| ) |
Reads the image data from the indicated stream.
The filename is advisory only, and may be used to suggest a type if it has a known extension.
If type is non-NULL, it is a suggestion for the type of file it is (and a non-NULL type will override any magic number test or filename extension lookup).
Returns true if successful, false on error.
| bool read | ( | PNMReader | reader | ) |
This flavor of read() uses an already-existing PNMReader to read the image file.
You can get a reader via the PNMImageHeader::make_reader() methods. This is a good way to examine the header of a file (for instance, to determine its size) before actually reading the entire image.
The PNMReader is always deleted upon completion, whether successful or not.
| remixChannels | ( | const LMatrix4 | conv | ) |
Transforms every pixel using the operation (Ro,Go,Bo) = conv.xform_point(Ri,Gi,Bi); Input must be a color image.
| removeAlpha | ( | ) |
Removes the image's alpha channel, if it exists.
Renders a solid-color circle, with a fuzzy edge, into the center of the PNMImage.
If the PNMImage is non-square, this actually renders an ellipse.
The min_radius and max_radius are in the scale 0..1, where 1.0 means the full width of the image. If min_radius == max_radius, the edge is sharp (but still antialiased); otherwise, the pixels between min_radius and max_radius are smoothly blended between fg and bg colors.
| rescale | ( | float | min_val, |
| float | max_val | ||
| ) |
Rescales the RGB channel values so that any values in the original image between min_val and max_val are expanded to the range 0 .
. 1. Values below min_val are set to 0, and values above max_val are set to 1. Does not affect the alpha channel, if any.
| reverseRows | ( | ) |
Performs an in-place reversal of the row (y) data.
| setAlpha | ( | int | x, |
| int | y, | ||
| float | a | ||
| ) |
Sets the alpha component color only at the indicated pixel.
It is an error to call this unless has_alpha() is true. The value given should be in the range 0..1.
| setAlphaVal | ( | int | x, |
| int | y, | ||
| Xelval | a | ||
| ) |
Sets the alpha component color only at the indicated pixel.
It is an error to call this unless has_alpha() is true. The value given should be in the range 0..maxval.
This value is always linearly encoded, even if the image is set to the sRGB color space.
| setBlue | ( | int | x, |
| int | y, | ||
| float | b | ||
| ) |
Sets the blue component color only at the indicated pixel.
The value given should be a linearized float in the range 0..1.
| setBlueVal | ( | int | x, |
| int | y, | ||
| Xelval | b | ||
| ) |
Sets the blue component color only at the indicated pixel.
The value given should be in the range 0..maxval, encoded in the configured color space. See set_blue if you instead have a linearized and normalized floating-point value.
| setChannel | ( | int | x, |
| int | y, | ||
| int | channel, | ||
| float | value | ||
| ) |
Sets the nth component color at the indicated pixel.
The channel index should be in the range 0..(get_num_channels()-1). The channels are ordered B, G, R, A. This is slightly less optimal than setting the component values directly by named methods. The value given should be a float in the range 0..1.
| setChannelVal | ( | int | x, |
| int | y, | ||
| int | channel, | ||
| Xelval | value | ||
| ) |
Sets the nth component color at the indicated pixel.
The channel index should be in the range 0..(get_num_channels()-1). The channels are ordered B, G, R, A. This is slightly less optimal than setting the component values directly by named methods. The value given should be in the range 0..maxval.
| setColorSpace | ( | ColorSpace | color_space | ) |
Converts the colors in the image to the indicated color space.
This may be a lossy operation, in particular when going from sRGB to linear. The alpha channel remains untouched.
Note that, because functions like get_xel() and set_xel() work on linearized floating-point values, this conversion won't affect those values (aside from some minor discrepancies due to storage precision). It does affect the values used by get_xel_val() and set_xel_val(), though, since those operate on encoded colors.
Some color spaces, particularly scRGB, may enforce the use of a particular maxval setting.
| setColorType | ( | PNMImageHeader::ColorType | color_type | ) |
Translates the image to or from grayscale, color, or four-color mode.
Grayscale images are converted to full-color images with R, G, B set to the original gray level; color images are converted to grayscale according to the value of Bright(). The alpha channel, if added, is initialized to zero.
| setGray | ( | int | x, |
| int | y, | ||
| float | gray | ||
| ) |
Sets the gray component color at the indicated pixel.
This is only meaningful for grayscale images; for other image types, this simply sets the blue component color. However, also see set_xel(), which can set all the component colors to the same grayscale level, and hence works correctly both for grayscale and color images. The value given should be a linearized float in the range 0..1.
| setGrayVal | ( | int | x, |
| int | y, | ||
| Xelval | gray | ||
| ) |
Sets the gray component color at the indicated pixel.
This is only meaningful for grayscale images; for other image types, this simply sets the blue component color. However, also see set_xel_val(), which can set all the component colors to the same grayscale level, and hence works correctly both for grayscale and color images. The value given should be in the range 0..maxval, encoded in the configured color space. See set_gray if you instead have a linearized normalized floating-point value.
| setGreen | ( | int | x, |
| int | y, | ||
| float | g | ||
| ) |
Sets the green component color only at the indicated pixel.
The value given should be a linearized float in the range 0..1.
| setGreenVal | ( | int | x, |
| int | y, | ||
| Xelval | g | ||
| ) |
Sets the green component color only at the indicated pixel.
The value given should be in the range 0..maxval, encoded in the configured color space. See set_green if you instead have a linearized and normalized floating-point value.
| setMaxval | ( | Xelval | maxval | ) |
Rescales the image to the indicated maxval.
| setNumChannels | ( | int | num_channels | ) |
Changes the number of channels associated with the image.
The new number of channels must be an integer in the range 1 through 4, inclusive. This will allocate and/or deallocate memory as necessary to accommodate; see set_color_type().
| setPixel | ( | int | x, |
| int | y, | ||
| const PNMImageHeader::PixelSpec | pixel | ||
| ) |
Sets the (r, g, b, a) pixel value at the indicated pixel, using a PixelSpec object.
| setReadSize | ( | int | x_size, |
| int | y_size | ||
| ) |
Specifies the size to we'd like to scale the image upon reading it.
This will affect the next call to read(). This is usually used to reduce the image size, e.g. for a thumbnail.
If the file type reader supports it (e.g. JPEG), then this will scale the image during the read operation, consequently reducing memory and CPU utilization. If the file type reader does not support it, this will load the image normally, and them perform a linear scale after it has been loaded.
| setRed | ( | int | x, |
| int | y, | ||
| float | r | ||
| ) |
Sets the red component color only at the indicated pixel.
The value given should be a linearized float in the range 0..1.
| setRedVal | ( | int | x, |
| int | y, | ||
| Xelval | r | ||
| ) |
Sets the red component color only at the indicated pixel.
The value given should be in the range 0..maxval, encoded in the configured color space. See set_red if you instead have a linearized and normalized floating-point value.

| int | y, | ||
| const LRGBColorf | value | ||
| ) |
Changes the RGB color at the indicated pixel.
Each component is a linearized float in the range 0..1.
| setXel | ( | int | x, |
| int | y, | ||
| float | gray | ||
| ) |
Changes all three color components at the indicated pixel to the same value.
The value is a linearized float in the range 0..1.

| int | y, | ||
| float | r, | ||
| float | g, | ||
| float | b | ||
| ) |
Changes the RGB color at the indicated pixel.
Each component is a linearized float in the range 0..1.

| float | a | ||
| ) |

| ) |
Changes the RGB color at the indicated pixel.
Each component is in the range 0..maxval, encoded in the configured color space. See set_xel if you instead have a linearized and normalized floating-point value.

| Xelval | gray | ||
| ) |
Changes all three color components at the indicated pixel to the same value.
The value is in the range component is in the range 0..maxval, encoded in the configured color space. See set_xel if you instead have a linearized and normalized floating-point value.

| Xelval | g, | ||
| Xelval | b | ||
| ) |

Each component is in the range 0..maxval, encoded in the configured color space. See set_xel if you instead have a linearized and normalized floating-point value.
| takeFrom | ( | PNMImage | orig | ) |
Move the contents of the other image into this one, and empty the other image.
| threshold | ( | const PNMImage | select_image, |
| int | channel, | ||
| float | threshold, | ||
| const PNMImage | lt, | ||
| const PNMImage | ge | ||
| ) |
Selectively copies each pixel from either one source or another source, depending on the pixel value of the indicated channel of select_image.
For each pixel (x, y):
s = select_image.get_channel(x, y, channel). Set this image's (x, y) to:
lt.get_xel(x, y) if s < threshold, or
ge.get_xel(x, y) if s >= threshold
Any of select_image, lt, or ge may be the same PNMImge object as this image, or the same as each other; or they may all be different. All images must be the same size. As a special case, lt and ge may both be 1x1 images instead of the source image size.
| Xelval toAlphaVal | ( | float | input_value | ) |

Do not use this for alpha values, see to_alpha_val.
| unfilteredStretchFrom | ( | const PNMImage | copy | ) |
Resizes from the indicated image into this one by performing a nearest- point sample.
| unpremultiplyAlpha | ( | ) |
Converts an image in-place to its "straight alpha" form (presumably from a "premultiplied" form), where, for every pixel in the image, the red, green, and blue components are divided by that pixel's alpha value.
This does not modify any alpha values.
| bool write | ( | const Filename | filename, |
| PNMFileType | type | ||
| ) |
Writes the image to the indicated filename.
If type is non-NULL, it is a suggestion for the type of image file to write.
| bool write | ( | Ostream | data, |
| str | filename, | ||
| PNMFileType | type | ||
| ) |

This flavor of write() uses an already-existing PNMWriter to write the image file.
You can get a writer via the PNMImageHeader::make_writer() methods.
The PNMWriter is always deleted upon completion, whether successful or not.


If the circles are expected to move or change as the program executes then each one should be an object. For example, in a game where the circles represent playing pieces we need to keep track of the current location of each circle and too apply methods that move it.
Circle
Class
class Circle { // variables // constructors // methods } |
So our Circle
will be a drawing tool.
The circles drawn in the picture will merely be the traces left
behind each time the tool is used.
A start on the class is at the left.
Let us think about the variables that a Circle
needs.
