gd
- Ebuilds: 1, Stable: 2.3.3-r4, Testing: 2.3.3-r4 Description:
gd is a graphics library. It allows your code to quickly draw images complete
with lines, arcs, text, multiple colors, cut and paste from other images, and
flood fills, and write out the result as a PNG or JPEG file. This is particularly
useful in World Wide Web applications, where PNG and JPEG are two of the formats
accepted for inline images by most browsers.
gd is not a paint program. If you are looking for a paint program, you are
looking in the wrong place. If you are not a programmer, you are looking in the
wrong place, unless you are installing a required library in order to run an
application.
gd does not provide for every possible desirable graphics operation. It is not
necessary or desirable for gd to become a kitchen-sink graphics package, but
version 2.0 does include most frequently requested features, including both
truecolor and palette images, resampling (smooth resizing of truecolor images)
and so forth.

imlib2
- Ebuilds: 4, Stable: 1.12.5, Testing: 1.12.6 Description:
Imlib 2 is the successor to Imlib. It is not just a newer version - it
is a completely new library. Imlib2 can be installed alongside Imlib
1.x without any problems since they are effectively different libraries
- but they Have very similar functionality.
Imlib2 can do the following:
* Load image files from disk in one of many formats,
* Save images to disk in one of many formats,
* Render image data onto other images,
* Render images to an X-Windows drawable,
* Produce pixmaps and pixmap masks of Images,
* Apply filters to images,
* Rotate images,
* Accept RGBA Data for images,
* Scale images,
* Alpha blend Images on other images or drawables,
* Apply color correction and modification tables and factors to
images,
* Render images onto images with color correction and modification
tables,
* Render truetype anti-aliased text,
* Render truetype anti-aliased text at any angle,
* Render anti-aliased lines,
* Render rectangles,
* Render linear multi-colored gradients,
* Cache data intelligently for maximum performance,
* Allocate colors automatically,
* Allow full control over caching and color allocation,
* Provide highly optimized MMX assembly for core routines,
* Provide plug-in filter interface,
* Provide on-the-fly runtime plug-in image loading and saving
interface,
* Fastest image compositing, rendering and manipulation library for X.
If what you want isn't in the list above somewhere then likely Imlib 2
does not do it. If it does it it likely does it faster than any other
library you can find (this includes gdk-pixbuf, gdkrgb, etc.) primarily
because of highly optimized code and a smart subsystem that does the
dirty work for you and picks up the pieces for you so you can be lazy
and let all the optimizations for you.
Imlib 2 can run without a display, so it can be easily used for
background image processing for web sites or servers - it only requires
the X libraries to be installed - that is all - it does not require an
XServer to run unless you wish to display images.

and Hebrew as easily as left-to-right scripts. Indic and Indic-derived
Complex Text Layout (CTL) scripts, such as Devanagari, Thai, Lao, and
Tibetan are supported to the extent provided by Pango and by the
OpenType fonts installed on your system. All of this is provided
without need for any special configuration or layout calculation on
the programmer's part.
libLASi was designed for projects which require the ability to
produce Postscript independent of any one application framework.

reasons best known to themselves, some developers release
binaries linked against libcurl-gnutls.so instead of
libcurl.so, the latter being the OpenSSL variant. Although it
is less than ideal, real world usage has shown that symlinking
from one to the other doesn't cause any issues so this package
provides such a symlink to satisfy prebuilt binaries. Usage of
libcurl-nss.so seems less common but a symlink for that has
also been included for completeness.

Libinsane is the library to access scanners on both Linux and Windows. It's cross-platform, cross-programming languages, cross-scanners :-). It takes care of all the quirks of all the platforms and scanners
It has however some limitations:
* It is only designed to work with scanners, not webcams, not USB keys, etc (think paper-eaters only)
* TWAIN API may display some dialogs. Libinsane cannot prevent them.
* Full bed page scan only: Presence of the option to set the scan area cannot be guaranteed. You may have to crop the image later in your own application (see Paperwork for example).
* 24 bits color scans only (may be fixed later)
It is the successor of Pyinsane2 but shares no code with it.

libkate
- Ebuilds: 1, Stable: 0.4.1-r4, Testing: 0.4.1-r4 Description: Kate is a codec for karaoke and text encapsulation for Ogg. Most of the
time, this would be multiplexed with audio/video to carry subtitles,
song lyrics (with or without karaoke data), etc, but doesn't have to be.
A possible use of a lone Kate stream would be an e-book. Moreover, the
motion feature gives Kate a powerful means to describe arbitrary curves,
so hand drawing of shapes can be achieved. This was originally meant for
karaoke use, but can be used for any purpose. Motions can be attached to
various semantics, like position, color, etc, so scrolling or fading
text can be defined.

- Ebuilds: 1, Stable: 1.32.0, Testing: 1.32.0 Description:
libv4l is a collection of libraries which adds a thin abstraction layer on
top of video4linux2 devices. The purpose of this (thin) layer is to make it
easy for application writers to support a wide variety of devices without
having to write separate code for different devices in the same class.
libv4l consists of 3 different libraries: libv4lconvert, libv4l1 and libv4l2.
libv4lconvert offers functions to convert from any (known) pixelformat
to V4l2_PIX_FMT_BGR24 or V4l2_PIX_FMT_YUV420.
libv4l1 offers the (deprecated) v4l1 API on top of v4l2 devices, independent
of the drivers for those devices supporting v4l1 compatibility (which many
v4l2 drivers do not).
libv4l2 offers the v4l2 API on top of v4l2 devices, while adding for the
application transparent libv4lconvert conversion where necessary.

libxmi
- Ebuilds: 2, Stable: 1.3-r2, Testing: 1.3-r2 Description:
GNU libxmi is a C/C++ function library for rasterizing 2-D vector graphics. It
can draw 2-D graphical primitives, including wide polygonal lines and circular
and elliptical arcs, into a user-supplied matrix of pixels. Sophisticated line
styles, such as multicolored dashing patterns, can be specified. There is also
support for filling and texturing polygons.
It can be used as a drop-in rendering module in any application that needs to
scan-convert 2-D vector graphics. It is highly customizable. For example, the
`pixel' datatype can be redefined at compile time. The algorithm used for
compositing pixels can be redefined too. By default, libxmi uses the
Painter's Algorithm (a new pixel value replaces an old one). But it would be
trivial to install it so that it uses alpha compositing instead. The package,
and its header file xmi.h, include full documentation.

rlottie
- Ebuilds: 1, Stable: 0.2_p20210405, Testing: 0.2_p20210405 Description:
rlottie is a platform independent standalone c++ library for rendering
vector based animations and art in realtime.
Lottie loads and renders animations and vectors exported in the bodymovin
JSON format. Bodymovin JSON can be created and exported from After Effects
with bodymovin, Sketch with Lottie Sketch Export, and from Haiku.
For the first time, designers can create and ship beautiful animations
without an engineer painstakingly recreating it by hand. Since the
animation is backed by JSON they are extremely small in size but can be
large in complexity!

sdl-gfx
- Ebuilds: 2, Stable: 2.0.26-r2, Testing: 2.0.26-r2 Description:
SDL graphics drawing primitives and other support functions
The SDL_gfx library evolved out of the SDL_gfxPrimitives code which provided basic drawing
routines such as lines, circles or polygons and SDL_rotozoom which implemented a
interpolating rotozoomer for SDL surfaces.
The current components of the SDL_gfx library are:
* Graphic Primitives (SDL_gfxPrimitves.h)
* Rotozoomer (SDL_rotozoom.h)
* Framerate control (SDL_framerate.h)
* MMX image filters (SDL_imageFilter.h)
The library is backwards compatible to the above mentioned code. Its is written in plain C
and can be used in C++ code.
