APNG (Animated Portable Network Graphics) is an unofficial extension of the APNG (Portable Network Graphics) format. APNG patch provides APNG support to libpng.

imgp is a command line image resizer and rotator for JPEG and PNG images. It can resize (or thumbnail) and rotate thousands of images in a go while saving significantly on storage.

This package may optionally be built with python-pillow-simd in place of python-pillow for SIMD parallelism.

Libavif is a C implementation of AVIF. It can encode and decode all YUV formats and bit depths supported by AOM, including with alpha.

Imlib2 is a library that does image file loading and saving as well as rendering, manipulation, arbitrary polygon support, etc.

It does ALL of these operations FAST. Imlib2 also tries to be highly intelligent about doing them, so writing naive programs can be done easily, without sacrificing speed.

This is a complete rewrite over the Imlib 1.x series. The architecture is more modular, simple, and flexible.

GIFLIB is a library for reading and writing GIF images. It is API and ABI compatible with libungif which was in wide use while the LZW compression algorithm was patented. Tools are also included to convert, manipulate, compose, and analyze GIF images.

A pretty small png library. Currently all documentation resides in pnglite.h.

pngquant is a PNG compressor that significantly reduces file sizes by converting images to a more efficient 8-bit PNG format with alpha channel (often 60-80% smaller than 24/32-bit PNG files). Compressed images are fully standards-compliant and are supported by all web browsers and operating systems.

Features:

1. High-quality palette generation using a combination of vector quantization algorithms.

2. Unique adaptive dithering algorithm that adds less noise to images than the standard Floyd-Steinberg.

3. Easy to integrate with shell scripts, GUIs and server-side software.

4. Fast mode for real-time processing/large numbers of images.

libjpeg-turbo is a JPEG image codec that accelerates baseline JPEG compression and decompression using SIMD instructions: MMX on x86, SSE2 on x86-64, NEON on ARM, and AltiVec on PowerPC processors. Even on other systems, its highly-optimized Huffman coding routines allow it to outperform libjpeg by a significant amount. libjpeg-turbo implements both the traditional libjpeg API and the less powerful but more straightforward TurboJPEG API, and provides a full-featured Java interface. It supports color space extensions that allow it to compress from and decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.).

Picket is a screen color picker that includes a magnifier and supports custom formats for representing color values..

grim can create screenshots from a Wayland compositor.

Gradia is a GTK 4 application for enhancing and preparing screenshots for blogs, social media, and documentation. It supports background customization, annotation tools (pen, arrow, text, highlight, stamp), padding, cropping, OCR and various export formats.

Giblib is a simple library which wraps imlib2's context API, avoiding all the context_get/set calls, adds fontstyles to the truetype renderer and supplies a generic doubly-linked list and some string functions.

This Perl extension allows the reading, manipulation and writing of a large number of image file formats using the ImageMagick library. Use it to create, edit, compose, or convert bitmap images from within a Perl script.

GraphicsMagick provides a comprehensive collection of utilities, programming interfaces, and GUIs, to support file format conversion, image processing, and 2D vector rendering.

ImageMagick is a software suite to create, edit, compose, or convert bitmap images. It can read and write images in a variety of formats (over 100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG, and TIFF. Use ImageMagick to resize, flip, mirror, rotate, distort, shear and transform images, adjust image colors, apply various special effects, or draw text, lines, polygons, ellipses and Bézier curves.

Inferno is a virtualised operating system that can run natively across a wide range of processor architectures or hosted on a wide range of operating systems. The principal components of the system are:

• The Inferno kernel which can run both native and hosted on a range of platforms and which presents the same interface to programs in both cases.

• The Dis virtual machine.

• Styx - the tiny broad-spectrum file service protocol.

• Limbo - a new simple, modular, concurrent programming language.

• Tk and Prefab - graphical user interface (GUI) primitives without a lot of goo.

• The portable cross-development suites that allow any native Inferno platform to be cross-compiled on any hosted system.

This package provides hosted Inferno.

GNU InklingReader is a package to support the Wacom Inkling device, including data conversion to various free formats, basic editing features, and an Inkscape plugin.

Inkscape is a vector graphics editor. What sets Inkscape apart is its use of Scalable Vector Graphics (SVG), an XML-based W3C standard, as the native format.

NSIS (Nullsoft Scriptable Install System) is a system to create Windows installers. It is designed to be as small and flexible as possible and is therefore very suitable for internet distribution.

Like Jacques Cartier, Jacques CTF can explore the sea of bits of a CTF data stream file and discover unsuspected lands of problems within packets.

The lttng-tools project provides a session daemon lttng-sessiond that acts as a tracing registry, the lttng command line for tracing control, a lttng-ctl library for tracing control and a lttng-relayd for network streaming.

Perf-tools is a collection of scripts for performance analysis and instrumentation based on Linux perf_events (aka perf) and ftrace.
