JBIG-KIT implements the JBIG1 data compression standard (ITU-T T.82 and ISO/IEC 11544:1993), designed for bi-level (one bit per pixel) images such as black-and-white scanned documents. It is widely used in fax products, printer firmware and drivers, document management systems, and imaging software.

This package provides a static C library of (de)compression functions and some simple command-line converters similar to those provided by netpbm.

Two JBIG1 variants are available. One (jbig.c) implements nearly all options of the standard but has to keep the full uncompressed image in memory. The other (jbig85.c) implements just the ITU-T T.85 profile, with memory management optimized for embedded and fax applications. It buffers only a few lines of the uncompressed image in memory and is able to stream images of initially unknown height.

Libjpeg implements JPEG image encoding, decoding, and transcoding. JPEG is a standardized compression method for full-color and gray-scale images. It also includes programs that provide conversion between the JPEG format and image files in PBMPLUS PPM/PGM, GIF, BMP, and Targa file formats, as well as lossless JPEG manipulations such as rotation, scaling or cropping:

1. cjpeg

2. djpeg

3. jpegtran

4. rdjpgcom

5. wrjpgcom

JPEG XR is an approved ISO/IEC International standard (its official designation is ISO/IEC 29199-2). This library is an implementation of that standard.

Gpick is an advanced color picker and palette editing tool.

Libpng is the official PNG (Portable Network Graphics) reference library. It supports almost all PNG features and is extensible.

Slurp can select a region in a Wayland compositor and print it to the standard output. It works well together with grim.

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.).

Nifti_clib is a set of I/O libraries for reading and writing files in the nifti-1, nifti-2, and (to some degree) cifti file formats. These are binary file formats for storing medical image data, e.g. MRI and fMRI brain images.

Leptonica is a C library and set of command-line tools for efficient image processing and image analysis operations. It supports rasterop, affine transformations, binary and grayscale morphology, rank order, and convolution, seedfill and connected components, image transformations combining changes in scale and pixel depth, and pixelwise masking, blending, enhancement, and arithmetic ops.

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.

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.

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.

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

SystemTap provides infrastructure to simplify the gathering of information about the running Linux system. This assists diagnosis of a performance or functional problem. SystemTap eliminates the need for the developer to go through the tedious and disruptive instrument, recompile, install, and reboot sequence that may be otherwise required to collect data.

SystemTap provides a simple command line interface and scripting language for writing instrumentation for a live running kernel plus user-space applications. We are publishing samples, as well as enlarging the internal "tapset" script library to aid reuse and abstraction. SystemTap is a tool for complex tasks that may require live analysis, programmable on-line response, and whole-system symbolic access, and can also handle simple tracing jobs.

LTTng kernel modules are Linux kernel modules which make LTTng kernel tracing possible. They include essential control modules and many probes which instrument numerous interesting parts of Linux.

While the CTF reading libraries focus on decoding and providing completed and ordered event record objects, the yactfr API offers a lower level of CTF processing. Allowing iteration over individual element sequences to obtain elements: beginning/end of packet, beginning/end of event record, beggining/end of structure, individual data stream scalar values like fixed-length integers, fixed-length floating point numbers, and null-terminated strings, specific clock value update, known data stream ID, and the rest.

Babeltrace 2 is a framework for viewing, converting, transforming, and analyzing traces. It is also the reference parser implementation of the Common Trace Format (CTF), produced by tools such as LTTng and barectf. This package provides a library with a C API, Python 3 bindings, and the command-line tool babeltrace2.
