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

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.).

swappy is a command-line utility to take and edit screenshots of Wayland desktops. Works great with grim, slurp and sway. But can easily work with other screen copy tools that can output a final PNG image to stdout.

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

Libiptcdata is a C library for manipulating the International Press Telecommunications Council (IPTC) metadata stored within multimedia files such as images. This metadata can include captions and keywords, often used by popular photo management applications. The library provides routines for parsing, viewing, modifying, and saving this metadata.

Libtiff provides support for the Tag Image File Format (TIFF), a format used for storing image data. Included are a library, libtiff, for reading and writing TIFF and a small collection of tools for doing simple manipulations of TIFF images.

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.

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

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.

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.

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.

The user space tracing library, liblttng-ust, is the LTTng user space tracer. It receives commands from a session daemon, for example to enable and disable specific instrumentation points, and writes event records to ring buffers shared with a consumer daemon.

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.

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.

barectf is a generator of tracer which produces CTF data streams. The generated C source code has no other dependencies than a few C standard library headers.
