Open Source Perl Graphics Software

Perl library and command-line application for reading, writing and editing meta information (EXIF, IPTC, XMP, and more) in a wide variety of file formats (JPEG, TIFF, PNG, PDF, RAW, and more).

GraphicsMagick provides a set of commandline tools and programming APIs for manipulating, editing, and converting raster and vector images. It is derived from ImageMagick, with the objective of providing better stability and performance than ImageMagick while retaining the original MIT/X11 license.

A comprehensive software suite for reading barcodes. Supports EAN/UPC, Code 128, Code 39, Interleaved 2 of 5 and QR Code. Includes libraries and applications for decoding captured barcode images and using a video device (eg, webcam) as a barcode scanner.

ExifTool is a battle-tested Perl application for reading, writing, and batch-editing metadata in thousands of file types—images, videos, audio, documents, and more. It understands major standards like EXIF, IPTC, and XMP as well as an enormous range of camera maker notes and container formats (for example, QuickTime/MP4, PDF, TIFF). Typical workflows include extracting metadata to JSON/CSV/XML, renaming files from timestamps or tags, shifting capture times, copying tags between files, and cleaning or normalizing fields for archives. The tool is meticulous about character encodings, time zones, and tag groups, helping avoid silent corruption when moving metadata between ecosystems. It is scriptable and composable, with options to operate recursively, write sidecars, preserve originals, or do dry runs for safety. Professionals rely on ExifTool for digital asset management, forensic workflows, and any pipeline where metadata quality and traceability matter.

A GUI to ease the process of producing a multipage PDF from a scan. gscan2pdf should work on almost any Linux/BSD machine.

A whole bunch of utilities for primitive manipulation of graphic images. Wide array of converters from one graphics format to another. E.g. from g3 fax format to jpeg. Many basic graphics editing tools such as magnifying and cropping.

ImageMagick® is a free and open-source software suite for displaying, converting, and editing raster image and vector image files. It can read and write over 200 image file formats, and can support a wide range of image manipulation operations, such as resizing, cropping, and color correction. ImageMagick is written in C and is available for a wide range of operating systems, including Linux, macOS, and Windows. It can be used as a standalone application, or as a library that can be integrated into other software programs. Overall, ImageMagick is a powerful and versatile software suite for displaying, converting, and editing image files. Its support for scripting and automation, along with its other features, make it a valuable tool for a wide range of image-related tasks.

Open-source and cross-platform picture manager and organizer with complete meta information support: add, edit, search and remove XMP, IPTC, EXIF and JPEG Comment. It also offers batch conversion/renaming of images and lossless rotation and cropping.

WACS is a tool for building Adult Web Sites; equally suitable for managing a private collection or building a commercial site. It has many powerful features including dynamic filtering, model catalogs, automatic download and powerful search engine.

The littleutils include duplicate file finders (repeats, repeats.pl, repeats.py), image optimizers (opt-jpg, opt-png, opt-gif, recomp-jpg), file rename tools (lowercase, uppercase, pren), archive recompressors (to-gzip, to-bzip2, to-bzip3, to-7zip, to-lzma, to-lzip, to-xz), a tempfile utility (tempname), file property tools (filedate, filemode, filenode, fileown, filesize, and lrealpath), and others. See the README file for more details.

adesklets is an interactive Imlib2 console for the X Window System. It provides to scripted languages a clean and simple way to write great looking, mildly interactive desktop integrated graphic applets (aka "desklets").

ZoneMinder is video and cctv surveillance and security application. It supports multiple video or IP cameras and a sophisticated motion detection system based around zones. Both live streams and historic events can be viewed via the web interface.

EPSILON is a powerful Open Source wavelet image compressor. The project is aimed on parallel and robust image processing.

Viewer / Extractor for compressed HTML in the Mozilla Archive Format (*.maff file) Maff-viewer works fully offline and uses your prefered browser to display the extracted maff-file content. For details see https://sourceforge.net/projects/maff-viewer/files/Maff-Viewer_Doku.pdf/download

Cvsplot is a perl script which analyses the history of a CVS-managed project. The script executes on a set of files, analyses their history, and automatically generates graphs that plot lines of code and number of files against time.

Agar provides a base GUI framework and a standard set of widgets from which graphical applications can be built which run natively under X11, Windows, MacOS X, SDL and others. It takes advantage of texture and GPU acceleration wherever available. Agar can also attach to an existing framebuffer, SDL or OpenGL context and operate as a self-contained window-manager. It includes a standard library of general-purpose widgets, and is also designed to be extended externally. New widgets can be implemented as part of an application or library. Complex user interface elements can be realized often in few lines of code. Agar is also extensible at the low-level. The low-level API is documented such that modular drivers can be written which enable Agar applications to work seamlessly under many platforms graphics systems without any change at the application level.

GGI stands for "General Graphics Interface", and it is a project that aims to develop a reliable, stable and fast graphics system that works everywhere. We want to allow any program using GGI to run on any platform requiring at most a recompile.

Kalva is a lightweight videoapplication using MPlayer and MEncoder to do the real work (schedules via atd and crond). Kalva's main goal is to be quite simple to setup and easy to use. But apart from that it provides quite some useful features.

AfterGlow is a scripts which facilitates the process of generating link graphs from CSV input. AfterGlow is written in Perl and generates output that can be read by GraphViz, Gephi, etc. Source: https://github.com/zrlram/afterglow Tarball: http://pixlcloud.com/afterglow-2
