Open Source Linux Image Converters

FreeImage is a library project for developers who would like to support popular graphics image formats (PNG, JPEG, TIFF, BMP and others). Some highlights are: extremely simple in use, not limited to the local PC (unique FreeImageIO) and Plugin driven!

Converseen is a free cross-platform batch image processor for Windows, Linux, macOS, FreeBSD, and other operating systems. It allows you to convert, resize, rotate, and flip an infinite number of images with a single mouse click. Moreover, Converseen can convert an entire PDF document into a set of images with your preferred characteristics. You can choose from over 100+ formats, set the size, resolution, and the filename. Thanks to ImageMagick, the powerful image manipulation library, Converseen can handle more than 100 image formats, including DPX, EXR, GIF, JPEG, JPEG-2000, PNG, SVG, TIFF, WebP, HEIC/HEIF, and many others. Converseen is designed to be user-friendly, fast, practical, and best of all, it’s available for free!

Luminance HDR is a complete suite for HDR imaging workflow. It provides a wide range of functionalities, during both the fusion stage and the tonemapping stage. Its graphical user interface, based on Qt5, runs on a variety of platforms, such as Microsoft Windows, Mac OS X 10.9 and later and several Unix flavors (Linux, FreeBSD and others). Input images can be supplied in multiple formats, from JPEG to RAW files. In the same way, output can be saved in many different formats as well, from JPEG to TIFF (both 8 bit and 16 bit per channel), enabling all the power of your post processing tools.

pfstools - a set of programs for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames. pfscalibration - photometric calibration of cameras and HDR images from multiple exposures. pfstmo - tone mapping operators.

Kabeja is a java library for parsing DXF and converting to SVG (dxf2svg). The library supports the SAX-api and can integrated into other applications (Cocoon,Batik). Tools for converting svg to jpeg, tiff, png and pdf are included .

Drawj2d creates technical line drawings using a descriptive language. It writes pdf, svg, eps, emf and dxf vector graphics or png images. It runs on all platforms that run Java. It is inspired by Asymptote but with a tcl-like syntax and 2D only.

A C#/.net-library for encoding and decoding DataMatrix codes (based on a .net-port of libdmtx). DataMatrix.net also contains a small application for generating PDF documents containing different types of 1D- and 2D-codes.

Teem is a set of C libraries for manipulation, measurement, and visualization of structured scientific data. Includes N-dimensional image I/O and processing, volume rendering, diffusion tensor processing, and more. Latest code via git clone http://git.code.sf.net/p/teem/teem.git .

EasyBMP is an easy cross-platform C++ library for reading and writing Windows bitmap BMP files. No installation, no need for external libraries, small size, well-documented, and simple enough for the novice programmer to start in just minutes!

Huge collection of cliparts in Encapsulated PostScript format derived from Open Clip Art Library. Includes more than 6,500 clip arts freely available without restrictions for free use and distribution. Released as Public Domain.

html2fo is a converter from html to xsl:fo. The html code could be written with StarOffice or other WYSIWYM editors and must not be 100% valid html code. html2fo is designed to produce a valid xsl:fo for using FOP from Apache.

Narya is a forum/incubator software, based on a Python/Zope/MySQL platform. Emphasis on graphics support and collaboration for space and technology development. Compare PHP/MySQL forums.

PyPotrace is a Python programming language binding for Peter Selinger's Potrace raster to vector conversion algorithm. No separate Potrace library or application required!

jSVR is an implementation of the Single view 3D reconstruction technique. It allows the recreation of 3D scenes from a single image. It provides a UI that navigates the user through a number of steps from a source image to a complete 3dmodel of the scene

DarkMaps is a program that reads images and builds a 3D map from them.

An extensible TIFF codec for Java 1.2 Advanced Imaging, allowing for extended compression types, writing tiled images etc. Used by GeoTIFF-JAI project.

fax2pdf provides a means to convert sets of G3 fax pages (encoded in a TIFF variant) into PDF. This can be used to convert fax pages received with eg. HylaFAX into a file format readily accessible/viewable with programs on most platforms.

FreeMovie is an SWF generator library written in PHP and ported to Ruby. FreeMovie can be used to develop Web and desktop aplications.

This object-oriented python module converts 3D VRML models into Collada and integrates it in Google Earth (GE) through the Keyhole Markup Language (KML). It enables the visualisation of large scale aerial/satellite images in the Geo Browser.

Jaiom (Java All In One MediaProcessing Server) intends to provide a simple to use webservices based, media processing facade which processes videos, photos, pdf and MS Office media types using many different kind media processing engines.

Modama is a new software project for processing and analysing 2d detector data (images) provided by any available detectors, mainly SAX and WAX.

GimpPy uses img maps & an img as the input, output is a report.py file used to generate PDFs, the out files may run solo or chained together to make more complex multi page reports. Input required is a dict with vals for flds you have mapped on your img.

PhoXo Core Library (PCL) is a set of powerful image manipulation library for C++, it's OS independent and highlights are : Undo/Redo,multiple-layer,region selection,tens of image effect...

"Plot Extractor" allows manual extraction of point coordinates from an image. X and Y axes are manually defined by two points each. Axes need not be orthogonal and can be rotated compared to the image edges.
