Open Source Java 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!

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.

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.

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

Xi3D is an X3D renderer and browser for 3D Web content. It contains compliant parsers for VRML'97 types, a java scenegraph, XML bindings using SAX2, a content converter, full runtime and event model, DOM Level 2, vecmath

blitz-image is a library to support extremely fast image processing in java, harnessing GPU acceleration via OpenCL. Although more features will be added in time, the initial focus is on very fast high-quality image resizing, including bicubic resizing (both upscale and downscale). The performance of a typical bicubic upscale operation is typically in the order of 10 times faster than via the standard AWT mechanism using RenderingHints.VALUE_INTERPOLATION_BICUBIC. The library depends on Aparapi (https://code.google.com/p/aparapi/). Any GPU supporting OpenCL should be supported (including low-end GPUs without double-precision fp support), and there is automatic fallback to pure java implementations for all operations in the event that there is no OpenCL support available. A high-level API allows for very easy use from AWT/Swing, whilst the low-level array-based API allows integration with any imaging framework (e.g. from Android or SWT).

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
