The Javascript Clipper library performs clipping and offsetting for both lines and polygons. All four boolean clipping operations are supported - intersection, union, difference and exclusive-or. Polygons can be of any shape including self-intersecting polygons. Javascript Clipper is a port of Angus Johnson's Clipper library: https://sourceforge.net/projects/polyclipping LIVE DEMO: http://jsclipper.sourceforge.net/6.4.2.2/main_demo.html LIVE DEMO (FPoint): http://jsclipper.sourceforge.net/6.4.2.2_fpoint/main_demo.html Information and examples: http://jsclipper.sourceforge.net/6.4.2.2 Information and examples (FPoint): http://jsclipper.sourceforge.net/6.4.2.2_fpoint Donate Javascript Clipper Project: https://sourceforge.net/p/jsclipper/wiki/Donations/ Use cases: * Over 1500 schools in the UK uses Javascript Clipper in Digimap for Schools service.

The Progressive Graphics File (PGF) is an efficient image file format, that is based on a fast, discrete wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression. It's most suitable for natural images. PGF can be used as a very efficient and fast replacement of JPEG 2000.

IVCon-TL can read and write a variety of 3D graphics file formats, converting from one to the other. Supported formats include 3DS, ASE, BYU, DXF, GMOD, HRC, IV, OBJ, OFF, POV, SMF, STL/STLA/STLB, TEC, TRI/TRIA/TRIB, UCD, VLA, WRL/VRML, XGL and more.

CADI is an implementation of the JPIP standard (JPEG2000 Interactive Protocol - Part 9). CADI includes a JPIP server, a JPIP proxy, and a JPIP Client. CADI is designed and programmed with the aim to provide a flexible framework to test and develop ne

Use, study and develop advanced digital halftoning algorithms with Halftone Laboratory, a GIMP plug-in backed by a highly modular and extensible library. It uses .NET/Mono and GIMP#.

Bookinex is an application designed to index your collection of books, it supports scanning of Barcodes to recognize ISB Numbers and querying web services to collect data.

C-squares is an easily implemented method for storage, querying and display of spatial data locations, based on a hierarchical, grid-based representation of the Earth' surface. Source code for encoding, decoding, mapping, etc. is provided via this site. Additional support is available by contacting the system developer, Tony.Rees@marinespecies.org; see also the c-squares home page at http://www.cmar.csiro.au/csquares/ .

A Color Management System library implement by Java language.

An OpenGL GUI for the inspection and segmentation of 3D surface meshes

This is an image coder with fixed sampling, at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with res. up to 352x288).

MobileMath is a software written by using J2ME technolology. It turns mobile into calculator supporting many operations such as : evaluate expression, plotting, differentiate & integrate expression... It can run on any mobiles supporting Java.

NESD-Imaging is a 2D rendering framework for Java. It combines JAI and Java2D and extends them by providing lazy rendering (do not block UI). It provides geo-positionned images rendering (à la google-map). It scales well to large image set (>500GB).

A very well optimized coherent noise-generating library for C++ under BSD-style license

The goal of an Open Math Library is to provide the basic set of math-related classes and functions for 3d engine development. Currently the library has implementations for vectors (2 to 4 dimensional), matrices, planes and quaternions.
