    libPGF

    libPGF

    libPGF is an implementation of the Progressive Graphics File (PGF)

    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.

    Clean implementation (in ANSI-C) of the Wavelets Transform. It works fairy good as a sparser, which can be combined with a compression algorithm (by using programs like bzip and gzip) to achieve high compression ratios (as good as mp3's).
