PGF Console contains an implementation of the Progressive Graphics File (PGF). which is a new image file format, that is based on a discrete, fast wavelet transform with progressive coding features. PGF can be used for lossless and lossy compression.

PGF is a new progressive file format for lossy and lossless image compression.

Usage:
- Encoding: pgf -e [-l levels] [-q quality] [-r] [-s] [-v] source destination.
Create from a source file a PGF image (destination file). The most popular image file formats with the following image types are supported:
- bitmap (1 bit)
- grayscale (8 and 16 bit)
- indexed color (8 bit)
- RGB (16 [565], 24, 32, and 48 bit)
- RGBA (32 bit)
Options:
-l levels Number of hierarchical levels [1..30]. Default is 0. 0 means the number of levels are automatically set.
-q quality Quality [0..31]. Default is 0. 0 means perfect quality (lossless compression), 31 means maximum compression.
-r Region of interest (ROI) encoding scheme is used. This encoding scheme has a slightly worse compression ratio.
-s Level wise encoding in separate writing calls.
-v Numbers only: All text output is reduced to numbers.

- Decoding: pgf -d [-rect left top width height] [-s] [-v] source destination. Create from a PGF image (source file) a new image (destination file).
Options:
-rect rect Read a rectangular region of a PGF image supporting Region of interests (ROI). The rectangle is defined by its top-left corner and a positive width and height.
-s Level wise decoding in separate reading calls.
-v Numbers only: All text output is reduced to numbers.

- Measuring: pgf -m temp-file [...] source destination. Measure quality between source and destination bitmap. Encode from an input image (source file) a PGF image (temp-file) and decode from the PGF image a new output input (destination file).
Options:
All encoding and decoding options are valid.
