iflPNG(3)

NAME

iflPNG - a PNG formatted image file

HEADER FILE

#include <ifl/iflPNG.h>

DESCRIPTION

The Image Format Library provides support for reading and writing image files with the Portable Network Graphics format (PNG), revision 0.88. This file format is suitable for archiving multicolor and monochromatic image data.

As specified by the PNG Compression field, iflPNG can support several compression algorithms. Currently only the zlib deflate/inflate is defined. Note that it is not possible to specify that no compression should be performed but the degree of compression can be controlled to some extent.

Note that the PNG format does not support image tiling.

The default extension for image files in the PNG format is '.png'. When you create a file with that extension IFL will assume you want the PNG format, unless you override it with the iflFormat parameter.
