iflPNG(3) Image Format Library C++ Reference Manual 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.
