DESCRIPTION    [Toc]    [Back]

     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.
