The Portable Network Graphic filter imports and exports Portable Network Graphic .PNG files.
Portable Network Graphics .PNG is an image format that employs lossless data compression. PNG was created to improve upon and replace GIF (Graphics Interchange Format) as an image-file format not requiring a patent license.
The .PNG format is one of the few image formats with complete support for alpha channels (transparency). PNG supports palette-based, greyscale, or RGB images. PNG does not support CMYK color spaces.
