PNG to PGM

Useful information about PNG

Extension: PNG
Name: Portable Network Graphics
Mime Type: image/png
Converter: PNG Converter
Description: Portable Network Graphics (PNG) is a raster-graphics file format that supports lossless data compression. PNG was developed as an improved, non-patented replacement for Graphics Interchange Format (GIF) — unofficially, the initials PNG stood for the recursive acronym 'PNG's not GIF'.
PNG supports palette-based images (with palettes of 24-bit RGB or 32-bit RGBA colors), grayscale images (with or without an alpha channel for transparency), and full-color non-palette-based RGB or RGBA images. The PNG working group designed the format for transferring images on the Internet, not for professional-quality print graphics; therefore non-RGB color spaces such as CMYK are not supported. A PNG file contains a single image in an extensible structure of chunks, encoding the basic pixels and other information such as textual comments and integrity checks documented in RFC 2083.
PNG files use the file extension PNG or png and are assigned MIME media type image/png. PNG was published as informational RFC 2083 in March 1997 and as an ISO/IEC 15948 standard in 2004. - Source

Useful information about PGM

Extension: PGM
Name: Portable Gray Map
Mime Type: image/x-portable-graymap
Converter: PGM Converter
Description: The PGM format is a lowest common denominator grayscale file format. It is designed to be extremely easy to learn and write programs for. (It's so simple that most people will simply reverse engineer it because it's easier than reading this specification). A PGM image represents a grayscale graphic image. There are many pseudo-PGM formats in use where everything is as specified herein except for the meaning of individual pixel values. For most purposes, a PGM image can just be thought of an array of arbitrary integers, and all the programs in the world that think they're processing a grayscale image can easily be tricked into processing something else. - Source
