JNG to JPM

Useful information about JNG

Extension: JNG
Name: JPEG Network Graphics
Mime Type: image/jng
Converter: JNG Converter
Description: JPEG Network Graphics (JNG) is a JPEG-based graphics file format which is closely related to PNG: it uses the PNG file structure (with a different signature) as a container format to wrap JPEG-encoded image data. JNG was created as an adjunct to the MNG animation format, but may be used as a stand-alone format. JNG files embed an 8-bit or 12-bit JPEG datastream in order to store color data, and may embed another datastream (1, 2, 4, 8, 16-bit PNG, or 8-bit JPEG grayscale image) for transparency information. However, a JNG may contain two separate JPEG datastreams for color information (one 8-bit and one 12-bit) to permit decoders that are unable to (or do not wish to) handle 12-bit datastreams to display the 8-bit datastream instead, if one is present. - Source

Useful information about JPM

Extension: JPM
Name: JPM File Format
Mime Type: image/jpm
Converter: JPM Converter
Description: The JPM file format is defined by ISO/IEC 15444-6:2003 – the JPEG 2000 image coding system – Part 6: Compound image file format. A compound image may contain scanned images, synthetic images or both, requiring a mix of continuous tone and bi-level compression methods. The JPM file format defines a composition model that describes the method of combining multiple images to generate a compound image using the multi-layer Mixed Raster Content (MRC) imaging model, defined in ITU-T T.44 | ISO/IEC 16485. - Source
