The Mixed Raster Content format was defined for use of color and grayscale fax as part of the RFC-2301, File Format for Internet Fax. The Mixed Raster Content mode (T.44) enables different coding methods and resolutions to be used within a single page by defining a 3-layer image model for structuring and combining the scanned image data. The image is segmented and each segment assigned a type based on the number of colors used in that segment. Segments can be combined and compressed using different compression schemes to create a file that balances quality with compression.
The default extension used by this format is: MRC.
LEADTOOLS supports Load and save for this format.
Keys that must be unlocked to enable this format support:
Multi-page is supported through TIFF format.
File constants associated with this file format are:
| Constant | Read Support | Write Support | Description |
| Mrc | 24 BPP | N/A (see note below) | Mixed Raster Content. |
NOTE: MRC is made up of different segments, which can be of various BitsPerPixel. When you request file information on an MRC file, it will be reported as 24-bit. When you save MRC files, various segments will be saved with different BitsPerPixel, based on the content.
