Mixed Raster Content (MRC) - Raster Imaging C API Help

Mixed Raster Content (MRC)

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.
