Image Object Content Architecture Format (IOCA/MODCA)

The Image Object Content Architecture format was developed by IBM. This architecture provides a consistent way to represent images, including conventions and directions for processing and interchanging image information. LEADTOOLS supports 3 types of IOCA files:

  1. Raw IOCA files. These files use the FILE_RAWICA_XXX defines. These files are single IOCA images and do not have the MO:DCA wrapper.

  2. MO:DCA IOCA files. These files use the FILE_ICA_XXX defines. These files can be multipage and have the MO:DCA wrapper around the IOCA image.

  3. AFP MO:DCA IOCA files. These files use the FILE_AFPICA_XXX defines. These files can be multipage and have the MO:DCA wrapper around the IOCA image prefixed with AFP.

LEADTOOLS supports the following 1-bit compressions: Fax Group 3 or Group 4 images, IBM MMR (Fax G3 1D without EOL), uncompressed and ABIC. LEADTOOLS also supports 4-bit files with ABIC compression only. LEAD loads and saves all these formats.

The default extension used by this format is: ICA.

This file format does not support stamps or Lossless JPEG compression, but it does support multi-page files for the MO:DCA files. LEAD does not support RLE4, Color Compression used by OS/2 and JPEG compression.

File constants associated with this file format are:
