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 single and multi-page files in a MO:DCA wrapper with embedded 1-bit CCITT, Group 3 or Group 4 images, IBM MMR and uncompressed IOCA. LEAD also supports IOCA files without the MO:DCA wrapper. LEAD 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 this file format, LEAD supports CCITT, G3(1D, 2D), CCIT G4, and IBM MMR compression. LEAD does not support RL4, and Color Compression used by OS/2.

LEAD supports saving multi-page files in this format.

File constants associated with this file format are:

Constant	Write Support	Description
FILE_ICA_G3_1D	1 BPP	[71] IOCA, compressed using CCITT group 3, 1 dimension.
FILE_ICA_G3_2D	1 BPP	[72] IOCA, compressed using CCITT group 3, 2 dimensions.
FILE_ICA_G4	1 BPP	[73] IOCA, compressed using CCITT group 4.
FILE_ICA_IBM_MMR	1 BPP	[117] IOCA, compressed using IBM MMR, with the MO:DCA wrapper.
FILE_ICA_UNCOMPRESSED	1 BPP	[253] IOCA, uncompressed, with the MO:DCA wrapper.
FILE_RAWICA_G3_1D	1 BPP	[77] IOCA, compressed using CCITT group 3, 1 dimension, without the MO:DCA wrapper.
FILE_RAWICA_G3_2D	1 BPP	[78] IOCA, compressed using CCITT group 3, 2 dimensions, without the MO:DCA wrapper.
FILE_RAWICA_G4	1 BPP	[79] IOCA, compressed using CCITT group 4, without the MO:DCA wrapper.
FILE_RAWICA_IBM_MMR	1 BPP	[118] IOCA, compressed using IBM MMR, without the MO:DCA wrapper.
FILE_RAWICA_UNCOMPRESSED	1 BPP	[254] IOCA, uncompressed, without the MO:DCA wrapper.
