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 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 this file format, LEAD supports CCITT, G3(1D, 2D), CCIT G4, ABIC, and IBM MMR compression. LEAD does not support RL4, and Color Compression used by OS/2.
LEAD supports loading and saving multi-page files in this format.
File constants associated with this file format are:
