File Formats: 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 multipage files in a MO:DCA wrapper with embedded 1-bit CCITT, Group 3 or Group 4 images, IBM MMR and uncompressed IOCA. LEADTOOLS also supports IOCA files without the MO:DCA wrapper. LEADTOOLS loads and saves all these formats. LEADTOOLS can read and write 1-bit and 1-bit / 4-bit ICA images.

The default extension used by this format is: ICA.

This file format does not support stamps or Lossless JPEG compression, but it does support multipage 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 loading and saving multipage files in this format.
