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 for WPF 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. LEADTOOLS for WPF also supports IOCA files without the MO:DCA wrapper. LEADTOOLS for WPF loads and saves all these formats. LEADTOOLS for WPF 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 multi-page files. For this file format, LEADTOOLS for WPF supports CCITT, G3(1D, 2D), CCIT G4, and IBM MMR compression. LEADTOOLS for WPF does not support RL4, and Color Compression used by OS/2.

LEADTOOLS for WPF supports loading and saving multi-page files in this format.
