What is an .ODA file?

.ODA is CALS Group IV type 2 raster image

The oda file extension is associated with the CALS Group IV type 2 raster image file format.

CALS files are used for document imaging and therefore only store black-and-white, 1-bit image data.

CALS Type I files only store a single image per file and the data is always compressed using the CCITT Group 4 encoding algorithm.

CALS Type II files may stored multiple images per file, the image data may be tiled, and tiles stored as raw data or as data compressed using CCITT Group 4 encoding.


How to open:

Use XnView to view content of *.oda files.

How to convert:

XnView is able to export *.oda files to other picture formats.
