JEDMICS C4 Compressed Image

You can view JEDMICS C4 Compressed Image (.c4) files.

These are raster (bitmap) image formats developed by the US DoD (Dept. of Defense) for military use.

The JEDMICS C4 compressed image file is very similar in structure to the TIFF 6.0 tiled file format and the TG4 file format. These three file formats differ only in the structure of the header and tile indices. All three file types use CCITT Group 4 encoding, and the structure of the compressed tiles is the same for all three.

Each .c4 image file is capable of storing a single black and white image. It has no capability to store color or grayscale information.
