== Overview ==
'''CALS raster''' is a group of image file formats associated with the U.S. Department of Defense.

CALS stands for '''Continuous Acquisition and Life-cycle Support''' (new name), or '''Computer Aided Acquisition and Logistics Support''' (old name).

== Format ==
There are two main formats, and at least two more that have also been placed under the CALS umbrella.

=== Type 1 ===
* Description: Untiled
* Filename extension: .ct1 (MIL-PRF-28002C), .cal (MIL-PRF-28002B)

Type 1 files have a 2048-byte ASCII header, consisting of up to 16 128-byte header fields.

Bi-level image data follows, which always uses [[CCITT Group 4]] compression.

There are two versions of Type 1 format: one defined in MIL-PRF-28002B, and one defined in MIL-PRF-28002C.

=== Type 2 ===
* Description: Office Document Architecture (ODA) Raster Document Appilcation Profile (DAP) Tiled/Untiled
* Filename extension: .ct2

Type 2 is a more complex format, which adds support for multiple images, uncompressed images, and other things.

=== Type 3 ===
* Filename extension: .ct3, .nif
* Description: Navy Image File Format (NIFF) Tiled/Untiled

=== Type 4 ===
* Description: JEDMICS C4 Tiled
* Filename extension: .ct4, .c4

See [[JEDMICS C4]].

== Identification ==
Type 1 files most likely start with ASCII string "<code>srcdocid:</code>", "<code>rorient:</code>", or "<code>version: MIL-STD-1840</code>".
