FAQ
CT1 to CG4 Conversion
What are CT1 files?
CT1 is a raster image file extension used for CALS Type 1 files, defined by the U.S. Department of Defense Computer-aided Acquisition and Logistic Support (CALS) initiative in the MIL-R-28002 specification, and later incorporated into MIL-STD-1840 for the exchange of technical documentation. A file of this type contains a single black-and-white page, stored as a bilevel image compressed with the CCITT Group 4 (ITU-T T.6) method, which made it well suited to scanned engineering drawings, manuals, and archival paper documents. The page is preceded by a fixed-length text header that identifies the source document, the figure, the document class, the pixel dimensions, the page orientation, and the scanning density. The format supports no color or grayscale, and remains in use in legacy technical document archives.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
