FAQ
SIG to CG4 Conversion
What are SIG files?
SIG is a raster image format used to store a handwritten signature as a picture, so that it can be placed on documents, forms, and letters in place of a pen signature. A file of this type holds a single bitmap, usually a scan, a photograph, or a capture from a signature pad, and carries no layers, no text, and no vector strokes. Signature images are normally small, often a few hundred pixels wide, with a white or transparent background and dark ink. The data is compressed JPEG, and some systems that produce the files, typically document management and e-signature software, store it in a modified byte order. For that reason, a generic image viewer may not recognize a .sig file until its contents are converted.
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.
