- Description
- The CALS raster file format, commonly known by the extension ".cal" or ".cals," is a bitmap file format designed primarily for the storage and interchange of digital images, especially in the field of computer-aided design (CAD) and engineering. Developed by the United States Department of Defense, it was intended to standardize the exchange of graphics data for electronic publishing of technical manuals. This format supports monochrome (1-bit) images and is distinguished by its efficient compression methods for reducing file sizes, facilitating easier storage and transmission. Despite its specific initial use case, the CALS raster format has found application in various industries for the archiving and sharing of high-resolution, scanned documents.
- A TGA file is a file saved in the raster graphic format designed by Truevision. It supports 8, 16, 24, or 32 bits per pixel at a maximum of 24 bits for RGB colors and and 8-bit alpha channel. TGA files are often used to store texture files referenced by 3D video games.
