- 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.
- PCX, standing for Paintbrush Bitmap Image, is a raster image format developed by ZSoft Corporation for their PC Paintbrush graphics program. Initially released in the 1980s, PCX was one of the first widely used bitmap image formats on IBM PC compatible computers. The format supports 1-bit monochrome, 4-bit palette, 8-bit palette, and 24-bit true color images, allowing for a wide range of colors and shades.
