- 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.
- The WBMP (Wireless Bitmap Image) file format is a monochrome graphics format optimized for mobile computing devices with limited display capabilities. It was developed for use in the early days of mobile internet to display images on mobile phones and other wireless devices with minimal processing power and storage. WBMP files contain bitmap images that are typically small and use a black and white color palette, making them highly efficient for fast loading times and minimal data usage.
