- 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 PAT file format is a pattern file used by CorelDRAW, a vector graphics editor developed by Corel Corporation. It contains patterns that can be applied to fills, outlines, and textures within graphic projects to enhance visual appearance and add complexity to designs. These patterns range from simple geometric designs to more intricate images, allowing users to apply textures and motifs seamlessly across their artwork. PAT files are utilized to store and share custom patterns, facilitating consistency and creativity in graphic design projects.
