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.
The CALS Raster Graphic File, having the extension .cals, is a type of image file format primarily used for the storage and exchange of digital images, especially in the context of technical and engineering documents. Developed in the mid-1980s by the United States Department of Defense, the CALS format was part of an initiative to standardize electronic document management and interchange, particularly for military and government applications.
