- Description
- 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.
- A JP2 file is a compressed bitmap image created using JPEG 2000 Core Coding. It incorporates a wavelet compression algorithm instead of Digital Cosine Transform (DCT) compression, which is used by standard JPEG images. JP2 files can be stored using lossy and lossless compression.
