The CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
The PDB (Palm Database ImageViewer) file extension is a format used primarily in Palm OS devices for storing bitmap images. Known also as FireViewer or TinyViewer format, it supports grayscale images with 2, 4, or 16 shades and can be uncompressed or use RLE compression. This format was integral to Palm OS applications like Image Viewer III, facilitating efficient image storage and viewing on early mobile devices.
