The GP4 file type is primarily associated with CALS Raster, a standardized image file format used for the interchange of graphics data. It is specifically used for the storage of monochrome images and is often utilized in the fields of engineering, manufacturing, and government sectors, particularly for technical documents and drawings. The GP4 format is part of the CALS (Continuous Acquisition and Life-cycle Support) initiative, which aims to improve the efficiency of acquiring and managing resources in these sectors. This file type supports high-quality scanned images and is designed for electronic storage and transmission.
Image stored in the JPEG XR format, which was originally developed by Microsoft for Windows Media software; supports deep color images with 48-bit RGB; used for high-resolution professional image editing; also supports lossless and lossy compression.
