Convert CALS to FPX

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 FPX file extension stands for FlashPix Format, a bitmap image format developed in 1996 by Kodak, Microsoft, Hewlett-Packard, and Live Picture. It was designed to handle large image files efficiently by storing images at multiple resolutions within a single file, allowing quick access to the appropriate resolution based on display requirements. FlashPix uses Microsoft's structured storage format, which organizes hierarchical data in a single file. This format was particularly useful for digital photography and imaging applications, optimizing storage and bandwidth usage.
