Convert DCX to CALS

The DCX file extension, standing for ZSoft Multi-page Paintbrush Image, is a raster image format developed by ZSoft Corporation. It is primarily used for creating multi-page digital fax files, containing a sequence of PCX images. Each DCX file begins with a small header identifying the file, followed by multiple embedded PCX files. This format was widely adopted in early digital faxing and document imaging applications due to its ability to handle multiple pages within a single file.

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.
