==File Information==
'''PDG''' files are proprietary and normally contain raster data, but can also contain text. Compression is usually [[CCITT_Group_4|CCITT]], [[DjVu]], [[PNG]], and [[JPG]]. '''PDG''' files generally have a 140 byte header which begins with hex values "{{magic|484802}}", followed by a byte indicating compression. This is also referenced at byte "0xE", with the next byte, "0xF" being the "version" of the PDG file.<ref>https://www.cnblogs.com/stronghorse/p/4913305.html</ref><ref>https://www.cnblogs.com/stronghorse/p/4913239.html</ref>
