The low-level graphics file conversion functions used in this software are a subset of the functions in Version 2.4 of Scott Heiman's BMGLib API for reading and saving BitMapped Graphics (BMG) on the Windows operating system. Scott Heiman writes:

BMGLib uses several open source libraries that I obtained from the Internet.  ... LibJPEG is an open source JPEG file format library that is distributed by the Independent JPEG Group (IJG). LibPNG is an open source PNG file format library supported by people who wanted an alternative to GIF. Long live the rebellion! The zlib library is an open source library for file compression. It is distributed by other closely allied rebels.  ... The LibUnGIF library is Eric Raymond's response to the Unisys LZW patent.
