Ftmap is available from github - it's a C program so you will need a C compiler to make it into an executable. It also uses a very old version of the gd library which is included this is used to write GIF format files. This program is old and was written before PNG became a popular format. GIF is a paletted format and limited to 256 colors.
For those without a compiler there is a windows 64bit version executable of ftmap 1.8.3. To download ignore all virus warnings as the zipfile is password protected it's safe I guarantee as I have the source code. The password for the file is ftmap
If you have problems with that then use this link to github to download the raw file. Older 32 bit binaries are here.
