process-gmp Files

process-gmp

A very primitive converter for Garmin IMG maps, which allows you to produce a map of the same functionality but without GMP subfiles. 
The disadvantage is ~x5 map file size growth.
It's useful sometimes. For example, if you want to open a pseudo-NT IMG file with MapEdit without patching MapEdit.

Use it as follows:
1) Unpack an NT or pseudo-NT IMG file with GMapTool to folder C:\proces-gmp-input.
2) Run from the command line 
process-gmp.exe "C:\proces-gmp-input" "C:\proces-gmp-output"
3) Make sure it prints "RESULT: OK".
4) Join files from C:\proces-gmp-output with GMapTool and produce a non-NT IMG file.

The converter works as follows:
1) For every YYYYYYYY.GMP
1.1) for every XXX subfile inside YYYYYYYY.GMP
1.1.1) save a copy of YYYYYYYY.GMP as YYYYYYYY.XXX
1.1.2) replace the GMP header with XXX header in YYYYYYYY.XXX
