OGR GMT layer: wrong extent identification

[peifer]

The extent of my sample gmt file is: # @R-4/-3.9/37/37.1 However, ogrinfo reports:
Extent: (4.000000, 37.000000) - (-3.900000, 37.100000).

The first character is obviously swallowed when reading the gmt header. I changed line 183 in ogrgmtlayer.cpp which seems to help:

 // char **papszTokens = CSLTokenizeStringComplex( osRegion.c_str() + 1,
    char **papszTokens = CSLTokenizeStringComplex( osRegion.c_str() + 0,

The sample GMT file is attached.

Another sample GMT file

I attach another sample file (grid2.gmt) where the actual extent of # @R900000/1000000/900000/1000000 is reported to be Extent: (0.000000, 900000.000000) - (1000000.000000, 1000000.000000).

Applied, thanks
