Using 4.0.3a under OSX 10.6.3 with XQuartz 2.3.5
I have two XTC files (one attached). As recent as yesterday, I could successfully Export to Bitmap to generate an XPM file that could be imported by GIMP for conversion or whatever. Yesterday evening I modified jazzbass_2.xtc by adding some structures and adding/modifying some filled polygons and rectangles. I tried to export. XTrackCAD gave no error. GIMP claims the XPM file is invalid.
I tested against a second file, musicman.xtc, which has NOT been modified since the last time I generated a valid XPM file from it. It, too, now generates an invalid XPM file.
I created a brand new, simple file with only a circle of Atlas 9.75" curve track segments. This export DID create a valid XPM file.
Not sure what the problem is. Appreciate any help. Will run whatever tests you like, but I haven't figured out how to compile source yet...
