I’m working with the examples/showCases/codesByTopic/io/loadGeomety.cpp. A new geometry.dat was made by me with a new picture. During the processing of this example, some information appeared like this:
convert: invalid pixel `./tmp/velocity031000.ppm’ @ error/pnm.c/ConstrainPixel/143.nan
And then the figures appear in the directory “tmp” were just blue or black and with nothing on them.
Could anyone please tell me how could this happen and how I can figure it out?
