[Insight-users] problem in reading and writing an image file

[john smith]

Well,
I made the changes in the directory file but there are still some problems
in the command prompt window:
1) When I am trying to convert a inputfile.jpg to an outputfile.png, then I
get the .png file but I cannot see anything as it is a black screen
2) When I am trying to convert a inputfile.jpg to an outputfile.jpg, then I
have again an exception caught, which says that JPEG supports unsigned
char/int only

Could somebody explain me why I face these two problems? Using an
itk::CastImageFilter<> or an itk::RescaleIntensityImageFilter<> would
propably solve this problem?

Thanks in advance
