Hi Ulrich,the reason of the problem is not image or cimage. yes you are
right they are different but i think i wrote it wrong here.
anyway when i debug i saw that cImage resoultion did not change.
but today i checked the code again and i saw that i wrote the code like:
cImage->scaleImage(image->s() * scaleFactor, image->t() *
scaleFactor, image->r() * scaleFactor);
scaling of first 2 is ok but not the third one. image->r() should not be
changed. so i corrected like that:
cImage->scaleImage(image->s() * scaleFactor, image->t() *
scaleFactor, image->r() );
now it works... :)
