| Fl_RGB_Image::copy(int W, int H) has a severe error:
when creating an equally-sized copy, the value of ld() is ignored (Fl_RGB_Image.cxx:158):
new_array = new uchar[w() * h() * d()];
memcpy(new_array, array, w() * h() * d());
resulting in an uncomplete copy of the data (if ld() > w()) The best solution would be to check for w()!=ld() and doing a line-wise copy in that case. Copying the complete image with ld()*h()*d() is a bad idea since sometimes ld() > w() is used to reference only parts of a huge image and we don't want to copy that much data. In my case ld()=1024 and w() is approx. 100. | |
