I am opening 16 bit 3 channel TIFFS with OpenImageIO to calculate values on the
pixels. I perform some logic to grab matting information and I noticed that
when I open little endian files and save them out using OpenImageIO, the images
appear to be flipped around the x axis. This does not happen when working with
Big Endian TIFF files. The images appear upside down. Here is my very
rudimentary code to open the files. If I save this file out, then it is flipped.
Patrick
ImageInput *in = ImageInput::open (argv[1]);
if (!in)
return -1;
const ImageSpec &spec = in->spec();
int xres = spec.width;
int yres = spec.height;
int channels = spec.nchannels;
std::vector<float> pixels (xres*yres*channels*sizeof(float));
in->read_image (TypeDesc::FLOAT, &pixels[0]);
