- I have been trying to integrate YCbCr TIFF support into my project by
- using libtiff and I ran into some inconsistencies between the spec and
- libtiff (this may be the fault of my erroneous interpretation of the
- spec, in which case I need to be corrected.)
-
- 1. According to the spec, BitsPerSample (quoting from memory) is supposed
- to be an array sized by the sample count to allow different number
- of bits per sample (e.g. R,G,B = 5,6,5 bits respectively.) Libtiff
- always treats BitsPerSample as a single quantity. Is libtiff somehow
- "normalizing" the BitsPerSample to the greatest element of that array?
-
- 2. YCbCr files cannot be read by scanlines, but reading by strips works
- as expected. However, in libtiff there is no way to specify which
- particular sample to load if PlanarConfiguration is 2. Or is there?
- Tile-based YCbCr files should work, but I have no files in that format.
-
- 3. Has anyone integrated JPEG support by using jpeglib?
