Hi!
Does Gfxprim handle BigTiff images;i.e., libtiff v4.x and greater? If so can spiv show BigTiff images?
BigTiff allows tiff files to be up to 2 to power of 64 minus one in size.
I haven't tried to work with BigTiff images so there may be other problems that I cannot foresee, but primarily GFXprim has two limitations. Currently whole image is loaded into memory when image is loaded from a file (you cannot work with single tile or stripe yet) and the image width and height is limited to 32 bit unsigned.
