Hi Scott, The values make perfect sense to me. The image is 64x64 pixels, each pixel is 16 bits, so the strip size is 64*64*2 = 8192 bytes. Pixel data is split into three samples: 5, 6, and 5 bits for R, G and B. Thomas, Can you debug TIFFOpen() it and see which check fails? I expect that if you patch it, you should be able to use TIFFReadRawStrip() or maybe even TIFFReadEncodedStrip().
