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().

Look at the various tag values, they don't make sense: ImageLength, BitsPerSample, SamplesPerPixel, RowsPerStrip, StripByteCounts.

I expect you'd really have to patch up the directory to have any hope of reading this file.
