Using TIFFReadEncodedTile, I was able to decode all 7 images in the sample file without any errors.

The TIFF library runs into an internal problem when I try to use it to read

YCbCr JPEG-compressed images. I'm currently using version 4.0.0beta6,

but 3.9 and 3.7 had the same problem. Calling TIFFReadTile() inside my

program for the first tile produces the following error:

JPEGDecodeRaw: application buffer not large enough for all data.

I have put a sample image (it's 41 MB) at:

http://csbruce.com/temp/q09050_006_nir.tif

$ tiffinfo q09050_006_nir.tif
TIFF Directory at offset 0x2705581
  Image Width: 11500 Image Length: 7500
  Tile Width: 256 Tile Length: 256
  Resolution: 0, 0 (unitless)

Bits/Sample: 8

Compression Scheme: JPEG

Photometric Interpretation: YCbCr
YCbCr Subsampling: 2, 2

Samples/Pixel: 3
  Planar Configuration: single image plane

I get the same problem with TIFFs that aren't tiled or multi-image.

Any help is appreciated.
