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:
$ 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)
Compression Scheme: JPEG
Photometric Interpretation: YCbCr
YCbCr Subsampling: 2, 2
Planar Configuration: single image plane
I get the same problem with TIFFs that aren't tiled or multi-image.
Any help is appreciated.
