Title: Island Graphics TIFF tags discrepancy
Post by: jason_s on July 27, 2016, 10:52:30 AM

ExifTool (v10.24) lists the following TIFF tags:


0x80b8 [32952] => 'ImageReferencePoints',
0x80b9 [32953] => 'RegionXformTackPoint',
0x80ba [32954] => 'WarpQuadrilateral',
0x80bb [32955] => 'AffineTransformMat',

But libtiff (v4.0.6) instead says:

Code Select


#define TIFFTAG_REFPTS              32953 [0x80b9]  /* image reference points */
#define TIFFTAG_REGIONTACKPOINT     32954 [0x80ba]  /* region-xform tack point */
#define TIFFTAG_REGIONWARPCORNERS   32955 [0x80bb]  /* warp quadrilateral */
#define TIFFTAG_REGIONAFFINE        32956 [0x80bc]  /* affine transformation mat */

Somebody's off by one, but I don't know who. Which one is correct?

Thanks! ExifTool is wrong here. The good news is that these are obscure tags and probably never used by any ExifTool user

This will be fixed in the next release (10.25).
