Hi: gurus I am trying to parse the metadata of a tiff file using the identify -verbose option for a tiff file. But one thing I have noticed that the verbose command don't spit any tiles info. I guess my question is that is there any way I can get tile information via the verbose command. Besides this is there any way you can get the info about the single vs multiple strip via verbose command.
Regards,
RJ.

Re: identify verbose doesn't show the tile info in a tiff fi
Can you post a link to one of your tiled tiff files?
In the meantime see the -defines for tiff at http://www.imagemagick.org/script/formats.php and http://www.imagemagick.org/script/comma ... php#define
testing -- shows each resolution for a pyramid tiff as a layer and shows the rows per strip as tiff:rows-per-strip: 16
I am puzzled by the size of the last resolution layer. I assumed it created the last resolution to fit to one tile or smaller rather than pad to a full tile. Thus the last layer is 50x37 and not 128x128. But a factor of two larger would be 100x74, which would still fit into one tile of size 128x128. I don't understand this and may be a bug. Perhaps some one can clarify if I have made a bad assumption. Does IM always create 6 resolution levels regardless of the tile size? Is there a define for how many resolution layers to create?
It does not seem to show the number of tiles per layer though nor the tile size.
convert barns_grand_tetons.jpg -define tiff:tile-geometry=128x128 PTIF:barn_test2.tiff
c-98-234-221-122:images fred$ idv barn_test2.tiff
That data is available in the EXIF information via EXIFTOOL as:
322 TileWidth : 128
323 TileLength : 128
Perhaps that could be added to the IM verbose information and the string formats
exiftool -s -ee -g1 -u -n -D barn_test2.tiff[/quote]
I would suggest you post a new topic on the Developers forum and request the addition of the tile data and put a link back to this discussion.

I would suggest you post a new topic on the Developers forum and request the addition of the tile data and put a link back to this discussion.

Re: identify verbose doesn't show the tile info in a tiff fi
You can also use tiffinfo to get that information:
convert barns_grand_tetons.jpg -define tiff:tile-geometry=128x128 PTIF:barn_test2.tiff
tiffinfo barn_test2.tiff
Namely,
Tile Width: 128 Tile Length: 128
Rows/Strip: 16
Page Number: 0-6 (I believe this means that there are 6 resolution levels written as layers and numbered 0-5, since IM and Tiffinfo show those layer numbers and 6 layers in subsequent information listed out not included here)
It would be nice if IM would show the tile dimensions in its verbose tiff information.
