Blank/black image when streaming from TIFF64 (6.7.9-9)

Post by wildbug » 2012-10-11T09:04:28-07:00

Upon upgrading from 6.7.8-7 to 6.7.9-9 my parallel tiling script started producing black tiles. Reverting to 6.7.8-7 fixes the problem; I also installed 6.7.9-10 to confirm that it still exhibits the same issue (it does). I'm using the stream utility to read strips from very large files (usually BigTIFF) then piping to convert to tile the strip.

This is a simplified command line (the second one, of course) that still produces the problem:

Code: Select all

$ identify 27277.tiff
27277.tiff TIFF64 54018x24444 54018x24444+0+0 8-bit sRGB 3.9616GB 0.000u 0:00.000
$ stream -map rgb -storage-type char -extract 400x300+0+0 27277.tiff'[0]' - | convert -depth 8 -size 400x300 rgb:- /tmp/tiles/27277,0,0.jpg

I do not know much about bigtiff or the minimum version of libtiff that may be needed. But to verify that you have installed libtiff properly and IM actually sees it, use

convert -list configure | grep -i "delegates"

It's the stream utility, and also happens with small PNGs.

With ImageMagick-6.7.9-10:

Code: Select all

$ identify 27277-small.png 
27277-small.png PNG 844x381 844x381+0+0 8-bit DirectClass 549KB 0.000u 0:00.000
$ stream -map rgb -storage-type char -extract 400x300+0+0 27277-small.png'[0]' - | hexdump                                                      
0000000 0000 0000 0000 0000 0000 0000 0000 0000
*
0057e40
With ImageMagick-6.7.8-7 it produces the expected image of the same length (0057e40).

Were you able to duplicate this? I just downloaded svn trunk, and stream still outputs nothing but null bytes.

(As I mentioned in my second post, it's not TIFF64-specific; that was an irrelevant detail as it turns out.)

We can reproduce the problem you posted and will have a patch to fix it in ImageMagick 6.8.0-8 Beta within a few days. Thanks.
