Blank/black image when streaming from TIFF64 (6.7.9-9)
Posted: 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:
On Gentoo Linux amd64.
What else can I provide?
