Pyramidal TIFF image corruption

[zanderoc]

When creating a pyramidal TIFF from an image with dimensions 1024x768 and tile size 128x128, the resulting image is corrupted.

I am using the latest ImageMagick:

Code: Select all

Version: ImageMagick 6.6.1-4 2010-04-21 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2010 ImageMagick Studio LLC
Features: OpenMP

When opening the image in GIMP, I get error messages about "Invalid tile byte count"s for different tiles.

The image was created using the following command:

Code: Select all

convert IMAGE.tif -define tiff:tile-geometry=128x128 -format tiff -compress jpeg -quality 70 ptif:IMAGE.jpg.pyr.tif

This does also happen when the image is not compressed. Larger images (>4k x 4k) did convert fine to the pyramidal TIFF.

We'll investigate this problem and apply a patch to ImageMagick 6.6.1-5 Beta within a few days. Thanks.
