I've run into a problem with resizing a CMYK TIFF file with an alpha channel. IM v6.3.4 works great, but when I try to use the latest version 6.5.6-10 problems result. The K channel gets cleared out. The files I'm using are:

http://www.extremevisionproducts.com/IM/Logo.tif (original)
http://www.extremevisionproducts.com/IM/IM_6.3.4.tif (6.3.4 result)
http://www.extremevisionproducts.com/IM/IM-6.5.6-10.tif (6.5.6-10 result)

The command I'm using is:

convert Logo.tif -resize 100 IM_x.x.x.tif

Do I now need additional variables in the command line to protect the file structure?

Thanks!!!

We can reproduce the problem you reported and have a patch in ImageMagick 6.5.7-0 Beta. Look for it at ftp://ftp.imagemagick.org/pub/ImageMagick/beta by sometime tomorrow. Thanks.

Thanks for the fix!!!
