\( +clone -monochrome \) does not respect parenthesis

[bablokb]

Hi,

I want to create a preview of the original image together with a monochrome-version:

convert myimage.jpg \( +clone -monochrome \) -append out.jpg

The result is that both images are monochrome. In contrast the (pseudo) b&w-version:

convert myimage.jpg \( +clone -modulate 100,0 \) -append out.jpg

works as expected (i.e. the operator operates only on the image-stack within the parenthesis).

identify -version: Version: ImageMagick 6.2.5 05/02/06 Q16 http://www.imagemagick.org
OS: Linux, OpenSUSE 10.1

It worked fine for me with the latest IM. You may have hit an old bug that has since been long fixed.

Code: Select all

   convert rose: \( +clone -monochrome \) -append x:
