problem with -fx
Posted: 2009-09-21T05:55:29-07:00
Hi all!
I'm quite new to ImageMagick. I try to remove tints from some pictures, using the fx-operator. Unfortuantely, the code given in the color-modification-exampled gives the following error message:
'u' should be test.png, which exists in my working directory, or am i mistaken?
This example works fine:
I use Windows Vista's console and ImageMagick-6.5.6-2-Q16-windows-static.exe.
Can you give me any hints of what I may be doing wrong?
Thanks from Germany,
Markus
