Hi,
The background of pic1.png has been cleared (using gimp). After the
following command (to produce the sketch effect), the cleared background
shows up again in pic1.gif. I'm wondering why the cleared background can
still managed to show up, and how can I fix the problem.
convert pic1.png \( +clone -median 2 -blur 0x7 -negate \) \
-matte -channel A -evaluate set 50% -compose plus -composite pic1.gif
Here are the picture and the result.

I've also tried to specify -channel RGBA, but the result is all grayed.
convert pic1.png \( +clone -median 2 -blur 0x7 -negate \) \
-matte -channel RGBA -evaluate set 50% -compose plus -composite pic1.gif
Please help
thanks
