Curved Drop Shadow

[mrjbar]

Hello

I'm trying to create a curved drop shadow effect with a white/transparent background similair to the photo below.



I was able to generate the following picture with this command:
convert thumb.png \( +clone -background gray -shadow 80x2+0+1 -wave -20x480 \) +swap -background white -layers merge +repage shadow.png




I can't figure out how to swap out the gray background in the picture. I woud like the background to be white/transparent.



Thanks,

try this


convert thumb.png \
\( +clone -background gray -shadow 80x2+0+1 -background none -wave -20x480 \) \
+swap -background none -layers merge +repage shadow.png
