[magick-users] RE: Help with syntax

[Fred Weinhaus]

Try the following and let us know if one works ( I am not too sure of 
the proper clone and delete sequences, myself). I am pretty sure the 
second one will work. Not so sure about the first and third.


convert \( src1.jpg +matte -fill "#RRGGBB" -colorize 100% \)  src1.jpg \
	-compose multiply -composite src2.png -compose atop 
-composite output.jpg

(The above probably will not work)

or

convert \( src1.jpg +matte -fill "#RRGGBB" -colorize 100% \)  src1.jpg \
	-compose multiply -composite miff: | \
	convert miff: src2.png -compose atop -composite output.jpg

(The above probably will work).

or

convert \( src1.jpg +matte -fill "#RRGGBB" -colorize 100% \)  src1.jpg \
	-compose multiply -composite \
	+clone -delete 0--2 src2.png -compose atop -composite output.jpg

(The above should work if I have the delete sequence correct).



Note you should also be able to replace src1.jpg on the right side of 
the top line of each with -clone 0

So the last one would be

convert \( src1.jpg +matte -fill "#RRGGBB" -colorize 100% \)  -clone 0 \
	-compose multiply -composite \
	+clone -delete 0--2 src2.png -compose atop -composite output.jpg
