I have this command's:
composite -compose Multiply "b.png" "p4.png" "p0.png"
composite -compose Multiply "y.png" -negate "p4.png" "p1.png"
composite -compose Plus "p0.png" "p1.png" "final.png"
used one after one it generates my needed image, but I only need final.png. p0,p1 are not needed. How to join into one line these commands ?
I tried:
convert "b.png" "y.png" "p4.png" \
\( -clone 2 -negate \) \
\( -clone 0,2 -compose Multiply \) \
\( -clone 1,3 -compose Multiply \) \
\( -clone 4,5 -compose Plus \) \
\final.png
I use:
ImageMagick 6.8.9-9 Q16 x86_64 2018-09-28

Reverse the order of your pairs of images when using convert. See
https://imagemagick.org/Usage/compose/#compose. Also why is there a \ before final.png?
If that does not help, then post your images to some free hosting service that won't change the format and put the URLs here.

https://i.ibb.co/Wc0P92h/B.png <- B image
https://i.ibb.co/JvYYkw6/Y.png <- Y image
https://i.ibb.co/2t0M5t0/p4.png <- p4 image (grayscale mask)
https://i.ibb.co/NTz7jkr/final.png <- Wanted Result
I tried changing the order and removed before final "/", but I don't know if I understood it right:
convert "b.png" "y.png" "p4.png" \
\( -clone 2 -negate \) \
\( -clone 2,0 -compose Multiply \) \
\( -clone 3,1 -compose Multiply \) \
\( -clone 5,4 -compose Plus \) \
final.png
but i get error :"(: command not found" on ubuntu

The \ character means "the command continues on the next line" only when it is the final character of the line. Don't have a space after it.

there is no more error with "\", thanks.
but it produces 9 images(final33-0 to 9) and none of them is like my wanted result. what can I do now ?

"-compose X" is a setting that is used by some operators such as "-composite". So replace "-compose Multiply" with "-compose Multiply -composite", etc.

thanks, now it works 100%! Great Forum!
convert "b.png" "y.png" "p4.png" \
\( -clone 2 -negate \) \
\( -clone 0,2 -compose Multiply -composite \) \
\( -clone 1,3 -compose Multiply -composite \) \
\( -clone 4,5 -compose Plus -composite \) \
-delete 0-5 final99.png

try this
Code: Select all
convert b.png p4.png \
\( -clone 0,1 -compose multiply -composite \) \
\( y.png -negate -clone 1 -compose multiply -composite \) \
-delete 0,1 \
-compose plus -composite \
final.png

thanks fmw42, for Your reply, but this is not using "y.png"(Yellow). I mean the result is only black and blue.
https://i.ibb.co/r3W0f1f/final4.png
For now I have:
convert "b.png" "y.png" "p4.png" \
\( -clone 2 -negate \) \
\( -clone 0,2 -compose Multiply -composite \) \
\( -clone 1,3 -compose Multiply -composite \) \
\( -clone 4,5 -compose Plus -composite \) \
\( -clone 6,0 -compose CopyOpacity -composite \) \#I also needed to add this line because it happens that the alpha channel went everywhere 255, what was not intended.
-delete 0-6 final88.png
If there is an more elegant solution fmw42 please let me know.

See my line
Code: Select all
\( y.png -negate -clone 1 -compose multiply -composite \) \
But my code was not tested. So I could have made a mistake. Your code should be able to reduce the number of images you keep around in memory.

This seems to work for me to reproduce your final image.
Code: Select all
convert p4.png \
\( -clone 0 b.png -compose multiply -composite +write fred_p0.png \) \
\( -clone 0 -negate y.png -compose multiply -composite +write fred_p1.png \) \
-delete 0 \
-compose plus -composite \
fred_final.png

Yes this new ones works, thanks. so which one should I use in my application? which one is better? I mean Yours produce two more images, but deletes only 1, mine produces only one final. so i is my better?

I forgot to remove the extra writes that I used for testing. Use the following:
Code: Select all
convert p4.png \
\( -clone 0 b.png -compose multiply -composite \) \
\( -clone 0 -negate y.png -compose multiply -composite \) \
-delete 0 \
-compose plus -composite \
final.png
