Dear Forums,

I am trying to create text by adding letter by letter after one another. Each letter is contained in a separate file.
Building words works, but I have problems coloring each single letter.

So for writing "AB" my imgmagick code looks similar to this:

Code: Select all

convert -gravity West -size 173x270 xc:none \
	65-1.png -geometry +10+0 +level-colors 'rgb(240,24,105)' -composite \
	66-2.png -geometry +99+0 +level-colors 'rgb(51,240,24)' -composite \
renders/output.png

I am trying to color the letter files via the "+level-colors" parameter. Unfortunately, everything is in one single color, although each line has a different RGB value. If I'm testing with "-level-colors" it has a neon look, but every letter has a different color.

I already RTFM, but apparently did not understand correctly. Please help me.
What am I doing wrong? Is there maybe another operation to achieve the effect I want?

What color are each letter and on what kind of background. +level-colors is perhaps not the best way to do that. But you need to do it inside parenthesis so that you color each image separately. can you post a link to your two A B images? If they are say white on black or white on transparent, then you can probably just use -colorize or -fill newcolor -opaque oldcolor. It is hard to tell without seeing your images, what to recommend.

Thanks, fmw42, your answer was very helpful.
The images are black to white to alpha, so they have a white "outline", which blurs to transparency. I got it working the way I wanted by putting each command into parentheses and switching from one color to two colors, which looks like this now:

Code: Select all

convert -gravity West -size 173x270 xc:none
	\( 65-1.png -geometry +10+0 +level-colors 'rgb(111,13,210)',white \) -composite 
	\( 66-1.png -geometry +99+0 +level-colors 'rgb(13,210,62)',white \) -composite 
renders/output.png

White as a second color nicely creates the outcome I wanted, but I will look into the other operations you linked as well.
Thanks again, this was truly helpful.

You do not need to specify the 'white' just the comma ',' if not given 'black' and 'white' are assumed.
Without a comma, IM thinks you want to reset all the colors in the image (change both black and white)
