Hi!

I'm an IM noob, I went though all the docs and just can't find a way how to solve my problem. I have an image like this http://www.hey.si/slika.jpg, which will serve me as a background of another image http://www.hey.si/ura.jpg. I want the end image to look like this . What are the steps I should take to achieve this ? Before I only used IM for converting and resizing, but now I have this complicated problem. Please help, thank you !

try the following

you have to resize the big image to the size of the small image, you have to create as grayscale mask from the small image and invert (-negate) the black and white, and flood fill the outside of the mask with white. Then you delete the big image and composite the others together.



dim=`convert ura.jpg -format "%wx%h" info:`
convert slika.jpg ura.jpg \
\( -clone 0 -resize $dim! \) \
\( -clone 1 -colorspace gray -negate -fuzz 10% -fill white -draw "color 0,0 floodfill" \) \
-delete 0 -swap 0,1 -compose over -composite result.jpg

Actually, the above still needs a little work as the numerals are not outlined. I will try to fix this later, though not sure exactly when. So anyone else is welcome to improve it.
