I recently started working with Imagemagick and I had a problem that needs to be solved.
I have such a thumbnail.
And there is such a mask.
I need to get this image on the output.
I looked through this link http://www.imagemagick.org/Usage/thumbnails/ I tried everything there, but I did not get success ((
I hope you will help me.
This should give you a result very much like your example...
convert mask.png image.png -gravity north -composite \
mask.png -compose copyopacity -composite result.png
You can adjust the positioning of the overlay by including something like "-geometry -10+0" before the first composite.
To use this command in Windows you'll need to change that continued line backslash "\" to a caret "^".
