Composite - how to make overlay semi-transparent?

[walsi]

Hi,

I want to 'merge' to pictures - a map and an overlay... it does work perfectly with

composite img1.png img2.png new.png

But now I'd like to have the overlay semi-transparent, so the map shines through a little bit - how can I do that?

Thank you very much for your help!

You could try blend:

Code: Select all

composite -blend 90 img1.png img2.png new.png
