Hi ,

dear all,

it seems like an easy task, but i just can't find how to do it...

how can i use a image (i.e. square) as a "keyhole" mask, so that the image below the shape is seen just where the square is? and the rest is masked and invisible?

of course i can create black PNGs with a hole. but on resizing and rotation the border will show and i whould need huuuuge images to aviod that.

so i would like to have the option to "invert" the alpha on a PNG. can this be done??

thanks a lot!

i am referring to this post from 2010.

Can someone answer to this question. It would be helpful for so many tasks.

Can this be done ?

I checked the free frames but with the set I have , I canĀ“t find any way to invert the Alpha of a layer ....

And could it be done as "transfer mode" ?

This would be greate.

thanxs
