jit.alphablend and jit.matrix


I’m using some 120 x 120 px PNG images (with transparency) that I’m trying to composite together. I read the image according to a key pressed, send it to alphablend to get rid of the alpha then to a matrix to position the resulting image using the destdim arguments.

I can position the images or get rid of the alpha but I can’t do both… Would anyone have a suggestion ?

Here is the patch and I have also attached three images that can be triggered by the letters A B C (ASCII 97,98, 99). Thanks !

Have you considered the use of the trigger object to control the order of operations? That’s always a good idea when you’re interested organized sequences of more than one thing.

Well, rather than processing the image’s alpha first then placing it in another matrix, I have done the opposite and it works ! I have put the working code if anyone is interested using it or simply comment on it !
