so nice .
exactly a good starting point for me .
simple and efficient.
you made it specially for me ? :-)

i'm trying to learn some glsl and i am not really fluent in it for the moment.
to say the less.
but reading your code makes me willing to try things.

Thanks

Thanks for your help.

i would like to output a pix with this transformation,with image wrapping around ,
so shearXY is not very practical in my situation.

i would prefer to avoid using pix_snap too.

i need it to be quite fast, working on a live 25 fps 720*576(cropped to square) video feed.

any other otions?

would a GLSL shader do it ?

look at the attached shader, maybe it does what you want?
