I am new in Gen and the problem I try to solve is the following.

I have an incoming square video and I want to mirror the pixels of each second row.

F.i first row of pixels stays intact the second is mirrored, third is intact, fourth is mirrored and so on.

I ve been trying to get my head around working with rows using jit.pix and swiz with no success :(

Can anyone offer some help or guidance please?

I've solved my problem using standard jitter objects but I would love to see what is the equivalent in Gen.

Can anyone show me how to do the same with this patch using gen.pix?

This was a little trickier to implement than I first thought. The complicating factors were how texture coordinates in OpenGL are interpolated and dealing with floating point error.
