What's a good way to flip (top to bottom) or mirror (left to right) a Jitter matrix?

I've grown used to using OpenGL for display, in which case I use a @scale -1 type construct, but in this particular case I am using all Jitter matrices.

[jit.dimmap] should do what you need, with combinations of "invert" and "map" commands. the "map" commands will flip the X Y dimensions, so use the [fpsgui] and check the outcoming dimensions to be sure it's doing what you want.

FWIW it is also possible to flip a matrix with the srcdimstart, srcdimend and usedstdim attributes (or the destination equivalents). (see Jitter Tutorial 14 for clues)

can you flip it in openGL? Some shader maybe?

you can add to inlet the object [ pak invert 0 0 ] with two toggles as well

[  dimmap @0 1 ]   to flip it like a mirror
