i'm trying to fix the fluxus invaders script to work with the flipped textures and encountered a problem. because the png is flipped while read, the pdata does not start from the top-left corner anymore. for example, i use load-primitive to load a png file to a pixels primitive. if i use (pdata-set! "c" 0 (vector 1 0 0)), i set the first pixel of the last line, not the first pixel of the first line.
best, gabor
