I am trying to write some pixels on an imagebuffer, but i would like to "write" transparent pixels. I can't seem to reproduce the effect, but it worked several times, and I don't remenber how to do it ...
It was working with:
setbuffer imagebuffer(myimage)
color r,g,b
plot x,y
setbuffer backbuffer()
is there a "special value to set r,g,b to, to have transparent pixels?
