IMAGE problems copying screen pixels

[MrZoolook]

In the Android version, I am trying to use a piece of code to scroll the entire screen up some number of pixels. I figured using the image commands would be easiest and faster. However, I can't seem to copy the area (or reprint it) exactly. It looks as if somehow, the value of each pixels red and blue componant is swapped. (screenshot included for posterity)

The code listed here should copy the 6 boxes exactly, but doesn't on all 3 Android devices I tried it on. I don't have a PC/iOS/other device to try it on. Version used is Android 0.12.11, but I've tried earlier versions to no avail.

cls
for z=0 to 255
  for t=0 to 255
    pset t+000,z,rgb(255-z,255-t,255-t)
    pset t+257,z,rgb(255-t,255-z,255-t)
    pset t+514,z,rgb(255-t,255-t,255-z)
    pset z+000,(t/4)+260,rgb(255-t,0,0)
    pset z+257,(t/4)+260,rgb(0,255-t,0)
    pset z+514,(t/4)+260,rgb(0,0,255-t)
  next
next
z=image(0,0,xmax,325)
z.show(0,350)

There is also some odd behavior when redrawing an image captured this way, if you try redisplaying it outside the screen, but apparently only in the vertical directions. My non-exhastive tests seem to indicate the horizontal placement of an image works fine.

Is this expected, or a bug?

I tried your code on the desktop version (linux) and it displays correctly so it must be an issue with android specific code. It's not expected - thanks for reporting the bug!

I will aim to include a fix in the next update.

Thank you for the update, Chris.

This issue should be resolved now, so closing it.
