I think you are confusing REBIN with the similar sounding,
but different, REFORM. Making the switch makes your test
program work:
pro test
window,5,xsize= 128, ysize = 128
window,6,xsize= 128, ysize = 128
at_target= bytarr(64,64)
at_target(0:63,0:63) = 255B
at_target(10:20,10:20) = 200B;
wset,5
tvscl, at_target
wset,6
tvscl, Reform(Reform(at_target, 64*64),64,64)
end
Cheers,
David
