Unless the question is about decoding a (gif, png, jpg etc)
into a bitmap, in which case the right answer is probably

tv,reverse(ret),tru=1
(hard to help out when I don't really know what the question
is asking...)

If I understand the questions right, then it was just
answered in the forums:
GDL> tvscl,findgen(200,200),channel=1
GDL> tvscl,transpose(findgen(200,200)),channel=2
etc,etc ...

without number, gives a list
then, e.g. : TVSCL, DIST(128)
