Hi,
I also have the same problem i.e. doing pixel drawing
by default routine result unsatisfied.
1. what do you mean 'direct pixel access'? how to work
with that?
2. currently i also have problem with coloring. How to
create colortable to BitmapType (bitmaptype was
created by code)?
I try this way:
a. Create BitmapType* with colortable = NULL
b. create winoffscreen to wrap it and set is as
active draw Window
c. assign color 'WinSetForeColor' or
'WinSetForeColorRGB' then draw/paint pixel
d. The result...the color doenst match and
However, the performance of using draw pixel/paint
pixels is very slow....dont know yet how to achieve
it.
please help.
Please advice. thanks
Peter
