I have a window that I want to draw a picture on (w/o DX). I read the image from a file with the following format: 2-bytes Height 2-bytes Width 4-bytes RGBQuad(Red,Green,Blue,Alpa) (Transparency Color) ...-bytes Image data (Height*Width*4) Is there a way to draw this image to a window without plotting each individual pixel? If so, how? I''m not so worried about Pixel Format because I understand how to check that. Thanks, Jumpster

Hi
This is what i usualy do. i write my graphics/game programs
with GDI coz it is easier to implement and debug, finaly i do
convert the whole stuff using my directx libs.
There are two major ways to draw bitmaps in windows API.
One is easier to access the pixel data : DIB Images (Device Independent Bitmaps) which can be in several color depths,
and can be shown using the StretchDIBits api function, screen
color depth doesn''t matter coz StretchDIBits does the proper
conversion for you. Transparency is NOT supported by these kind
of images.
Another way is using the windows bitmap objects, but they need
more work to obtain direct access to the pixel data, Blt and
StretchBlt functions are used to copy them onto screen,
transparency is not handled easily until Windows 98 in which
you have the TransparentBlt function.
