Hi!

Im working with C++ & win API32.

My Problem:

  I have in a matrix of unsigned chars the colours (in RGB format) of
an image. The dimensions of the image are 720 x 576 (cols x rows). So
the size of the matrix is 720*576*3 bytes (unsigned chars).

  My pogram has to show that image in the Main Window. But I don't
know how show i efficiently. By now, I have one SetPixel(...) function
for every pixel :D so it is not "immediately" and you can see how the
image "grows up" :( How can I show the total image with one function
call? BitBlt() is the solution? Using BitBlt() I dont know what is
"handle to source DC" in front of my data image matrix.

Thanks a lot! ;)
