Pixel plotting
February 15, 2002 11:02 AM
I have been learning the basics of windows programming for a while now and would now like to learn a bit about GDI, such as plotting pixels on screen. So can anyone please give me an idea on how to create a simple function that plots a pixel,
somthing like -
Pixel(x, y, color, hwnd);
This is probably overly simple, but it looks like a good way.
Thanks for your time.

Sounds like you are looking for the SetPixel() function:
COLORREF SetPixel(
HDC hdc, // handle to DC
int X, // x-coordinate of pixel
int Y, // y-coordinate of pixel
COLORREF crColor // pixel color
);
Is that what you wanted?

int Y, // y-coordinate of pixel
COLORREF crColor // pixel color
);

this is sort of a sub question... Is there a function for doing this in OpenGl? I tryed to use this with OpenGL but it just flickers

Two questions -
1) How do you specify the color in crColor.
2) Do you use this function in the WM_PAINT message?
