quick SetPixel() example?

[Alan]

I've looked everywhere but cannot seem to find a good example usage of SetPixel()... could someone please post an example of this function using valid parameters?

When I try to use it with the following code

#include <windows.h>
int main() {
   SetPixel(NULL, 0, 0, RGB(255, 255, 255));
}

I get an error:

[Linker error] undefined reference to `SetPixel@16'
ld returned 1 exit status

It works fine on MSVC++, what compiler are you using? [or maybe your windows.h file is corrupt]

[Bazzy]

Are you linking to the right libraries?

[Alan]

Im using Dev-C++. Its possible that my windows.h is corrupt. ive had several linking problems like this.

I noticed that I do not have Gdi32.lib in my lib/ directory. Do I need this?

[helios]

You need to add -lgdi32 to the linker flags.

[Alan]

that worked! no errors. thanks!

It's worth noting that:

1) SetPixelV is faster than SetPixel

2) SetPixelV is still dreadfully slow.

For faster per-pixel drawing, look up SetDIBits or CreateDIBSection
