Finding the color of a pixel
Hey All,
I know that there has to be a way to determine the color of a pixel in 256 color mode, I'm just not sure what is is :-).
Can anyone help?
Thanks.
Ok,
here's some source code :
here's some source code :
code:UCHAR* buffer;DDSURFACEDESC2 ddsd;UCHAR TheEntry;PALETTEENTRY entry;int r, g, b;ZeroMemory(&ddsd, sizeof(ddsd));ddsd.dwSize = sizeof(ddsd);lpDDSWhatever->Lock(NULL, &ddsd, DDLOCK_SURFACEMEMORYPTR | DDLOCK_WAIT, NULL);buffer = (UCHAR*)ddsd.lpSurface;TheEntry = buffer[x+(y*ddsd.lPitch)];lpDDSWhatever->Unlock(NULL);lpDDSWhatever->GetEntries(0, 0, 1, &entry[TheEntry]);r = entry.peRed;g = entry.peGreen;b = entry.peBlue;
This should work, I hope.
