| Does anyone know what the contstituent RGB (a?) parts are for GDI32's ReadPixel() function? When I use them with WritePixelFast in Blitz3D, the colours come out wring. I can only assume this is because ioif an omitted alpha value, or perhaps the RGB isn't in that order for most/least significant..? |

| That explains it! Thanks, Yasha. I think I'd reversed the entire order putting Alpha on the end (Least) in attempt to convert it. |
