Hi, I am having trouble understanding the readpixelfast command, i have drawn something, locked the buffer run this pixelcolour% = ReadPixelFast (220, 100) then unlocked the buffer and printed the pixelcolour% and i get some wierd results. for example pure white is -1. am i using this command right and if so is there anyway to convert it to a proper useable rgb value? |

red% = PixelColor% Shr 16 And 255 And Shl 0 green% = PixelColor% Shr 8 And 255 And Shl 0 blue% = PixelColor% Shr 0 And 255 And Shl 0+BlackD |

thanks, it works fine but I didn't use the code "and shl 0" on the end of any. |
