I'm experimenting with GetPixel functions (in order to find the fastest) and have this simple part in my script: Local $iWidth = 150 Local $iHeight = 300 Local $array[$iHeight][$iWidth] For $i = 1 To $iHeight Step 1     For $j = 1 To $iWidth Step 1         $array[$i-1][$j-1] = PixelGetColor($iHeight-1, $iWidth-1, $Handle)     Next Next Trying to get the equivalent using the GDI+ library (more specifically, using the _GDIPlus_BitmapLockBits function) I've got this code: Global $Handle = WinG
