Can your video handle 16, 256, 32768, 16777216, or more colors (Views: 708)
Problem/Question/Abstract: Can your video handle 16, 256, 32768, 16777216, or more colors? Answer: You can use WIN API function GetDeviceCaps() to calculate the number of colors supported by the current video mode. To make it even easier to use, here's a function that will simply return the number of maximum simultaneous colors current video device can handle: function GetColorsCount: integer; var h: hDC; begin Result := 0; try h := GetDC(0); Result := 1 shl ( GetDeviceCaps(h, PLANES) * GetDeviceCaps(h, BITSPIXEL) ); finally ReleaseDC(0, h); end; end; |
