Convert color value into gray-scaled color value (Views: 27)
Problem/Question/Abstract: How can I convert the color value into gray-scaled value? Answer: If you want to convert a colored image into same gray scaled, then you must convert the color of the each pixel by the next schema: function RgbToGray(Source: TColor): TColor; var Target: Byte; begin Target := Round((0.30 * GetRValue(Source)) + (0.59 * GetGValue(Source)) + (0.11 * GetBValue(Source))); Result := RGB(Target, Target, Target); end; |
