Delphi获取BMP图片指定点RGB值.rar

delphi获取图片指定点RGB颜色值,载入一张BMP图像,鼠标单击图像任意处,将获取该处的RGB颜色分量图。任何一种颜色都是由RGB分量值构成,获取这些分量值,就可以改变这些值,从而改变颜色,为程序的进一步处理提供基础保障,获取RGB颜色分量,相关代码如下: procedure TForm1.SpeedButton1Click(Sender: TObject); begin if OpenPictureDialog1.Execute then begin image1.Picture.LoadFromFile(OpenPicturedialog1.FileName); Form1.Canvas.Draw(0,0,image1.Picture.Bitmap); end; end;
