Hi Chris,

You can access the RGB property of a TDibGraphic to change the color of any individual

picture and perform modifications. For example, to access every pixel in a TImageScrollBox:

X, Y : Integer;
Graphic : TDibGraphic;
Graphic := ImageScrollBox.Graphic;

for Y := 0 to (DibGraphic.Height-1) do
for X := 0 to (DibGraphic.Width-1) do
Graphic.Rgb[X,Y].Red := ??
Graphic.Rgb[X,Y].Green := ??
Graphic.Rgb[X,Y].Blue := ??

Best regards,
