@loulou2522: Do you mean like this? Thanks to jacdelad as well.

Code: Select all

CreateImage(1,100,100,24,#White) ; White square created, but you can load one.

CopyImage(1,2) ; Copy it.

; Draw a red line down the copy.
StartDrawing(ImageOutput(2))
Line(50,0,1,100,#Red)
StopDrawing()

SaveImage(2,GetTemporaryDirectory()+"image-test.bmp") ; Save copied image with line.

; Do whatever next, because the original image is still just a white square.
