If you are using ImageLib, then you could draw on the back layer with transparency.
That way, many drawings can overlap without hiding each other.
Code:
Sub App_Start
Form1.Show
drawer1.New1("Form1",false)
bmpSrc.New1(AppPath & "\smiley.gif") 'Loads an image from a file named smiley.gif
rectSrc.New1(0,0,bmpSrc.Width,bmpSrc.Height) 'Same size as the image.
rectDest.New1(100,100,25,25)
drawer1.SetTransparentColor1(bmpSrc.GetPixel1(0,0)) 'Sets the transparent color to be the color of pixel (0,0) in the bitmap
drawer1.DrawImage1(bmpSrc.Value,rectSrc.Value,rectDest.Value,true)
rectDest.X = 80
drawer1.DrawImage1(bmpSrc.Value,rectSrc.Value,rectDest.Value,true)
drawer1.Refresh2(rectDest.Value)
End Sub
