When the EnableOverrideLineColor property is set to True, this property is used to define a color to use as a picture's line, instead of its original color. In scripts, use VBScript's RGB method to create a color to link to this property. Default value of this property is red (RGB(255, 0, 0)). Example:

Sub DrawPicture1_Click()
  OverrideLineColor = RGB(0, 0, 255)
End Sub
