<Image control>.DrawRectangle(<X1> , <Y1> , <X2> , <Y2> [, <Background> [, <Line>]])
<Image control>: Control name
Name of the Image control to use.
<X1>: Integer
X coordinate (in pixels) of top left corner of rectangle.
<Y1>: Integer
Y coordinate (in pixels) of top left corner of rectangle.
<X2>: Integer
X coordinate (in pixels) of bottom right corner of rectangle.
<Y2>: Integer
Y coordinate (in pixels) of bottom right corner of rectangle.
<Background>: Integer, constant or Background variable (optional)
  • Background color of rectangle. This color can be:
  • Characteristics of background:
    • Versions 21 and later
