Declares the default background color for the rectangles, circles, etc., used in a variable of type WDPic.
Example
MyWDPic is WDPic = "Test.gif"

// Declare the background color of the different drawings in the MyWDPic variable
MyWDPic.Background(LightGreen)

IMG_MyDrawing = MyWDPic
Syntax
<WDPic image>.Background(<Color> [, <Fill style> [, <Type of hatching> [, <Opacity>]]])
<WDPic image>: WDPic variable
Name of the WDPic variable to be used. Only the background layer will be handled.
<Color>: Integer or constant
Default background color of different drawings. This color can correspond to:
  • an RGB color (returned by RGB),
  • an HSL color (returned by HSL),
  • a WLanguage preset color.
  • a variable of type Color. In this case, the opacity specified in the variable is taken into account.
<Fill style>: Optional integer or Integer constant
Default background fill of different drawings:
BackgroundHatchedBackground filled with hatching.
Corresponds to value 2 for compatibility.
BackgroundSolid
(Default value)
Solid background.
Corresponds to value 0 for compatibility.
BackgroundTransparentTransparent background (<Color> is ignored).
Corresponds to value 1 for compatibility.

<Type of hatching>: Optional integer
Type of background hatching used by default in the different drawings. To use this parameter, the value of <Fill style> must be equal to 2. If the value of <Fill style> is different from 2, <Type of hatching> is ignored. The different types of hatching are:
  • 0: Horizontal hatching
  • 1: Vertical hatching
  • 2: Diagonal hatching at 60%
  • 3: Diagonal hatching at 120%
  • 4 (by default): Criss-crossed hatching
  • 5: Diagonal crossed hatching
<Opacity>: Optional integer
Opacity of color, included between 0 (transparent) and 255 (opaque). An opacity set to 128 is used to blend 50% of the color with the existing color found in the control.
Remarks:
  • This opacity will be taken into account if the drawing was initialized with the dWithOpacity constant (<WDPic variable>.StartDrawing).
  • If the <Color> parameter corresponds to a variable of type Color, this parameter must not be specified: the opacity specified in the variable will be taken into account.
