Example
MyWDPic is WDPic = "Test.gif"
 
// Declare the background color of different drawings
// made in MyWDPic
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 use. 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 preset color of WLanguage.
  • Versions 23 and later
    a Color variable. In this case, the opacity specified in the variable is taken into account.
    New in version 23
    a Color variable. In this case, the opacity specified in the variable is taken into account.
    a Color variable. In this case, the opacity specified in the variable is taken into account.
    an Color variable. 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
Default type of hatching for the background of 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).
  • Versions 23 and later
    If the <Color> parameter corresponds to a Color variable, this parameter must not be specified: the opacity specified in the variable will be taken into account.
    New in version 23
    If the <Color> parameter corresponds to a Color variable, this parameter must not be specified: the opacity specified in the variable will be taken into account.
    If the <Color> parameter corresponds to a Color variable, this parameter must not be specified: the opacity specified in the variable will be taken into account.
