Background (Type of variable)

In french: Fond

The Background type defines the advanced characteristics of the element background. The characteristics of this background can be defined and changed using different WLanguage properties.

Remark: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.

Example

// Draw a rectangle with blue borders, green background and rounded corners
// in an Image control

// Initializes the drawing in the Image control
dStartDrawing(IMG_Drawing)

Rect is Rectangle
Rect.X = 10
Rect.Y = 15
Rect.Width = 100
Rect.Height = 150
BorderStyle is Border
BorderStyle.Color = LightBlue
BorderStyle.Round = 30
BorderStyle.Thickness = 1
BackgroundStyle is Background
BackgroundStyle.Color = LightGreen
dBorder(Rect, BorderStyle, BackgroundStyle)

Remarks

Properties specific to Background variables

The following properties can be used to handle the background of an element:

Property name	Type used	Effect

Color	Color variable	Background color.
Gradient		Gradient of the background color: ColorStart property (Color type): Start color of the gradient. ColorEnd property (Color type): End color of the gradient. Angle property (integer): Angle that will be used for the selection of colors in the gradient. The angle value is included between 0 (horizontal angle, default value) and 360°. Color3 property (Color type): Color that will be used in the gradient. DistanceColor3 property (integer): Percentage separating the start color from color 3. Color4 property (Color type): Color that will be used in the gradient. DistanceColor4 property (integer): Percentage separating the start color from color 4. The color parameters are used as follows: The angle is used to define the orientation of the gradient. Gradients with 3 or 4 colors are only available for 0 or 90 degree angles. Remarks: On some systems (e.g., 256-color Remote Desktop Connection), gradients are not available. In this case, the color defined via the ColorStart property is used. Gradient backgrounds are not supported in docx documents.
Hatch	Integer constant	Type of hatching used: HatchNone: No hatching. HatchCrossed: Criss-crossed hatching. HatchCrossedDiagonal: Diagonal crossed hatching. HatchDiagonal: Diagonal hatching at 60%. HatchDiagonalBottom: Diagonal hatching at 120%. HatchHorizontal: Horizontal hatching. HatchVertical: Vertical hatching.
Type	Integer constant	Type of background: BackgroundSolid: Solid background. BackgroundTransparent: Transparent background (the Color property is ignored). BackgroundHatched: Hatched background (the Hatch property is taken into account). BackgroundGradient: Background with color gradient (the Gradient property is taken into account).

Functions that use Background variables


dBorder	Draws the borders.
dRectangle	Draws a rectangle: in an Image control, in an Image variable, in a WDPic variable (on the background layer), in a picLayer variable.
dRectangleGradient	Draws a rectangle: in an Image control, in an Image variable, in a WDPic variable (on the background layer), in a picLayer variable.
dRoundedRectangle	Draws a rounded rectangle: in an Image control, in an Image variable, in a WDPic variable (on the background layer), in a picLayer variable.

The syntaxes of dRectangle, dRoundedRectangle and dRectangleGradient that use Border or Background variables are not available in Android. You must use dBorder.
