dRectangleGradient (Function) In french: dRectangleDégradé
// Draw a rectangle whose background changes from red to blue // via yellow dStartDrawing(IMG_Image1) dRectangleGradient(10, 20, 100, 150, LightRed, LightBlue, 0, LightYellow, 30)
Syntax
Drawing a rectangle by specifying the points of the rectangle and the gradient Hide the details
dRectangleGradient([<Image>, ] <X1> , <Y1> , <X2> , <Y2> , <Start color> , <End color> [, <Angle> [, <Color 3> [, <Distance color 3> [, <Color 4> [, <Distance color 4>]]]]])
<Image>: Optional control name or optional Image, WDPic or picLayer variable Versions 24 and later New in version 24
<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. <Start color>: Integer or constant Start color of gradient. This color can correspond to: <End color>: Integer or constant End color of gradient. This color can correspond to: <Angle>: Optional 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°.
<Color 3>: Optional constant or integer Color that will be used in the gradient. This color can correspond to: <Distance color 3>: Optional integer Percentage separating the start color from color 3.
<Color 4>: Optional constant or integer Color that will be used in the gradient. This color can correspond to: <Distance color 4>: Optional integer Percentage separating the start color from color 4.
Versions 21 and later New in version 21 Versions 21 and later New in version 21Remarks Gradient parameters 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. Remark: The gradient colors are not available for some systems (Windows 98 or Me for example) or for TSE 256 colors. In this case, a rectangle whose color corresponds to <Start color> is displayed. Versions 16 and later New in version 16
