<WDPic variable>.DrawRectangleGradient (Function) In french: <Variable WDPic>.DessineRectangleDégradé Draws a rectangle in a variable of type WDPic (on the background layer).
MyWDPicImage is WDPic = "Test.gif" // Draw a rectangle whose background changes from red to blue // via yellow MyWDPicImage.DrawRectangleGradient(10, 20, 100, 150, LightRed, LightBlue, 0, LightYellow, 30) IMG_MyDrawing = MyWDPicImage
Syntax
Drawing a rectangle by specifying the points of the rectangle and the gradient Hide the details
<WDPic image>.DrawRectangleGradient(<X1> , <Y1> , <X2> , <Y2> , <Start color> , <End color> [, <Angle> [, <Color 3> [, <Distance color 3> [, <Color 4> [, <Distance color 4>]]]]])
<WDPic image>: WDPic variable Name of the WDPic variable to be used. Only the background layer will be handled. <X1>: Integer X-coordinate (in pixels) of the upper-left corner of the rectangle. <Y1>: Integer Y-coordinate (in pixels) of the upper-left corner of the rectangle. <X2>: Integer X-coordinate (in pixels) of the lower-right corner of the rectangle. <Y2>: Integer Y-coordinate (in pixels) of the lower-right corner of the rectangle. <Start color>: Integer or constant Start color of the gradient. This color can correspond to: <End color>: Integer or constant End color of the 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.
Remarks 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.
