LinearGradient()

Syntax

LinearGradient(x1, y1, x2, y2)
Description
Sets the drawing gradient to have a linear shape defined by the two points x1,y1 and x2,y2.

Parameters

x1, y1 The position at which to apply the current background color.
x2, y2 The position at which to apply the current front color.

Return value

None.

Remarks

Additional colors can be added to the gradient with the GradientColor() command.

Note: This command only has an effect with ImageOutput() and CanvasOutput(). The gradient only affects the drawing commands when #PB_2DDrawing_Gradient is set with the DrawingMode() command.

Example

  If OpenWindow(0, 0, 0, 400, 200, "2DDrawing Example", #PB_Window_SystemMenu | #PB_Window_ScreenCentered)
    If CreateImage(0, 400, 200) And StartDrawing(ImageOutput(0))
      Box(0, 0, 400, 200, $FFFFFF)
      
      DrawingMode(#PB_2DDrawing_Gradient)      
      BackColor($00FFFF)
      FrontColor($FF0000)
      
      LinearGradient(0, 0, 200, 200)    
      Circle(100, 100, 100)   
      LinearGradient(350, 100, 250, 100)
      Circle(300, 100, 100)
      
      StopDrawing() 
      ImageGadget(0, 0, 0, 400, 200, ImageID(0))
    EndIf
    
    Repeat
      Event = WaitWindowEvent()
    Until Event = #PB_Event_CloseWindow
  EndIf
