PathGradientBrush::SetCenterColor method

The PathGradientBrush::SetCenterColor method sets the center color of this path gradient brush. The center color is the color that appears at the brush's center point.

Syntax

Status SetCenterColor(
  IN const Color & color
);

Parameters

color

Type: const Color

Reference to a Color object that specifies the center color.

Return Value

Type: Type: Status

If the method succeeds, it returns Ok, which is an element of the Status enumeration.

If the method fails, it returns one of the other elements of the Status enumeration.

Remarks

By default the center point is the centroid of the brush's boundary path, but you can set the center point to any location inside or outside the path.

Examples

The following example creates a PathGradientBrushobject based on an ellipse. The code calls the PathGradientBrush::SetCenterColor method of the PathGradientBrushobject to set the center color to blue. The PathGradientBrush::SetSurroundColors method sets the color along the entire boundary to aqua. The FillRectangle Methods method uses the path gradient brush to paint a rectangle that contains the ellipse.

VOID Example_SetCenter(HDC hdc)
{
   Graphics graphics(hdc);

   // Create a path that consists of a single ellipse.
   GraphicsPath path;
   path.AddEllipse(0, 0, 200, 100);

   // Use the path to construct a brush.
   PathGradientBrush pthGrBrush(&path);

   // Set the color at the center of the path to blue.
   pthGrBrush.SetCenterColor(Color(255, 0, 0, 255));

   // Set the color along the entire boundary of the path to aqua.
   Color colors[] = {Color(255, 0, 255, 255)};
   INT count = 1;
   pthGrBrush.SetSurroundColors(colors, &count);

   graphics.FillRectangle(&pthGrBrush, 0, 0, 300, 300); 
}
