Graphics.FillPie

FillPie(Brush, Rectangle, float, float)

Fills the interior of a pie section defined by an ellipse specified by a RectangleF structure and two radial lines.

public void FillPie(Brush brush, Rectangle rect, float startAngle, float sweepAngle)

Parameter	Type	Description
brush	Brush	Brush that determines the characteristics of the fill.
rect	Rectangle	Rectangle structure that represents the bounding rectangle that defines the ellipse from which the pie section comes.
startAngle	Single	Angle in degrees measured clockwise from the x-axis to the first side of the pie section.
sweepAngle	Single	Angle in degrees measured clockwise from the startAngle parameter to the second side of the pie section.

Exceptions

exception	condition
ArgumentNullException	brush is null.

Examples

The following example shows how to compose an animated GIF image from individual GIF blocks.

[C#]

string dir = "c:\\temp\\";

// Create a GIF image 100 x 100 px.
// The first block is fully black by default.
using (Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock firstBlock = new Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock(100, 100))
using (Aspose.Imaging.FileFormats.Gif.GifImage gifImage = new Aspose.Imaging.FileFormats.Gif.GifImage(firstBlock))
{
    // The first circle is red
    Aspose.Imaging.Brushes.SolidBrush brush1 = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Red);

    // The second circle is black
    Aspose.Imaging.Brushes.SolidBrush brush2 = new Aspose.Imaging.Brushes.SolidBrush(Aspose.Imaging.Color.Black);

    // Gradually inscrease the angle of the red arc shape.
    for (int angle = 10; angle <= 360; angle += 10)
    {
        Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock block = new Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock(100, 100);

        Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(block);
        gr.FillPie(brush1, block.Bounds, 0, angle);

        gifImage.AddBlock(block);
    }

    // Gradually inscrease the angle of the black arc and wipe out the red arc.
    for (int angle = 10; angle <= 360; angle += 10)
    {
        Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock block = new Aspose.Imaging.FileFormats.Gif.Blocks.GifFrameBlock(100, 100);

        Aspose.Imaging.Graphics gr = new Aspose.Imaging.Graphics(block);
        gr.FillPie(brush2, block.Bounds, 0, angle);
        gr.FillPie(brush1, block.Bounds, angle, 360 - angle);

        gifImage.AddBlock(block);
    }

    gifImage.Save(dir + "animated_radar.gif");
}
