FillPie
Graphics.FillPie method (1 of 4)
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");
}
