   int FillColor,
   bool AntiAlias
)

Parameters

ImageID: GdPicture image identifier.
DstLeft: Specifies the x-coordinate of the upper-left corner of the rectangle.
DstTop: Specifies the y-coordinate of the upper-left corner of the rectangle.
Width: Specifies the width of the rectangle.
Height: Specifies the height of the rectangle.
FillColor: Color of the filled rectangle. A suitable color value can be obtained by using the ARGBI() method.
AntiAlias: Set to True to apply the Antialiasing algorithm else False.

Return Value

A member of the GdPictureStatus enumeration.

Remarks

This method requires the Image Documents component to run.

Example

Filling a 150x100 pixels red rectangle with a top left corner at 200,100.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int top = 100, left = 200, width = 150, height = 100;
    int imageID = gdpictureImaging.CreateNewGdPictureImage(400, 400, System.Drawing.Imaging.PixelFormat.Format24bppRgb, gdpictureImaging.ARGBI(0, 0, 0, 0));
 
    // Fill the rectangle. The AntiAlias parameter is set to true to apply antialiasing algorithm, i.e. to improve the appearance of the rectangle boundary.
    gdpictureImaging.DrawFilledRectangle(imageID, left, top, width, height, gdpictureImaging.ARGBI(255, 255, 0, 0), true);
 
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
