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 ARGB() 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, Color.White);

 

    // 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, Color.Red, true);

 

    gdpictureImaging.SaveAsPNG(imageID, "output.png");

 

    // Release used resources.

    gdpictureImaging.ReleaseGdPictureImage(imageID);

}
