Parameters

ImageID
GdPicture image identifier.
Angle
Angle of rotation in degrees.
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.
PenWidth
Width, in pixel, of the pen used to draw the rectangle.
PenColor

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
Drawing a rotated rectangle on a GdPicture image.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int left = 50, top = 100, width = 250, height = 150;
    float angle = 30.0f;
    int penWidth = 20;
    Color penColor = gdpictureImaging.ARGBI(255, 0, 0, 255);
    int imageID = gdpictureImaging.CreateNewGdPictureImage(400, 400, System.Drawing.Imaging.PixelFormat.Format24bppRgb, gdpictureImaging.ARGBI(0, 0, 0, 0));
 
    // Draw the rotated rectangle. The AntiAlias parameter is set to true to apply antialiasing algorithm, i.e. to improve the appearance of the rectangle boundary.
    gdpictureImaging.DrawRotatedRectangle(imageID, angle, left, top, width, height, penWidth, penColor, true);
 
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
 
    // Release used resources.
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
