Example

Rotating a jpeg image by 75° using a light blue background color.

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    // LoadInMemory parameter is set to true in order to be able to update the input file.
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image.jpg", true);
 
    // Rotate the image by 75° with a light blue background color.
    gdpictureImaging.RotateAngleBackColor(imageID, 75, Color.LightBlue);
    gdpictureImaging.SaveAsJPEG(imageID, "image.jpg", 75);
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
