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);

}
