Return Value

A member of the GdPictureStatus enumeration.
This method automatically adjusts the vertical and horizontal image resolution in order to maintain the aspect ratio. If the intention is to change the aspect ratio, the SetVerticalResolution() and/or SetHorizontalResolution() methods should be used instead.
Resizing the image making it twice the original size.
using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("input.png");
    // Resize the image making its width twice larger. The height of the image will be changed in order to maintain the aspect ratio.
    int width = gdpictureImaging.GetWidth(imageID);
    gdpictureImaging.ResizeWidthRatio(imageID, width * 2, System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic);
    gdpictureImaging.SaveAsPNG(imageID, "output.png");
