Parameters

ImageID: GdPicture image identifier.
NewImageWidth: New image width in pixel.
NewImageHeight: New image height in pixel.
InterpolationMode: A member of the Drawing2D.InterPolationMode enumeration.

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.

This method requires the Image Documents component to run.

Resizing a 1920x1080 pixels image to a 1080x720 pixels image.

C#

using (GdPictureImaging gdpictureImaging = new GdPictureImaging())
{
    int imageID = gdpictureImaging.CreateGdPictureImageFromFile("image_1920x1080.jpg", false);
 
    // Set the new dimensions for your image.
    int newImageWidth = 1080;
    int newImageHeight = 720;
 
    // Resize the image.
    gdpictureImaging.Resize(imageID, newImageWidth, newImageHeight, System.Drawing.Drawing2D.InterpolationMode.Default);
    gdpictureImaging.SaveAsJPEG(imageID, "image_1080x720.jpg");
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
