)

public:
GdPictureStatus SaveAsJPEG( 
   int ImageID,
   String^ FilePath,
   int Quality,
   bool Progressive
)

Parameters

ImageID: A unique image identifier of the GdPicture image representing the image to be saved.
FilePath: The file path where the specified image will be saved. Use the empty string to allow the control to prompt users to select a file. If the specified file already exists, it will be overwritten.
You can subsequently use the GdPictureImaging.GetLastPath method to retrieve the path of the selected file.
Quality: The compression quality level from 0 to 100. 0 means the worst quality and the best compression, 100 means the best quality and the worst compression. The default value is 75.
Progressive: Set this parameter to true to save the image as a progressive JPEG, otherwise set it to false. The default value is false.

Return Value

A member of the GdPictureStatus enumeration. If the method has been successfully followed, then the return value is GdPictureStatus.OK. We strongly recommend always checking this status first.

Example

Performing a negative effect on a jpeg image.

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);
    gdpictureImaging.FxNegative(imageID);
    gdpictureImaging.SaveAsJPEG(imageID, "image.jpg", 75, true);
    gdpictureImaging.ReleaseGdPictureImage(imageID);
}
