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 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.

JPEGSubsamplingMode

A member of the JPEGSubsamplingMode enumeration. Chroma subsampling mode used for image compression in JPEG images.

Return Value

This method requires the Image Documents component to run.
