SaveToFile(String,Boolean) Method

In This Topic

Packs and saves the currently loaded PDF document to a file according to a file path you have specified.

Please note that you can highly reduce the file size of the PDF document by enabling the use of the standard compression mechanism during saving.

public function SaveToFile( 
   FilePath : String,
   PackDocument : boolean
) : GdPictureStatus;

public: GdPictureStatus SaveToFile( 
   string* FilePath,
   bool PackDocument
)

public:
GdPictureStatus SaveToFile( 
   String^ FilePath,
   bool PackDocument
)

Parameters

FilePath

The file path where the currently loaded PDF document will be saved. If the specified file already exists, it will be overwritten.

You are allowed to overwrite the currently opened PDF document only if the document has been loaded into memory setting the LoadInMemory parameter to true in the previously called LoadFromFile method.

PackDocument

Specifies if the toolkit has to pack the current document before the save process to reduce its size.

Set this parameter to true if you want to pack the PDF document before saving. Please note that the whole saving process can be as a result slower with some documents.

If you set this parameter to false, the PDF document will remain unpacked after the save process.

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.

Remarks

The pack mode is an option allowing the toolkit the removal of any unused PDF objects and to better compress some other objects before saving the PDF document. Using this option leads to recreation of a brand new PDF document by cloning all existing pages of the current document onto a brand new document.

You can also combine this parameter with the standard compression mechanism as well as you can benefit from using the RemoveUnusedResources method to eliminate all unused resources from your saved PDF document.

This method requires the PDF Processing component to run.

Example

How to save the PDF document with enabled pack mode.

VB.NET
C#

Dim caption As String = "Example: SaveToFile"
Dim gdpicturePDF As New GdPicturePDF()
If gdpicturePDF.LoadFromFile("Input.pdf", False) = GdPictureStatus.OK Then
    'The file will save without being compressed.
    gdpicturePDF.EnableCompression(False)
    If gdpicturePDF.GetStat() <> GdPictureStatus.OK Then
        GoTo [error]
    End If
    If gdpicturePDF.SaveToFile("uncompressed.pdf", False) = GdPictureStatus.OK Then
        MessageBox.Show("Saving file without compression and without packing has been successful.", caption)
    End If
    If gdpicturePDF.SaveToFile("uncompressed_pack.pdf", True) = GdPictureStatus.OK Then
        MessageBox.Show("Saving file without compression and with packing has been successful.", caption)
    End If
            
    'The file will save using the compression mechanism.
    gdpicturePDF.EnableCompression(True)
    If gdpicturePDF.GetStat() <> GdPictureStatus.OK Then
