Save a File from the Annotation Manager in C# .NET

To save a document created with the AnnotationManager class to a JPG image with GdPicture XMP annotation support, use the SaveDocumentToJPEG method. It can save the document to a file or a Stream object and uses the following parameters:

Either FilePath or Stream — The destination of the document you want to save, either to a file or a Stream.
Quality — The compression quality level between 0 (lowest quality and highest compression) and 100 (highest quality and lowest compression).

To include the annotations in the document’s content, use the BurnAnnotationsToPage method.

To save a JPG image from the AnnotationManager object, use the following code:

using AnnotationManager annotationManager= new AnnotationManager();
// Load a JPG image to the `AnnotationManager` object.
annotationManager.InitFromFile(@"C:\temp\source.jpg");
// Create an `AnnotationRubberStamp` object.
GdPicture14.Annotations.AnnotationRubberStamp stamp;
// Add the stamp to the `AnnotationManager` object.
stamp = annotationManager.AddRubberStampAnnot(Color.Red,
    0.5f, 0.5f, 2, 1, "APPROVED");
stamp.Rotation = 20;
// Save the annotation to the `AnnotationManager` object.
annotationManager.SaveAnnotationsToPage();
// Flatten the annotation.
annotationManager.BurnAnnotationsToPage(false);
// Save the document as a JPG image.
annotationManager.SaveDocumentToJPEG(@"C:\temp\output.jpg", 100);

Using annotationManager As AnnotationManager = New AnnotationManager()
    ' Load a JPG image to the `AnnotationManager` object.
    annotationManager.InitFromFile("C:\temp\source.jpg")
    ' Create an `AnnotationRubberStamp` object.
    Dim stamp As GdPicture14.Annotations.AnnotationRubberStamp
    ' Add the stamp to the `AnnotationManager` object.
    stamp = annotationManager.AddRubberStampAnnot(Color.Red,
        0.5F, 0.5F, 2, 1, "APPROVED")
    stamp.Rotation = 20
    ' Save the annotation to the `AnnotationManager` object.
    annotationManager.SaveAnnotationsToPage()
    ' Flatten the annotation.
    annotationManager.BurnAnnotationsToPage(False)
    ' Save the document as a JPG image.
    annotationManager.SaveDocumentToJPEG("C:\temp\output.jpg", 100)
End Using

To save a document created with the AnnotationManager class to a PDF file with GdPicture XMP annotation support, use the SaveDocumentToPDF method. It can save the document to a file or a Stream object and uses the file path as a string or a Stream object as its parameter.

To include the annotations in the document’s content, use the BurnAnnotationsToPage method.

To save a PDF file from the AnnotationManager object, use the following code:

using AnnotationManager annotationManager= new AnnotationManager();
// Load a PDF file to the `AnnotationManager` object.
annotationManager.InitFromFile(@"C:\temp\source.pdf");
// Select the first page.
annotationManager.SelectPage(1);
// Create an `AnnotationRubberStamp` object.
GdPicture14.Annotations.AnnotationRubberStamp stamp;
// Add the stamp to the `AnnotationManager` object.
stamp = annotationManager.AddRubberStampAnnot(Color.Red,
    0.5f, 0.5f, 2, 1, "APPROVED");
stamp.Rotation = 20;
// Save the annotation to the `AnnotationManager` object.
annotationManager.SaveAnnotationsToPage();
// Flatten the annotation.
annotationManager.BurnAnnotationsToPage(false);
// Save the document as a PDF file.
annotationManager.SaveDocumentToPDF(@"C:\temp\output.pdf", 100);

Using annotationManager As AnnotationManager = New AnnotationManager()
    ' Load a PDF file to the `AnnotationManager` object.
    annotationManager.InitFromFile("C:\temp\source.pdf")
    ' Select the first page.
    annotationManager.SelectPage(1)
    ' Create an `AnnotationRubberStamp` object.
    Dim stamp As GdPicture14.Annotations.AnnotationRubberStamp
    ' Add the stamp to the `AnnotationManager` object.
    stamp = annotationManager.AddRubberStampAnnot(Color.Red,
        0.5F, 0.5F, 2, 1, "APPROVED")
    stamp.Rotation = 20
    ' Save the annotation to the `AnnotationManager` object.
    annotationManager.SaveAnnotationsToPage()
    ' Flatten the annotation.
    annotationManager.BurnAnnotationsToPage(False)
    ' Save the document as a PDF file.
    annotationManager.SaveDocumentToPDF("C:\temp\output.pdf", 100)
End Using

To save a document created with the AnnotationManager class to a TIFF image with GdPicture XMP annotation support, use the SaveDocumentToTIFF method. It can save the document to a file or a Stream object and uses the following parameters:

Either FilePath or Stream — The destination of the document you want to save, either to a file or a Stream.
Compression — A member of the TiffCompression enumeration. It specifies the compression method.

To include the annotations in the document’s content, use the BurnAnnotationsToPage method.

To save a TIFF image from the AnnotationManager object, use the following code:

using AnnotationManager annotationManager= new AnnotationManager();
// Load a TIFF image to the `AnnotationManager` object.
annotationManager.InitFromFile(@"C:\temp\source.tiff");
// Select the first page.
annotationManager.SelectPage(1);
// Create an `AnnotationRubberStamp` object.
GdPicture14.Annotations.AnnotationRubberStamp stamp;
// Add the stamp to the `AnnotationManager` object.
stamp = annotationManager.AddRubberStampAnnot(Color.Red,
    0.5f, 0.5f, 2, 1, "APPROVED");
stamp.Rotation = 20;
// Save the annotation to the `AnnotationManager` object.
annotationManager.SaveAnnotationsToPage();
// Flatten the annotation.
annotationManager.BurnAnnotationsToPage(false);
// Save the document as a TIFF image.
annotationManager.SaveDocumentToTIFF(@"C:\temp\output.tiff", 100);

Using annotationManager As AnnotationManager = New AnnotationManager()
    ' Load a TIFF image to the `AnnotationManager` object.
    annotationManager.InitFromFile("C:\temp\source.tiff")
    ' Select the first page.
    annotationManager.SelectPage(1)
    ' Create an `AnnotationRubberStamp` object.
    Dim stamp As GdPicture14.Annotations.AnnotationRubberStamp
    ' Add the stamp to the `AnnotationManager` object.
    stamp = annotationManager.AddRubberStampAnnot(Color.Red,
        0.5F, 0.5F, 2, 1, "APPROVED")
    stamp.Rotation = 20
    ' Save the annotation to the `AnnotationManager` object.
    annotationManager.SaveAnnotationsToPage()
    ' Flatten the annotation.
    annotationManager.BurnAnnotationsToPage(False)
    ' Save the document as a TIFF image.
    annotationManager.SaveDocumentToTIFF("C:\temp\output.tiff", 100)
End Using

GdPicture.NET SDK allows you to save GdPicture XMP annotations located in a file with the SaveAnnotationsToXMP and SaveAnnotationsToXMPEx methods. They allow you to do the following:

Save annotations from an image.
Save annotations from a specific page of a multipage file.
Save annotations from all pages of a multipage file.

Saving Annotations from an Image

To save GdPicture XMP annotations created with the AnnotationManager class from an image to an XML file or a Stream object, use the SaveAnnotationsToXMP method. It uses the file path as a string or a Stream object as its parameter.

To save annotations from an image, use the following code:

using AnnotationManager annotationManager= new AnnotationManager();
// Load an image to the `AnnotationManager` object.
annotationManager.InitFromFile(@"C:\temp\source.jpg");
// Create an `AnnotationRubberStamp` object.
GdPicture14.Annotations.AnnotationRubberStamp stamp;
// Add the stamp to the `AnnotationManager` object.
stamp = annotationManager.AddRubberStampAnnot(Color.Red,
    0.5f, 0.5f, 2, 1, "APPROVED");
stamp.Rotation = 20;
// Save the annotation to the `AnnotationManager` object.
annotationManager.SaveAnnotationsToPage();
// Save the annotation to an XML file.
annotationManager.SaveAnnotationsToXMP(@"C:\temp\output.xml");

Using annotationManager As AnnotationManager = New AnnotationManager()
    ' Load an image to the `AnnotationManager` object.
    annotationManager.InitFromFile("C:\temp\source.jpg")
    ' Create an `AnnotationRubberStamp` object.
    Dim stamp As GdPicture14.Annotations.AnnotationRubberStamp
    ' Add the stamp to the `AnnotationManager` object.
    stamp = annotationManager.AddRubberStampAnnot(Color.Red,
        0.5F, 0.5F, 2, 1, "APPROVED")
    stamp.Rotation = 20
    ' Save the annotation to the `AnnotationManager` object.
    annotationManager.SaveAnnotationsToPage()
    ' Save the annotation to an XML file.
    annotationManager.SaveAnnotationsToXMP("C:\temp\output.xml")
End Using

Saving Annotations from a Specific Page

To save the GdPicture XMP annotations created with the AnnotationManager class from a specific document page to an XML file or a Stream object, use the SaveAnnotationsToXMP method. It uses the file path as a string, or a Stream object as its parameter.

Use the SelectPage method for multipage files like PDF documents and TIFF images.

To save annotations on the first page of a PDF document, use the following code:

using AnnotationManager annotationManager= new AnnotationManager();
// Load a PDF document to the `AnnotationManager` object.
annotationManager.InitFromFile(@"C:\temp\source.pdf");
// Select the first page.
annotationManager.SelectPage(1);
// Create an `AnnotationRubberStamp` object.
GdPicture14.Annotations.AnnotationRubberStamp stamp;
// Add the stamp to the `AnnotationManager` object.
stamp = annotationManager.AddRubberStampAnnot(Color.Red,
    0.5f, 0.5f, 2, 1, "APPROVED");
stamp.Rotation = 20;
// Save the annotation to the `AnnotationManager` object.
annotationManager.SaveAnnotationsToPage();
// Save the annotation to an XML file.
annotationManager.SaveAnnotationsToXMP(@"C:\temp\output.xml");

Using annotationManager As AnnotationManager = New AnnotationManager()
    ' Load a PDF document to the `AnnotationManager` object.
    annotationManager.InitFromFile("C:\temp\source.pdf")
    ' Select the first page.
    annotationManager.SelectPage(1)
    ' Create an `AnnotationRubberStamp` object.
    Dim stamp As GdPicture14.Annotations.AnnotationRubberStamp
    ' Add the stamp to the `AnnotationManager` object.
    stamp = annotationManager.AddRubberStampAnnot(Color.Red,
        0.5F, 0.5F, 2, 1, "APPROVED")
    stamp.Rotation = 20
    ' Save the annotation to the `AnnotationManager` object.
    annotationManager.SaveAnnotationsToPage()
    ' Save the annotation to an XML file.
    annotationManager.SaveAnnotationsToXMP("C:\temp\output.xml")
End Using

Saving Annotations from All Pages

To save the GdPicture XMP annotations created with the AnnotationManager class from all pages of a multipage file to an XML file or a Stream object, use the SaveAnnotationsToXMPEx method. It uses the file path as a string or a Stream object as its parameter.

To save annotations from all pages of a PDF document, use the following code:

using AnnotationManager annotationManager= new AnnotationManager();
// Load a PDF document to the `AnnotationManager` object.
annotationManager.InitFromFile(@"C:\temp\source.pdf");
// Create an `AnnotationRubberStamp` object.
GdPicture14.Annotations.AnnotationRubberStamp stamp;
// Add the stamp to the `AnnotationManager` object.
stamp = annotationManager.AddRubberStampAnnot(Color.Red,
    0.5f, 0.5f, 2, 1, "APPROVED");
stamp.Rotation = 20;
// Save the annotation to the `AnnotationManager` object.
annotationManager.SaveAnnotationsToPage();
// Save the annotation to an XML file.
annotationManager.SaveAnnotationsToXMPEx(@"C:\temp\output.xml");

Using annotationManager As AnnotationManager = New AnnotationManager()
    ' Load a PDF document to the `AnnotationManager` object.
    annotationManager.InitFromFile("C:\temp\source.pdf")
    ' Create an `AnnotationRubberStamp` object.
    Dim stamp As GdPicture14.Annotations.AnnotationRubberStamp
    ' Add the stamp to the `AnnotationManager` object.
    stamp = annotationManager.AddRubberStampAnnot(Color.Red,
        0.5F, 0.5F, 2, 1, "APPROVED")
    stamp.Rotation = 20
    ' Save the annotation to the `AnnotationManager` object.
    annotationManager.SaveAnnotationsToPage()
    ' Save the annotation to an XML file.
    annotationManager.SaveAnnotationsToXMPEx("C:\temp\output.xml")
End Using
