GdPicture14.WPF Namespace / GdViewer Class / BurnAnnotationsToPage Method / BurnAnnotationsToPage(Boolean,Boolean) Method
Set this parameter to true, if you want to remove the initial annotation blob content from the file, otherwise set it to false.
Determines, if annotations data are rendered in vector format (means using vector graphics) on the page. Setting this parameter to false is only suitable for burning annotations into PDF documents in order to rasterize them on the page, that means to produce image-based page content.

    BurnAnnotationsToPage(Boolean,Boolean) Method
    In This Topic
    Burn, in other words flatten, the GdPicture/XMP annotations into the current page of the document displayed in the GdViewer control.

    Burning (flattening) annotations means simply including them directly into the content of the page, to which they belong, so they are not more editable. This will permanently write an annotation into the document, so it is not considered as an annotation anymore.

    This method supports annotations burning using rasterization by setting the VectorMode parameter to false. In other words, this way annotations are drawn using raster graphics on the page.

    public:
    GdPictureStatus BurnAnnotationsToPage( 
       bool RemoveInitialAnnots,
       bool VectorMode
    ) 

    Parameters

    RemoveInitialAnnots
    Set this parameter to true, if you want to remove the initial annotation blob content from the file, otherwise set it to false.
    VectorMode
    Determines, if annotations data are rendered in vector format (means using vector graphics) on the page. Setting this parameter to false is only suitable for burning annotations into PDF documents in order to rasterize them on the page, that means to produce image-based page content.

    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
    To burn your annotations using rasterization, please set the VectorMode paramater to false using this method.

    You can find out in the example for the BurnAnnotationsToPage(Boolean,Boolean) method how to burn annotations to all pages in your document.

    Example
    How to burn your custom annotations to the current page.
    'We assume that the GdViewer1 control has been properly integrated.
    If GdViewer1.DisplayFromFile("") = GdPictureStatus.OK Then
        'Annotate your document.

        If GdViewer1.BurnAnnotationsToPage(True, False) = GdPictureStatus.OK Then
            If GdViewer1.SaveDocumentToPDF("mydocument.pdf") = GdPictureStatus.OK Then
                MessageBox.Show("Done!", "GdViewer.BurnAnnotationsToPage")
            Else
                MessageBox.Show("The file can't be saved. Status: " + GdViewer1.GetStat().ToString(), "GdViewer.BurnAnnotationsToPage")
