VB.NET


''' <summary>
''' Renders PDF page with the PDF annotations.
''' </summary>
''' <param name="page">The page of PDF document.</param>
Public Shared Function RenderPdfPageWithPdfAnnotations(page As Vintasoft.Imaging.Pdf.Tree.PdfPage) As Vintasoft.Imaging.VintasoftImage
    ' get rendering settings of PDF page
    Dim renderingSettings As Vintasoft.Imaging.Codecs.Decoders.PdfRenderingSettings = page.Document.RenderingSettings
    ' save previous value of PdfRenderingSettings.DrawPdfAnnotations property
    Dim prevDrawPdfAnnotations As Boolean = renderingSettings.DrawPdfAnnotations
    ' enable rendering of PDF annotations on PDF page
    renderingSettings.DrawPdfAnnotations = True

    ' render PDF page
    Dim image As Vintasoft.Imaging.VintasoftImage = page.Render()

    ' restore value of PdfRenderingSettings.DrawPdfAnnotations property
    renderingSettings.DrawPdfAnnotations = prevDrawPdfAnnotations

    ' return the image of PDF page
    Return image
End Function


/// <summary>
/// Renders PDF page with the PDF annotations.
/// </summary>
/// <param name="page">The page of PDF document.</param>
public static Vintasoft.Imaging.VintasoftImage RenderPdfPageWithPdfAnnotations(
    Vintasoft.Imaging.Pdf.Tree.PdfPage page)
{
    // get rendering settings of PDF page
    Vintasoft.Imaging.Codecs.Decoders.PdfRenderingSettings renderingSettings = page.Document.RenderingSettings;
    // save previous value of PdfRenderingSettings.DrawPdfAnnotations property
    bool prevDrawPdfAnnotations = renderingSettings.DrawPdfAnnotations;
    // enable rendering of PDF annotations on PDF page
    renderingSettings.DrawPdfAnnotations = true;

    // render PDF page
    Vintasoft.Imaging.VintasoftImage image = page.Render();

    // restore value of PdfRenderingSettings.DrawPdfAnnotations property
    renderingSettings.DrawPdfAnnotations = prevDrawPdfAnnotations;

    // return the image of PDF page
    return image;
}
