At this point, the import logic cannot automatically repair such documents and a NullReferenceException is thrown while reading them. You could repair the invalid file using the project from the attachment.

Hello Telerik,

Last time we attempted this the <Viewbox> contents would not render and were empty upon xaml to pdf output. It would be great if you had this feature and we could move completely away from raster output to PDF for controls that contain Viewboxes. Otherwise we have really liked the PDF's created by the tool, the vector output is sharp as expected.

Thank you,

Patrick

These permissions are defined on a document level and apply permission handlers. The permission handlers are similar to the security handlers but do not require the document to be encrypted. They are also used to determine which objects are to be included in the digest calculation used for the digital signature functionality.

According to the specification, the startfref keyword must be followed by the offset the xref table start on, defined on a new line. Some documents, however, have both entries defined on the same line, which leads to InvalidOperationException with message "Stack empty" while importing. Make sure this case is handled in PdfProcessing as well.

In principle, the blend function B (Cb , Cs ) is used in the compositing formula to customize the blending operation in Adobe transparency imaging model. The blending mode may define any function which yields another result color from the backdrop and source colors. This will allow overlaying objects on each other forming a transparency stack.

Support for the Blend Mode parameter of the external graphic state should be implemented.

Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:
ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));
document.Pages.AddPage().Content.AddImage(imageSource);
...
private byte[] ConvertWmfImageToPng(Stream wmfImageStream)
{
    byte[] pngBytes;
 
    using (MemoryStream pngImageStream = new MemoryStream())
    {
        System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
        imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);
        pngBytes = pngImageStream.ToArray();
    }
 
    return pngBytes;

Documents can be signed using the end certificate of a certificate chain, instead of the whole chain. This improves the performance of the signing.
