It will be possible to add an SVG element in a RadFixedPage so that it can be exported to PDF via the RadPdfProcessing library.

Export should take into account JavaScript and produce PDF similar to the original page.

This missing functionality may be workaround by implementing and registering custom IPdfFilter implementation that decodes JPEG2000 images. The custom decoder may be registered with FiltersManager class and its implementation may be similar to RadPdfViewers JpxDecoder SDK example implementation:

- https://github.com/telerik/xaml-sdk/blob/master/PdfViewer/CustomDecoder/JpxDecoder.cs
- Use a custom JPXDecode filter with RadPdfViewer

Implement API for adding document outline (a.k.a bookmarks).

Currently, we support inserting png, jpg and other raster graphic images. Provide a way to insert image from SVG (vector graphic image format), by creating a FormSource from its parsed XML.

Paint content stream operator ("Do" in PDF specification) currently draws only Image XObjects. We should implement support for Form XObjects. 


Available in R2 2017 Release

Highlight annotations appear as highlights in the text of a document. When opened, they display a pop-up window containing the text of the associated note.

or there should be an optional parameter "bool AcceptNewlines" or "bool IgnoreNewlines"

Currently, this can be implemented like this:

private void InsertTextWithNewlines(Block block, string text)
{
    string[] lines = text.Split(new[] {"\r\n", "\r", "\n"}, StringSplitOptions.None);

    for (int i = 0; i < lines.Length; i++)
    {
       block.InsertText(lines[i]);
       if (i < lines.Length - 1)
       {
          block.InsertLineBreak();
       }
    }
}

When merging documents containing the same embedded font every time a document is merged the same font is repeatedly embedded in the merged document. This leads to very large files.

A possible workaround before this feature is developed could be to use the PdfProcessing model to import and merge the documents. After the documents are merged to iterate the document`s content in order to cache the fonts using their name and if there are duplicated names to set the already cached one (check the attached project). 

As a side note, the suggested workaround doesn't cover all possible cases (e.g. if there are fonts with a common name but different font sets (modified fonts or font subsets) this may lead to missing/different characters in the produced document). So in order to use this workaround, you will need to ensure the font names are unique for every different font.

When opened in Adobe Reader it says that the file "claims compliance". However, when verifying the compliance with some validation tools there seem to be some issues mainly related but not limited to fonts. 

• Coons patch meshes (type 6) construct a shading from one or more color
  patches, each bounded by four cubic Bézier curves.

The standard fonts listed at http://docs.telerik.com/devtools/wpf/controls/radpdfprocessing/concepts/fonts#standard-fonts cannot be embedded in a document. Using one of them prevents the document from complying with PDF/A standard.

Some PDF files have an additional content added before the file header (before %PDF-1.4 for example). This additional content makes all byte offsets in the document invalid, which causes the format provider to throw an exception.

At this point, to import a similar document it should be pre-processed so the content before the version header is removed before importing it.

When merging, only the widgets are copied but not their fields. This can lead to ArgumentNullException when exporting the document. Implement copying the fields and consider cases which include collision of names of the fields.

Workaround:
Repair the generated document using the following code:
foreach (Widget widget in this.pdfDocument.Annotations.Where(annot => annot.Type == AnnotationType.Widget))
{
    if (!this.pdfDocument.AcroForm.FormFields.Contains(widget.Field.Name))
    {
        this.pdfDocument.AcroForm.FormFields.Add(widget.Field);
    }
}
In case of Name collision, you can use the attached project or the attached project to the following feedback item to rename the duplicate fields: Provide a way to rename FormFields.
