Currently, PdfStreamWriter writes only PDF pages.

If we implement API for merging multiple pages or whole documents we would be able to preserve links between pages (which are currently being corrupted).

Merging whole documents would also allow preserving document properties (bookmarks, interactive forms, ...). For a more detailed list of the unsupported document properties you can refer to our documentation: https://docs.telerik.com/devtools/document-processing/libraries/radpdfprocessing/formats-and-conversion/pdf/pdfstreamwriter/features.

We may also implement API for adding initial document properties from some existing PDF file.

By specification, the InteractiveForm fields can have the same name if they are descendants of a common ancestor. Such fields are different representations of the same underlying field; they should differ only in properties that specify their visual appearance. When such a document is imported an ArgumentException: 'An item with the same key has already been added.' is thrown.

Release LIB 2019.3.1111 (11/11/2019)
If the font family name is defined using a language other than English, the font is not applied to the content. This also can affect the performance as the font is read but it is not registered in the FontsRepository.

We would like to search a PDF document for specific text and returns its position. We generate PDF reports using Telerik Reporting which contain placeholders that are replaced with images and text at run-time. It appears the logic has already been implemented, but the implementing classes (e.g., TextSearch, TextRecognizer) aren't accessible. Please consider making this capability available.

I was working on some acroforms and wherever I needed a space I kept on getting a different letter (Ê). On debugging the problem seems to be in the TryGetCharCode function of OpenTypeFontSource

Version: 2019.3.917

Below is copy of function

public override bool TryGetCharCode(int unicode, out int charCode)
        {
            bool result = false;
            ushort glyphId;
            charCode = CMap.MISSING_GLYPH_ID;
            if (this.TryGetGlyphId(unicode, out glyphId))
            {
                ushort uCharCode = CMap.MISSING_GLYPH_ID;
                CMapTable table = this.CMap.GetCMapTable(3, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                table = this.CMap.GetCMapTable(1, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                charCode = uCharCode;

                return result;
            }

            return false;
        }

The font used has 2 cmap tables: one with platformid of 3 and encodingid of 1, the other with platformid 1 and encodingid 0. According to https://docs.microsoft.com/en-us/typography/opentype/spec/cmap platform id 3 and encoding 1 is correct for windows so not sure why the first call to getcmaptable looks for encodingid 0.

Second of all even if I change it to the following

CMapTable table = this.CMap.GetCMapTable(3, 1);

if there is a second cmap with platformid of 1 whatever the result of the call with regards to platformid 3, the result will be overridden

I can say that if I add some checks so that if the first call succeeds it doesn't attempt the 2nd I do get the expected behaviour in the pdf and get spaces

 

As a note the FontFamily property of the OpenTypeFontSource is "Arial"

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.
