Provide ability for working with comments in a spreadsheet document.

Watermark transparency is not imported correctly

Importing an XLS document containing header/footer definition without a specific placement causes an endless loop. 

The exception is thrown at Telerik.Windows.Documents.Core.Data.ValueMapper`2.GetToValue(TFrom value) with message 'Not supported from value: numTab'

When importing a document containing a specific image stream an exception is thrown.

Dear Team,

when I create a pdf with your components (RadFixedDocument, RadFixedPage, FixedContentEditor) I cannot add a "german umlaut" in that report because then it cannot be viewed in your own pdfviewer- control (the exception is: Error loading document: Position is out of range).

I tried to solve this in "creating/ loading" arial.ttf as external font (even this is weird as idea), but this also did not work.

What is your solution for that?

I bought the Telerik components basically for PDF processing, this simply needs to work...

Many thanks for an urgent update on that!

Best regards

Tobias

According to the .ZIP File Format Specification: BZIP2 is an open-source data compression algorithm developed by Julian Seward.

Current implementation relies on valid cross-reference offsets in the PDF documents so that PDF objects are easily found and parsed. However, we can implement a mechanism for repairing documents with invalid cross-reference tables.

The attached project shows how to repair the simplest case of cross-reference table by using RepairDocumentWithSimpleCrossReferenceTable method.

 Table with specified width in inches is not correctly exported when the size is set in inches (this is  done in the imported HTML) 

Workaround: set the table size in the code and remove the style.

foreach (Table table in document2.EnumerateChildrenOfType<Table>())
{
    table.LayoutType = TableLayoutType.FixedWidth;
    table.PreferredWidth = new TableWidthUnit(TableWidthUnitType.Fixed, 950);
}

RadPdfProcessing cannot find startxref keyword at the end of a document if the document contains many zero bytes at its end. NotSupportedException is thrown with "Startxref keyword cannot be found" message. 
Workaround: Trim the ending zero bytes before loading the document to PdfProcessing. Example showing this approach can be found in the following KB article:

Add support for Upper and Lower field switches  More info is available here: Formatting fields with switches

Here are the switches that should be supported:

First Name Upper: {MERGEFIELD FirstName \* Upper}
First Name Lower: {MERGEFIELD FirstName \* Lower}

Add support for all number switches.  More info is available here: Formatting fields with switches

Here are the switches that should be supported:

Amount \# $,0.00: {MERGEFIELD FirstAmount \# $,0.00}
Amount \# $#,###,###: {MERGEFIELD FirstAmount \# $#,###,###}
Amount \*CardText:  {MERGEFIELD \\*CardText}
Amount \*DollarText:  {MERGEFIELD \\*DollarText}
Integer \*alphabetic: {MERGEFIELD \\*alphabetic}
Integer \* ALPHABETIC: {MERGEFIELD FirstInteger \* ALPHABETIC}
Integer \* OrdText: {MERGEFIELD FirstInteger \* OrdText}
Integer \* Ordinal: {MERGEFIELD FirstInteger \* Ordinal}
Integer \* roman: {MERGEFIELD FirstInteger \* roman}

When importing such documents an InvalidDataException (Unknown compression method <method-name>) is thrown.

According to the current .ZIP File Format Specification these methods are 7, 11, 13, 15, and 17.

Compression method:

        0 - The file is stored (no compression)
        1 - The file is Shrunk
        2 - The file is Reduced with compression factor 1
        3 - The file is Reduced with compression factor 2
        4 - The file is Reduced with compression factor 3
        5 - The file is Reduced with compression factor 4
        6 - The file is Imploded
        7 - Reserved for Tokenizing compression algorithm
        8 - The file is Deflated
        9 - Enhanced Deflating using Deflate64(tm)
       10 - PKWARE Data Compression Library Imploding (old IBM TERSE)
       11 - Reserved by PKWARE
       12 - File is compressed using BZIP2 algorithm
       13 - Reserved by PKWARE
       14 - LZMA
       15 - Reserved by PKWARE
       16 - IBM z/OS CMPSC Compression
       17 - Reserved by PKWARE
       18 - File is compressed using IBM TERSE (new)
       19 - IBM LZ77 z Architecture 
       20 - deprecated (use method 93 for zstd)
       93 - Zstandard (zstd) Compression 
       94 - MP3 Compression 
       95 - XZ Compression 
       96 - JPEG variant
       97 - WavPack compressed data
       98 - PPMd version I, Rev 1
       99 - AE-x encryption marker (see APPENDIX E)

Exception when copying worksheet that contains a shape

When importing a document containing an inline image that starts with spaces a NullReferenceException is thrown.

Implement async PDF conversion from RadFlowDocument and Workbook

If a worksheet spans more than one page, you can print row and column headings or labels (also called print titles) on every page to ensure that the data is properly labeled.

Wrongly exported image size when the size of the shape is different than the original image size

OpenDocument Format is an open format for many software supported like OpenOffice, I hope the Telerik Document Processing libraries could support for import/export format.

The Open Document Format for Office Applications (ODF), also known as OpenDocument, is an open standard file format for spreadsheets, charts, presentations, and word processing documents using ZIP-compressed[6] XML files.

The most common filename extension for spreadsheets is .ods.
