Although Lab color space is currently unsupported, the provider should not throw exceptions that break the whole file import.
Implement API for adding document outline (a.k.a bookmarks).
When there is long text that is out of the used cell range area, this text should be included in page splitting calculations.
Also, when a cell has text that overflows its width, the text is again clipped by the cell boundaries and is not visible in the exported PDF. In a similar case Excel exports the surrounding cells to ensure that the content is visible.
Workaround: Extend the used cell range to include all the cells which the text content spans.
The CropBox is currently not supported by RadFixedPage class and is not preserved on an Import-Export scenario with PdfFormatProvider. CropBox is also not supported by PdfPageSource class and it is not preserved by using PdfStreamWriter as well. This property should be implemented in both scenarios.
When documents are exported to PDF, the creation date and modification date are not expected, or, when the time zone is with negative offset, the documents are invalid (detected by validation tools).
Stencil color has to be preserved for images with ImageSource when ImageMask property set to true. Not preserving it results in wrong colors (for instance the image may be visualized as a black rectangle). Available in R1 2019 Official Release Version.
The tj operator is responsible for drawing text content. When such operator is left empty, the import throws NullReferenceException because of the missing operands. Available in LIB Version 2018.3.1022.
This operator modifies the current clipping path by intersecting it with the current path, using the even-odd rule to determine which regions lie inside the clipping path. Available in R3 2018 SP1 release.
This is content stream operator that is used to close, fill and then stroke a PDF path geometry. Available in R3 2018 SP1 release.
This type of fields is currently not supported: https://feedback.telerik.com/Project/184/Feedback/Details/249205 . However, the fields can be skipped and the other content can be imported without throwing an exception. Fix available in R3 2018 SP1 release.
When the string contained in a PdfHexString instance is empty, invoking ToString() leads to IndexOutOfRangeException. Available in R3 2018 SP1 release version.
A font descriptor can be used by several fonts. However, when first a TrueType font is imported, later trying to import a Cid font leads to InvalidCastException with the message: "Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontDescriptor' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.CidFontDescriptor'." Fix available in R3 2018 SP1 release.
CMYK color may be set using SCN, scn, K and k operators. Available support for import of CMYK colors in R3 2018 Official Release.
In this case, we should use a default alpha source value which is the opacity source.

The exception is reproduced only with specific custom fonts and is thrown by the ComputeSubset() method of the GlyphTypeface class with the following message: "file does not conform to the expected file format specification". However, we can handle the exception and export the font data using the base class. Fix available in LIB Version 2018.2.828.
The exception is thrown by System.Linq.Enumerable.Max method during the CidSet calculations. Fix available in LIB Version 2018.2.730.
