Currently Run.Shading is not exported to PDF.

Note: This scenario is common when converting HTML to PDF, as Run.Shading is set when construct like <span style="background-color:#ffcc00;"> is used.

Workaround: Iterate all the Runs in the already imported HTML document and set their HighlightColor to Shading.BackgroundColor.LocalValue. Check this code snippet:

foreach (Run run in document.EnumerateChildrenOfType<Run>())
{
	if (!run.Properties.HighlightColor.HasLocalValue)
	{
		run.HighlightColor = run.Shading.BackgroundColor.LocalValue;
	}
}

This operator is used for drawing shading patterns.

Add support for MID function. MID returns a specific number of characters from a text string, starting at the position you specify, based on the number of characters you specify.

MID(text, start_num, num_chars)

A list of the supported functions is available at http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/functions

This function can be implemented as a custom function. Check the following resources for more details on how to achieve that:

- http://docs.telerik.com/devtools/document-processing/libraries/radspreadprocessing/features/formulas/custom-functions
- https://github.com/telerik/xaml-sdk/tree/master/Spreadsheet/WPF/CustomFunctions

This type of destinations is not supported and leads to InvalidCastException when importing such elements.

Add support for ToUnicode CMap stream.

A side effect of not supporting it is the following: exporting PDF document which, for example, contains German umlauts, to plain text, leads to wrong characters in the resulting text.

As possible workaround, the PdfFormatProvider instance of RadPdfViewer can be used to import the document. For example:

FormatProviderSettings settings = new FormatProviderSettings(ReadingMode.OnDemand);
PdfFormatProvider pdfViewerFormatProvider = new PdfFormatProvider(stream, settings);
 
RadFixedDocument document = pdfViewerFormatProvider.Import();
 
TextFormatProvider textFormatProvider = new TextFormatProvider();
String text = textFormatProvider.Export(document);

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

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.

Add APIs for creating and manipulating Chart objects.

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.

CMYK color may be set using SCN, scn, K and k operators.

Available support for import of CMYK colors in R3 2018 Official Release.

This feature is a must have for every business or enterprise!



Available in R2 2017 Release

This will enable printing with the following printing options: 

- Fit Sheet on One Page

- Fit All Columns on One Page

- Fit All Rows on One Page

- Custom automatic scaling


A possible implementation of a similar behavior is to use the PageSize property of WorksheetPageSetup and subtract the corresponding margin values (from the Margins property) from the width to calculate how many columns are fitting in some particular page size with 100% scale factor. 

Available in R2 2018 Official Release version.

Implemented import and export of IccBased, Indexed, Cmyk color spaces. Available in Q3 2015.

Available in R2 2018 Official Release version.

 This is content stream operator used for setting color in Device, CIE-based or Indexed color space.

Available in R2 2018 Official Release version.

Currently, when writing RadFixedPage the page instance reference is cached, as well as its content resources (images and fonts). This cache is important as it allows to reuse pages, images and fonts without writing them multiple times in the result PDF document. However, it needs to be optimized in order to consume less memory. 

The attached demo shows how to create 2500 pages with big images (different image on each page). With the current version, this demo consumes about 3 GB memory which may lead to OutOfMemoryException. With the optimization that will be introduced in LIB version, the same demo will consume about 20 MB memory for writing this big PDF document.

Available in LIB version: 2017.1.320

Currently, NotSupportedEncryptionException is thrown when PdfFileSource is initialized with an encrypted PDF file.
