This may cause either big distance between some glyphs, or overlapping glyphs.

Currently this operator is interpreted correctly only for Pattern colorspace. It also partially supports the rest of the colorspaces from R1 2018.

Available in R2 2018 Official Release Version.

The "g" and "G" operators are used for setting color with a single component.


Available in R1 2017 Release

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



Available in R2 2017 Release

OutOfMemoryException is thrown when generating PDF with many pages each of which contains images, as all of the document model data is in-memory.

The issue is fixed with the new PdfStreamWriter API. As an example, you may see the attached demo to the following feedback item:

Available in LIB version: 2017.1.320

Implement Find methods which enable the users to search for a concrete string/content/text in a Pdf document (RadFixedDocument).

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);

This would allow creating documents with preferences such us HideToolbar, HideMenubar, FitWindow, PrintScaling and all other viewer preferences specified in PDF format specification.

When images are added to the document with non-default quality (PdfExportSettings.ImageQuality different that ImageQuality.High) , they are re-encoded, which uses a lot of memory and may cause OutOfMemoryException for large images.
Workaround (works when inserting big JPEG images): In this case ImageQuality.High may be used and RadPdfProcessing will decode only the image headers to insert the image into the PDF file. As image pixels are not decoded with ImageQuality.High, there will be no OutOfMemoryException.

Measuring big paragraphs is time consuming and may be optimized.

Currently every text fragment is exported by specifying all its properties. When there are many fragments one after another we may skip specifying the properties for every single fragment. This will improve both memory and time consumption performance.

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.

The issue is reproducible only with nested tables - tables positioned inside some other table cell. When using simple tables the text is always wrapped and rendered correctly. This may be used as a workaround for scenarios which allow replacing nested tables with simple ones.

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

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

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

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 that is used to close, fill and then stroke a PDF path geometry.

Available in R3 2018 SP1 release.
