Support for forms. The feature is named 'Interactive forms' in the PDF specification. Main scenarios to consider: - Reading of the data in the forms. - Writing data to the forms. 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.

Implement API for adding document outline (a.k.a bookmarks).
Paint content stream operator ("Do" in PDF specification) currently draws only Image XObjects. We should implement support for Form XObjects. Available in R2 2017 Release
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:
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.
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 new API will not read/delete the existing PDF pages content and this would allow performance and memory efficient realization of the following scenarios: - Merge PDF document pages from different PDF files. - Split PDF document pages to separate PDF files. - Append/Prepend PDF content to existing PDF pages. Moreover, as this approach will not require reading/deleting existing PDF page content, it will not depend on complex PDF features and will depend only on the PDF file structure. This will allow processing of PDF documents which use less common PDF features which are currently not supported by the existing PdfProcessing API. Available in R1 2017 Release
Implemented import and export of IccBased, Indexed, Cmyk color spaces. Available in Q3 2015. 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
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.
The MATCH function searches for a specified item in a range of cells and returns the relative position of the item found in this range. 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/CustomFunctions Available in R3 2017 Official Release Version
Encryption Algorithm 4 is implemented for R1 2018 official release. This includes all encryptions except AES 256 which is related to Encryption Algorithm 5. For AES 256 you may vote and follow this feedback item: https://feedback.telerik.com/Project/184/Feedback/Details/240154-pdfprocessing-support-encryption-algorithm-5-with-aes-256
