I would like to request an example of the RadPdfProcessing library utilizing a Line Chart similar to how the Bar Chart is drawn in this example. 

Additionally, it would be great if there was an example with multiple charts on one page.

Thank you!

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 the content of a page is rotated, each glyph is exported on a new line.

By the PDF format specification, CIDToGIDMap is optional. The default value is Identity. However when exporting CID Font with missing CIDToGIDMap property the analyzing tool causes the following warning message:

"PDF/A requires that a Type 2 CIDFont has a stream mapping from CIDs to glyph indices or the name Identity as its value."

When merging files the documents might have the same fonts embedded. Then the PdfProcessing should use only one of the fonts and skip embedding the second font in the resulting document.

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.

Documents can be signed using the end certificate of a certificate chain, instead of the whole chain. This improves the performance of the signing.

Allow the customers to insert DWG files in the PDF documents.

This request is to ask that the development team review the code inside the Documents for refactoring to see if certain things can be reduced (like Generics).

 

When using the Telerik UI for Xamarin and referencing the UI.for.Xamarin NuGet package, the assembly reference for the Telerik.Documents.Fixed.dll is added to the project. This increases the amount of code that is compiled when the Linker is only set to SDK only, thus breaking AOT compilation with LLVM enabled.

 

A few addition insights:

 

- When the project cannot set the Linker to SDK and User Assemblies

- When individually referencing DLLs for only what the project uses is an insufficient solution

- When installing sub-packages like Telerik.UI.for.Xamarin.DataGrid is an insufficient solution.

 

 

Thank you.

By specification, the document AcroForm contains fields with no parents. However, some documents may have child fields in the AcroForm. This leads to ArgumentException when importing the child and parent fields - 'An item with the same key has already been added.' since the child field is added twice.

When creating a GradientStop, an alpha channel of the color could be applied. However, this setting is not respected it the result document and the gradient is with full opacity.

Steps to reproduce:
1. Create a gradient with an alpha channel:

RadFixedDocument document = new RadFixedDocument();
RadFixedPage page = document.Pages.AddPage();
FixedContentEditor containerEditor = new FixedContentEditor(page);

LinearGradient linearGradient = new LinearGradient(new Point(0, 0), new Point(30, 30));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 207, 0), 0));
linearGradient.GradientStops.Add(new GradientStop(new RgbColor(10, 0, 102, 204), 1));

containerEditor.GraphicProperties.FillColor = linearGradient;
containerEditor.DrawRectangle(new Rect(10, 10, 48, 29));

2. Export the document to PDF

Observed: The alpha channel is not respected and the gradient is with full opacity

Implement functionality allowing to specify that when a table is split on multiple pages, a specific row should be shown on each page.

Workaround: in the attached demo projects.

Currently, similar scenario may be achieved by converting Tiff images to BitmapSource and inserting them to RadFixedPage as images by using FixedContentEditor.
Note: A sample approach how to achieve such functionality is demonstrated in the Converting Multi-page TIFF Images to PDF KB article.

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.

By specification the last line of the file contains only the end-of-file marker, %%EOF. When importing document with missing EOF, InvalidOperationException: 'Stack empty', is thrown.

The case is invalid according to the specification but all readers manage to open the document and allow editing its fields. The document can be also opened in RadPdfViewer but without the fields and the widgets.

Exported protected document containing SignatureField can not be opened even if the correct password is used. The same behavior is reproduced with empty document (without pages).

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).

Support conversion of XPS documents to PDF using RadPdfProcessing.
