When a document is imported the FontsRepository caches the created font instances for performance reasons. API should be provided for clearing the cached instances in order to reduce memory consumption.

We would like to search a PDF document for specific text and returns its position. We generate PDF reports using Telerik Reporting which contain placeholders that are replaced with images and text at run-time. It appears the logic has already been implemented, but the implementing classes (e.g., TextSearch, TextRecognizer) aren't accessible. Please consider making this capability available.

These permissions are defined on a document level and apply permission handlers. The permission handlers are similar to the security handlers but do not require the document to be encrypted. They are also used to determine which objects are to be included in the digest calculation used for the digital signature functionality.

According to the specification, the startfref keyword must be followed by the offset the xref table start on, defined on a new line. Some documents, however, have both entries defined on the same line, which leads to InvalidOperationException with message "Stack empty" while importing. Make sure this case is handled in PdfProcessing as well.

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!

In principle, the blend function B (Cb , Cs ) is used in the compositing formula to customize the blending operation in Adobe transparency imaging model. The blending mode may define any function which yields another result color from the backdrop and source colors. This will allow overlaying objects on each other forming a transparency stack.

Support for the Blend Mode parameter of the external graphic state should be implemented.

Currently adding an Image content element with ImageSource instantiated with a PNG file format leads to NotSupportedException: 'Can not export other than Jpeg and Jpeg2000 and ImageQuality different than High', when exporting the document.

Support for adding PNG images and exporting to PDF should be implemented for PdfProcessing for .NET Standard scenario.

Support for exporting WMF (Windows Metafile) and EMF (Enhanced Metafile) images should be implemented.

Workaround: Convert the WMF images to PNG before exporting:
ImageSource imageSource = new ImageSource(new MemoryStream(this.ConvertWmfImageToPng(stream)));
document.Pages.AddPage().Content.AddImage(imageSource);
...
private byte[] ConvertWmfImageToPng(Stream wmfImageStream)
{
    byte[] pngBytes;
 
    using (MemoryStream pngImageStream = new MemoryStream())
    {
        System.Drawing.Image imageDrawing = System.Drawing.Image.FromStream(wmfImageStream);
        imageDrawing.Save(pngImageStream, System.Drawing.Imaging.ImageFormat.Png);
        pngBytes = pngImageStream.ToArray();
    }
 
    return pngBytes;
}

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.

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

A free text annotation displays text directly on the page. Unlike an ordinary text annotation, a free text annotation has no open or closed state; instead of being displayed in a pop-up window, the text is always visible.

RadPdfProcessing cannot find startxref keyword at the end of a document if the document contains many zero bytes at its end. NotSupportedException is thrown with "Startxref keyword cannot be found" message. 
Workaround: Trim the ending zero bytes before loading the document to PdfProcessing. Example showing this approach can be found in the following KB article:
http://www.telerik.com/support/kb/winforms/details/notsupportedexception-startxref-keyword-cannot-be-found-when-loading-pdf-file-in-radpdfviewer-for-winforms

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.
