When merging, only the widgets are copied but not their fields. This can lead to ArgumentNullException when exporting the document. Implement copying the fields and consider cases which include collision of names of the fields.

Workaround:
Repair the generated document using the following code:
foreach (Widget widget in this.pdfDocument.Annotations.Where(annot => annot.Type == AnnotationType.Widget))
{
    if (!this.pdfDocument.AcroForm.FormFields.Contains(widget.Field.Name))
    {
        this.pdfDocument.AcroForm.FormFields.Add(widget.Field);
    }
}
In case of Name collision, you can use the attached project or the attached project to the following feedback item to rename the duplicate fields: Provide a way to rename FormFields.

I am using the trial version of telerik for xamarin for .net core which was released last year, to convert pdf to text. Our service is hosted in Azure. The text which I get back, in certain cases the spaces are missing (say for example instead of 'I [am] here', it displays 'I[am]here'. This happens randomly. 

The code which we have used is as follows -

byte[] pdfBinary = Convert.FromBase64String(inputString);

 TextFormatProviderSettings textFormatProviderSettings = new TextFormatProviderSettings("\r\n", " ");
         
 var textFormatProvider = new TextFormatProvider();
 var pdfFormatProvider = new PdfFormatProvider();

 RadFixedDocument document = pdfFormatProvider.Import(pdfBinary);
 result = textFormatProvider.Export(document, textFormatProviderSettings);

Implement Replace method(s) which enable the users to replace a concrete string/content/text in a PDF document (RadFixedDocument).

Workaround: 
Check the sample project attached ("RemoveText.zip") that demonstrates how to remove text separated into several text fragments.

Hello Telerik,

Last time we attempted this the <Viewbox> contents would not render and were empty upon xaml to pdf output. It would be great if you had this feature and we could move completely away from raster output to PDF for controls that contain Viewboxes. Otherwise we have really liked the PDF's created by the tool, the vector output is sharp as expected.

Thank you,

Patrick

Add support for movie annotations.

The values of rotated widgets on a rotated page are invisible after exporting them. The value can be seen only while editing a field.

RadPDfProcessing: Exception when parsing a Tiling pattern with non-rgb color.

If ImageInline's size is set through its Size property and not through Height or Width, the given size is not respected on export.

When there is a destination object in a RadFixedDocument and it doesn't have page set (it is null), an exception is thrown. However, this is supported by Adobe and it is not forbidden in the Pdf specification.

Add support for R16 color space

WinAnsiEncoding it is imported as StandardEncoding since WinAnsiEncoding is still not implemented in RadPdfProcessing. 

Add support for documents with an invalid stream cross-reference table

This operator is used for drawing shading patterns.

The exception is thrown with the message "Password is not correct" even when the user password is correct. This issue occurs for specific encryption algorithm parameters only.

If the font family name is defined using a language other than English, the font is not applied to the content. This also can affect the performance as the font is read but it is not registered in the FontsRepository.

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.

By specification when a form field is merged with the dictionary of the widget annotation, a Kids parameter can be existent if there are more than one widget annotations for that field. Support for importing such a fields should be added. 

I was working on some acroforms and wherever I needed a space I kept on getting a different letter (Ê). On debugging the problem seems to be in the TryGetCharCode function of OpenTypeFontSource

Version: 2019.3.917

Below is copy of function

public override bool TryGetCharCode(int unicode, out int charCode)
        {
            bool result = false;
            ushort glyphId;
            charCode = CMap.MISSING_GLYPH_ID;
            if (this.TryGetGlyphId(unicode, out glyphId))
            {
                ushort uCharCode = CMap.MISSING_GLYPH_ID;
                CMapTable table = this.CMap.GetCMapTable(3, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                table = this.CMap.GetCMapTable(1, 0);
                if (table != null)
                {
                    result = table.TryGetCharId(glyphId, out uCharCode);
                }

                charCode = uCharCode;

                return result;
            }

            return false;
        }

The font used has 2 cmap tables: one with platformid of 3 and encodingid of 1, the other with platformid 1 and encodingid 0. According to https://docs.microsoft.com/en-us/typography/opentype/spec/cmap platform id 3 and encoding 1 is correct for windows so not sure why the first call to getcmaptable looks for encodingid 0.

Second of all even if I change it to the following

CMapTable table = this.CMap.GetCMapTable(3, 1);

if there is a second cmap with platformid of 1 whatever the result of the call with regards to platformid 3, the result will be overridden

I can say that if I add some checks so that if the first call succeeds it doesn't attempt the 2nd I do get the expected behaviour in the pdf and get spaces

 

As a note the FontFamily property of the OpenTypeFontSource is "Arial"
