 InvalidCastException when importing a file with missing space. The file contains no space between the objects declarations and the page content and this is why the exception occurs.

When importing a VariableContent widget with OpenType font, which fails to read the post table of the font file, a NullReferenceException is thrown when the RecalculateContent() method is called.

Workaround: Change the widget font:

foreach (Widget widget in textBoxField.Widgets)
{
    widget.TextProperties.Font = FontsRepository.Helvetica;
    widget.RecalculateContent();
}

The underline gets over the text when the line spacing is set to exact, spacing after is set to 0, and the font size is less than 12.

The calculations are wrong, leading to single lines split by the LineSpacing set. As a result, the content of the PDF document is laid out on a bigger number of pages.

Workaround: Change the LineSpacingType to HeightType.Auto.

The current implementation relies on valid cross-reference offsets in the PDF documents so that PDF objects are easily found and parsed. However, we may implement a mechanism for importing documents with invalid offsets for the objects inside the table.

NullReferenceException is thrown when importing a PDF document containing InlineImage with missing parameters

When the document contains Simple Font with predefined encoding and no ToUnicode mapping the text should be extracted with the following algorithm:

  • Map the character code to a character name according to the font’s Differences array.
  • Look up the character name in the Adobe Glyph List to obtain the corresponding Unicode value. 

Currently, the PdfProcessing library doesn't map the character code properly which leads to wrongly encoded text content.

Release LIB 2020.1.316 (03/16/2020)

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);
