Corrupted document when exporting "Courier New" subset.

Workaround - fully embed the font:

pdfFormatProvider.ExportSettings.FontEmbeddingType = FontEmbeddingType.Full;

It seems the font that is rendered in Adobe is not the same. The document does not contain the font and Adobe and PdfViewer are fallbacking to different fonts.

This is the code for inserting the image: 

        static void Main(string[] args)
        {
            FixedExtensibilityManager.ImagePropertiesResolver = new ImagePropertiesResolver();

            //Telerik.Windows.Documents.Extensibility.JpegImageConverterBase defaultJpegImageConverter = new Telerik.Documents.ImageUtils.JpegImageConverter();
            //Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.JpegImageConverter = defaultJpegImageConverter;

            //Output("fyb-64.png", "output-working.pdf");
             Output("fyb.png", "output-broken.pdf");
        }
        private static void Output(string resourceName, string outputFileName)
        {
            var document = new RadFixedDocument();
            using (var editor = new RadFixedDocumentEditor(document))
            {
                Stream image = new FileStream(resourceName, FileMode.Open);

                var table = new Table
                {
                    LayoutType = TableLayoutType.FixedWidth,
                    Margin = new Thickness(10, 0, 0, 0),
                };

                var row = table.Rows.AddTableRow();
                var cell = row.Cells.AddTableCell();
                var block = cell.Blocks.AddBlock();
                block.InsertImage(image);
                editor.InsertTable(table);

                var pdfData = ExportToPdf(document);
                File.Delete(outputFileName);
                File.WriteAllBytes(outputFileName, pdfData);

                Process.Start(new ProcessStartInfo() { FileName = outputFileName, UseShellExecute = true });
            }
        }

        private static byte[] ExportToPdf(RadFixedDocument document)
        {
            byte[] pdfData;

            using (var ms = new MemoryStream())
            {
                var pdfFormatProvider = new PdfFormatProvider();
                pdfFormatProvider.Export(document, ms);
                pdfData = ms.ToArray();
            }

            return pdfData;
        }

Workaround: Instead of setting the ImagePropertiesResolver, set the JpegImageConverter: 

            Telerik.Windows.Documents.Extensibility.JpegImageConverterBase defaultJpegImageConverter = new Telerik.Documents.ImageUtils.JpegImageConverter();
            Telerik.Windows.Documents.Extensibility.FixedExtensibilityManager.JpegImageConverter = defaultJpegImageConverter;

Search for specific text in a PDF document  and you will notice that if the document is landscape, the SearchResult.GetWordBoundingRect method may return incorrect results. If the document is Portrait, the exact results are highlighted with the code snippet below: 

            PdfFormatProvider provider = new PdfFormatProvider();
            RadFixedDocument document = provider.Import(File.ReadAllBytes("Landscape.pdf"));

                TextSearch searchText = new TextSearch(document);
                TextSearchOptions searchOptions = new TextSearchOptions { UseRegularExpression=false, CaseSensitive=false, WholeWordsOnly = true };
                IEnumerable<SearchResult> matchResults = searchText.FindAll("sed", searchOptions);
                foreach (SearchResult resultItem in matchResults)
                {
                    Rect rect = resultItem.GetWordBoundingRect();

                   
                    RadFixedPage page = resultItem.GetResultPage();
                    FixedContentEditor editor = new FixedContentEditor(page);
                 
                    editor.GraphicProperties.FillColor = new RgbColor(125, 255, 0, 0);
                    editor.DrawRectangle(rect);
                }
            
            string outputFilePath = "result.pdf";
            File.Delete(outputFilePath);
            File.WriteAllBytes(outputFilePath, provider.Export(document));
