Currently, the SkiaImageFormatProvider considers the RadFixedPage.Size when creating the image. If the RadFixedPage.CropBox is specified, the developer can control what rectangle of the page to be displayed/printed. However, it is not considered when exporting to an image. Improving the SkiaImageFormatProvider to respect the CropBox as well will give the opportunity to crop just a certain region of the PDF page and save it as an image.

When an import of the attached PDF file is executed, the result is a file with vertically rotated images, as well as enlarged and distorted. This is part of the code executed in the final application. Do you have any idea why this is happening? Is there any suggested solution?
As a result of the imported file, other processes are executed, such as creating bookmarks and page numbering, but the result is incorrect when presenting the rotated images.
Please find attached a code snippet and the input and generated output file.
Thank you.
private static void TestPDF()
{
RadFixedDocument document;
Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider providerPdf = new();
using (Stream stream = System.IO.File.OpenRead("C:\\TMP\\Ejemplo1-Input.pdf"))
{
document = providerPdf.Import(stream);
byte[] output = providerPdf.Export(document);
System.IO.File.WriteAllBytes("C:\\TMP\\Ejemplo1-Output.pdf", output);
}
}

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));
Process.Start(new ProcessStartInfo() { FileName = outputFilePath, UseShellExecute = true });Landscape: wrong rectangles are highlighted
Portrait: correct rectangles are highlighted:

When Cyrillic culture is set an InvalidCastException is thrown.
Workaround: use English culture during the import process
System.Globalization.CultureInfo currentCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-EN");
PdfFormatProvider provider = new PdfFormatProvider();
RadFixedDocument document;
using (Stream stream = File.OpenRead("popup_dedetizacao_ok.pdf"))
{
document = provider.Import(stream);
}
System.Threading.Thread.CurrentThread.CurrentCulture = currentCulture;
For the RadPdfViewer control you can use a similar approach:
System.Globalization.CultureInfo currentCulture = System.Threading.Thread.CurrentThread.CurrentCulture;
System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("en-EN");
PdfFormatProvider provider = new PdfFormatProvider();
RadFixedDocument document;
using (Stream stream = File.OpenRead("popup_dedetizacao_ok.pdf"))
{
document = provider.Import(stream);
}
System.Threading.Thread.CurrentThread.CurrentCulture = currentCulture;
RadForm form = new RadForm();
RadPdfViewer radPdfViewer1 = new RadPdfViewer();
form.Controls.Add(radPdfViewer1);
radPdfViewer1.LoadElementTree();
radPdfViewer1.Dock = System.Windows.Forms.DockStyle.Fill;
radPdfViewer1.Document = document;
form.ShowDialog();

As Ghiath reported in the forum thread, I am seeing this same error.
I am using RadFixedDocument and am generating a PdfFormatProvider. As Ghiath mentioned it will work fine (weeks, months) and then it seems the the font file is locked and it cannot export.
System.IO.IOException: I/O error when opening file 'C:\WINDOWS\FONTS\MSYH.TTC'. System.Web.HttpUnhandledException (0x80004005): Exception of type 'System.Web.HttpUnhandledException' was thrown. ---> System.IO.IOException: I/O error when opening file 'C:\WINDOWS\FONTS\MSYH.TTC'. at MS.Internal.FontCache.FileMapping.OpenFile(String fileName) at MS.Internal.FontCache.FontSource.GetUnmanagedStream() at System.Windows.Media.GlyphTypeface.ComputeSubset(ICollection`1 glyphs) at Telerik.Windows.Documents.Fixed.Model.Fonts.CidType2Font.ComputeSubset(IEnumerable`1 usedCharacters) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontStream.CopyPropertiesFromOverride(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontStream.CopyPropertiesFrom(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontDescriptor.CreateFontFile(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontDescriptor.ExportFontFile(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.FontDescriptor.CopyPropertiesFrom(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.CidFontObject.CopyPropertiesFromOverride(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.CidFontObject.CopyPropertiesFrom(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Elements.Fonts.Type0FontObject.CopyPropertiesFromOverride(IPdfExportContext context, FontBase font) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Export.PdfExporter.WriteFontsFromContext(PdfWriter writer, IPdfExportContext context) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Export.PdfExporter.Export(IRadFixedDocumentExportContext context, Stream output) at Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.PdfFormatProvider.ExportOverride(RadFixedDocument document, Stream output) at Telerik.Windows.Documents.Common.FormatProviders.FormatProviderBase`1.Export(T document, Stream output)
It will throw the exception on the line where it is doing the export. The document is typically a multi-page document with images, etc. As I mentioned it might work fine for weeks and then once it fails the only solution is to recycle the web service.
