Release 2024.2.426 (2024 Q2)

When exporting a document with the .NET Framework implementation, only subsets of the used fonts are embedded in the document. This is currently not available in the Silverlight implementation, and it most probably won't be available in the .NET Standard implementation, as the current implementation is dependent on the WPF font classes. Provide API to plug similar logic when using different platforms as well.

This item wil handle the TrueType OpenType Font format. For the Compact Font Format (CFF) please follow: Export subset of Compact Font Format (CFF) fonts for platforms different than .NET Framework

This is the code used for merging:

        private  void MergeDifferentDocumentsPagesWithFixed()
        {
            string[] documentsToMerge =
            {
                "14301-STOCK_Proforma.pdf",
                "14302-STOCK_Proforma.pdf",
                "14303-STOCK_Proforma.pdf",
                "14304-STOCK_Proforma.pdf",
                "14305-STOCK_Proforma.pdf",
                "14330-STOCK_Proforma.pdf"
            };
            RadFixedDocument doc = new RadFixedDocument();
            PdfFormatProvider provider = new PdfFormatProvider();
            foreach (string current_item in documentsToMerge)
            {
                string path = @"..\..\Samples\" + current_item;
                RadFixedDocument docToMerge;
                if (!File.Exists(path))
                {
                    continue;
                }
                using (Stream stream = File.OpenRead(path))
                {
                    docToMerge = provider.Import(stream);
                }
                doc.Merge(docToMerge);
            }


            string outputFilePath = @"..\..\mergedFixed.pdf";
            File.Delete(outputFilePath);

Currently, a NullReferenceException is thrown because of the incorrect structure. 

As a workaround, the exception can be handled using the Handling Exceptions mechanism.

Update:
When importing documents with invalid structure of path construction operators an InvalidGraphicOperandsCountException is thrown which could be handled using the Handling Exceptions mechanism.

PdfFormatProvider provider = new PdfFormatProvider();
provider.ImportSettings.DocumentUnhandledException += this.ImportSettings_DocumentUnhandledException;

private void ImportSettings_DocumentUnhandledException(object sender, DocumentUnhandledExceptionEventArgs e)
{
    if (e.Exception is InvalidGraphicOperandsCountException)
    {
        e.Handled = true;
    }
}

I have the following form:

From the screen shot above you can see that the line above 75 is perfectly ok i.e. it doesn't go and intersect with the lines of the 72

but when i perform the following code


            var InputFileWithInteractiveForms = "C:\\Users\\Abhishek.Shrestha\\Downloads\\Template\\form-ub04.pdf";
            var finaldPDFName = "C:\\Users\\Abhishek.Shrestha\\Downloads\\TestABCPDF\\output2322.pdf";
            List<byte[]> filledupForms = new List<byte[]>();
            PdfFormatProvider provider = new PdfFormatProvider();
                
                RadFixedDocument document = provider.Import(File.ReadAllBytes(InputFileWithInteractiveForms));

                var formfields = document.AcroForm.FormFields;

                var formFieldsCopy = new List<FormField>(document.AcroForm.FormFields);

                // Iterate over the copied form fields and replace the dot character in their names for solving merging issue
                foreach (var field in formFieldsCopy)
                {
                    field.Name = field.Name.Replace(".", "");
                }
                
               //added this as the values were being hidden by editable fields
                document.AcroForm.ViewersShouldRecalculateWidgetAppearances = true;

                filledupForms.Add(provider.Export(document));
                File.WriteAllBytes(finaldPDFName, provider.Export(document));

According to the PDF specification:
A clipping path operator (W or W*) may appear after the last path construction operator and before the path-painting operator that terminates a path object.

Invalid:

W                          % clipping path operator
0 0 m                     % start of the path construction
596 0 l
596 842 l
0 842 l
h                            % end of the path construction
n                            % path-painting operator
Valid:
0 0 m
596 0 l
596 842 l
0 842 l
h
W
n

Currently (in the invalid cases), the path construction is skipped on import.

Currently, when registering *.otf font file with FontsRepository.RegisterFont method an exception is thrown during the font creation. 

WORKAROUND:  The font file may be converted to TTF format (*.ttf) which is successfully registered. This conversion may be achieved with FontForge by opening the font file and then choosing File -> Generate Fonts -> TrueType -> Generate.

If  row has a property set on it (for example "hidden" or a style), but it does not otherwise have any cells in it, the application might run into an infinite loop. The xml will look like this:

	<sheetData>
		<row r="1" spans="1:2" x14ac:dyDescent="0.35">
			<c r="A1"><v>1</v></c>
			<c r="B1"><v>2</v></c>
		</row>
		<row r="2" spans="1:2" s="1" customFormat="1" x14ac:dyDescent="0.35"/>
	</sheetData>

The last row has formatting applied, so it is present as an element, but has no cells. This file (when the xml is not formatted) will cause an infinite loop on import.
