Support of PDF/A_2U Standard

We have introduced new PDFA standard, PDF/A_2U, in Aspose.Pdf for .NET 16.12.0. We have included a new value PDF_A_2U in PdfFormt enum. Please check following code snippet for new feature.

string inFile = "Input.pdf";
string outFile = "Output.pdf";
string outLog = "log.xml";
Aspose.Pdf.Document doc = new Aspose.Pdf.Document(inFile);
PdfFormatConversionOptions opts = new PdfFormatConversionOptions(outLog, PdfFormat.PDF_A_2U, ConvertErrorAction.Delete);
doc.Convert(opts);
doc.Save(outFile);

Convert XML Stream using C#

Some of customers have requirements to render XML stream to PDF instead of file. So we have introduced a new constructor of BindXml() that support the Stream parameter.

string inXml = "sample.xml";
string inXslt = "sample.xslt";
string outFile = "output.pdf";
Aspose.Pdf.Document doc = new Aspose.Pdf.Document();
doc.BindXml(new FileStream(inXml, FileMode.OpenOrCreate), new FileStream(inXslt, FileMode.OpenOrCreate));
doc.Save(outFile);

Support of HTML Text Conversion in XML to PDF

Recently, we have introduced a new XML schema of Aspose.Pdf(new generator). XSD includes in MSI installer. We have introduced HTML text support in new XML schema with this release. Here is sample XML and code for the conversion:

Sample XML

<?xml version='1.0' encoding='utf-8'?>
<Document xmlns="Aspose.Pdf">
<Page>
<HtmlFragment>some text<Hyperlink URL="www.google.com" /></HtmlFragment>
</Page>
</Document>

Sample Code

string inXml = "sample.xml";
string outFile = "output.pdf";
Aspose.Pdf.Document doc = new Aspose.Pdf.Document();
doc.BindXml(inXml);
doc.Save(outFile);
