We are pleased to announce the release of Aspose.Pdf for .NET 6.5.0. This release  includes some great new features such as setting background color of pages in PDF documents, determining which pages in a PDF document has background color set and support for attaching MP3 files. This release also improves the product’s performance when converting PDF files into XPS/TIFF format and extracting text and images from PDF. Aspose.Pdf for .NET 6.5 also includes support for transforming PDF files into HTML and other supported formats. We’ve also improved the file concatenation features.

Pass Documents from Class to Class without Saving

We have introduced a mechanism where you can use the single PDF document and pass it to various class objects present under Aspose.Pdf.Facades, without having to repeatedly save and open it. To facilitate this, we have locally added the Document property for almost all facades and extended them with new constructor. However, please note that not all facades work with Document directly.

For example PdfFileInfo only saves changes on invoking methods (SaveNewInfoWithXmp, SaveNewInfo) so has not been extended with the Document property. Document property can be used to access an inner document which is changed by Facade and then we can pass this Document object as an argument to another facade constructor in order to continue editing the same PDF document.

Please have a look at the code snippet below: it shows how PdfContentEditor and PdfAnnotationEditor can work in conjunction.

[C#] 
PdfContentEditor contentEditor= new PdfContentEditor();
contentEditor.BindPdf("input.pdf");
contentEditor.CreateText(newSystem.Drawing.Rectangle(100,100, 50, 50), 
              "Mine", "Some comment", false,"Comment", 1);

PdfAnnotationEditor annotationEditor= 
              new PdfAnnotationEditor(contentEditor.Document);
annotationEditor.ModifyAnnotationsAuthor(1,1, "Mine","Yours");
annotationEditor.Save(“UpdatedAnnotation.pdf”)
