Breaking Change in Version 23.10 PageSettings.PrinterSettings.PaperSources not existing

Aspose.PDF Product Family
1

Hello,
in Aspose.PDF Version 23.10 you replaced all System.Drawing.Printing dependencies with Aspose.Pdf.Printing. In most cases it can simply be replaced. But we can’t find a substitution for PrinterSettings.PaperSources. The following code can’t be compiled with Version 23.10:

var paperSources = querypagesettingseventargs.PageSettings.PrinterSettings**.PaperSources**;
var paperSource = paperSources.Cast().SingleOrDefault(ps => ps.RawKind == paperSourceRawKind);
querypagesettingseventargs.PageSettings.PaperSource = paperSource;

Do you have any suggestions how to fix this breaking change. Thank you very much in advance.
Best Regards Fabian.

You can please use it like below:

Aspose.Pdf.Printing.PaperSource ps = new Printing.PaperSource();
ps.Kind = Printing.PaperSourceKind.Upper;
printerSettings.DefaultPageSettings.PaperSource = ps;

Hello Ali,
thank you for your fast reply. Unfortunatly the PaperSource.Kind is read only:

Indeed, the PaperSource instances from the System.Drawing.Printing namespace are generated by requesting the printer’s capabilities using native Windows API. As it’s non-portable, and we cannot access in our library, we cannot generate a PaperSources collection on the Aspose.Pdf.Printing.PrinterSettings Class.

So, as per request, the following public APIs will be changed in the v.24.02:

  • Public constructor PaperSource(PaperSourceKind kind, string name) is added and may be used in the following way:
// Create native System.Drawing.Printing.PrinterSetting to query the printer's capabilities
var nativeSettings = new System.Drawing.Printing.PrinterSettings();
nativeSettings.PrinterName = querypagesettingseventargs.PageSettings.PrinterSettings.PrinterName;

var paperSources = nativeSettings.PaperSources;
var paperSource = paperSources.Cast().SingleOrDefault(ps => ps.RawKind == paperSourceRawKind);

// Create Aspose.Pdf.Printing.PaperSource out of the native PaperSource
// Aspose.Pdf.Printing.PaperSourceKind mirrors values of the System.Drawing.Printing.PaperSourceKind to allow easier conversion between types
querypagesettingseventargs.PageSettings.PaperSource = new Aspose.Pdf.Printing.PaperSource((Aspose.Pdf.Printing.PaperSourceKind) paperSource.Kind, paperSource.SourceName);
  • New public static class Aspose.Pdf.Printing.PaperSources is created to provide a collection of predefined paper sources as its properties. It may be used in the following way:
querypagesettingseventargs.PageSettings.PaperSource = Aspose.Pdf.Printing.PaperSources.Cassette;
  • Public setter for the PaperSource.Kind property is added.
