Aspose.Page .NET XPS Merge allows to merge XPS files to XPS document with using of any language supported by .NET platform: C#, VB, J#.
It is necessary to do several steps in order to perform XPS merge:

1. Initialise an XpsDocument with the primary XPS file, e.g., var document = new XpsDocument("first.xps");.
2. Define a string array containing the paths of the additional XPS files to merge, for example:

   string[] additionalXps = { "second.xps", "third.xps" };

3. Add each additional XPS to the document (e.g., foreach (var file in additionalXps) document.AddPage(file);) and then save the merged XPS:

   document.Save("merged.xps");

The following code snippet shows how to merge XPS files in C#:

// Merge several XPS files to one XPS document.

// Load XPS document from XPS file
XpsDocument document = new XpsDocument(DataDir + "input.xps", new XpsLoadOptions());

// Create an array of XPS files that will be merged with the first one
string[] filesToMerge = new string[] { DataDir + "Demo.xps", DataDir + "sample.xps" };

// Merge XPS files to output XPS document
document.Merge(filesToMerge, OutputDir + "mergedXPSfiles.xps");

See XPS merge in Java and C++.

Aspose.Page .NET XPS Merge also allows to merge XPS files to PDF document.
It is necessary to do several steps in order to perform XPS to PDF merge:

1. Initialise an XpsDocument with the primary XPS file, e.g., var document = new XpsDocument("first.xps");.
2. Define a string array with the paths of the additional XPS files to merge, for example:

   string[] additionalXps = { "second.xps", "third.xps" };

3. Create a PdfSaveOptions instance and configure conversion options, e.g.:

   var pdfSaveOptions = new PdfSaveOptions();
   pdfSaveOptions.TextCompression = PdfTextCompression.Flate;
   pdfSaveOptions.ImageCompression = PdfImageCompression.Auto;
   pdfSaveOptions.JpegQualityLevel = 90;

4. Add each additional XPS to the document (e.g., foreach (var file in additionalXps) document.AddPage(file);) and save the result as PDF:

   document.Save("merged.pdf", pdfSaveOptions);

The following code snippet shows how to merge XPS files to PDF document in C#:

// Merge several XPS files to one PDF document.

// Load XPS document from the XPS file
XpsDocument document = new XpsDocument(DataDir + "input.xps", new XpsLoadOptions());

// Initialize options object with necessary parameters.
Aspose.Page.XPS.Presentation.Pdf.PdfSaveOptions options = new Aspose.Page.XPS.Presentation.Pdf.PdfSaveOptions()
{
    JpegQualityLevel = 100,
    ImageCompression = Aspose.Page.XPS.Presentation.Pdf.PdfImageCompression.Jpeg,
    TextCompression = Aspose.Page.XPS.Presentation.Pdf.PdfTextCompression.Flate
};

// Create an array of XPS files that will be merged with the first one
string[] filesToMerge = new string[] { DataDir + "Demo.xps", DataDir + "sample.xps" };

// Merge XPS files to output PDF file
document.MergeToPdf(filesToMerge, OutputDir + "mergedXPSfiles.pdf", options);

See XPS merge in Java and C++.

Let’s consider PdfSaveOptions. Using this class we can assign different conversion parameters while merging XPS files to PDF.

• JpegQualityLevel controls a quality of images in PDF document if ImageCompression algorithm is JPEG and can be from 0 to 100.
• ImageCompression algorithm encapsulated in PdfImageCompression Enumeration, may be Run Length Encoding (RLE), Flate, Lempel-Ziv-Welch (LZW) with base or optimized pedictor, JPEG , none (raw image bytes) and auto (the most appropriate compression for each image). Default is auto compression.
• TextCompression algorithm encapsulated in PdfTextCompression Enumeration, may be Run Length Encoding (RLE), Flate, Lempel-Ziv-Welch (LZW) and none. Default value in XPS to PDF merging is Flate.
• EncryptionDetails encapsulated in PdfEncryptionDetails. It allows setting encryption algorithm, permisions, owner and user passwords for PDF document.
• OutlineTreeExpansionLevel and OutlineTreeHeight controls view of document outline.
