Aspose.Page C++ XPS to JPG converter allows to convert XPS document to JPG image on Windows and Linux.
It is necessary to do several steps in order to perform XPS to JPG conversion:

1. Initialize an input stream for input XPS document.
2. Create an instance of XpsDocument from created earlier input stream.
3. Specify SmoothingMode, Resolution and other options of JpegSaveOptions.
4. Create an instance of ImageDevice.
5. Save XPS document as image with JPEG save options to an array of arrays of bytes. One array of bytes for one page of input document.
6. Save resulting 2-dimensional arrays of bytes to JPG files creating for every bytes array a new file output stream.

Following code snippet shows how to convert XPS to JPG files in C++:

    //Outut file 
    string outputFileName = dataDir + "XPStoImage_out.jpg";
    // Initialize XPS input stream
    using (Stream xpsStream = File.Open(inputFileName, FileMode.Open, FileAccess.Read))
    {
        // Load XPS document form the stream
        XpsDocument document = new XpsDocument(xpsStream, new XpsLoadOptions());
        // or load XPS document directly from file. No xpsStream is needed then.
        // XpsDocument document = new XpsDocument(inputFileName, new XpsLoadOptions());

        // Initialize options object with necessary parameters.
        JpegSaveOptions options = new JpegSaveOptions()
        {
            SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality,
            Resolution = 300,
            PageNumbers = new int[] { 1, 2, 6 }
        };

        // Create rendering device for image
        ImageDevice device = new ImageDevice();

        document.Save(device, options);

        // Iterate through document partitions (fixed documents, in XPS terms)
        for (int i = 0; i < device.Result.Length; i++)
            // Iterate through partition pages
            for (int j = 0; j < device.Result[i].Length; j++)
            {
                // Initialize image output stream
                using (Stream imageStream = System.IO.File.Open(Path.GetDirectoryName(outputFileName) +
                    Path.GetFileNameWithoutExtension(outputFileName) + "_" + (i + 1) + "_" + (j + 1) +
                    Path.GetExtension(outputFileName), System.IO.FileMode.Create, System.IO.FileAccess.Write))
                    // Write image
                    imageStream.Write(device.Result[i][j], 0, device.Result[i][j].Length);

Let’s consider JpegSaveOptions. Using this class we can assign different conversion parameters while converting XPS to JPG.

• SmoothingMode assigns a degree of smoothing for lines, curves and edges of filled areas, may be AntiAlias, HighQuality, HighSpeed and Default (none). Default value is HighQuality.
• Resolution controls resolution of resulting image. Default value is 96.
• TextRenderingHint assigns quality of text rendering, may be AntiAlias, AntiAliasGridFit, ClearTypeGridFit, SingleBitPerPixel, SingleBitPerPixelGridFit, SystemDefault. Default value in XPS to JPG conversion is AntiAliasGridFit.
• InterpolationMode defines algorithm that is used when scaling or/and rotating image, may be Bicubic, Bilinear, High, HighQualityBicubic, HighQualityBilinear, Low, NearestNeighbor and Default. Default value is HighQualityBicubic.
• PageNumbers represents an array of numbers of pages which will be saved to JPG.
