Aspose.Page C++ XPS merger allows to merge XPS files to XPS document on Windows and Linux.
It is necessary to do several steps in order to perform XPS merge:
- Create an instance of XpsDocument from the first XPS file.
- Create an array of XPS files that will be merged with the first one.
- Merge (by Merge) XPS files with created document and save it.
The following code snippet shows how to merge XPS files in C++:
1 // The path to the documents directory.
2 System::String dataDir = RunExamples::GetDataDir_WorkingWithDocumentMerging();
3
4 // Load XPS document from XPS file
5 System::SharedPtr<XpsDocument> document = System::MakeObject<XpsDocument>(dataDir + u"input.xps", System::MakeObject<XpsLoadOptions>());
6
7 // Create an array of XPS files that will be merged with the first one
8 System::ArrayPtr<System::String> filesToMerge = System::MakeArray<System::String>({dataDir + u"Demo.xps", dataDir + u"sample.xps"});
9
10 // Merge XPS files to output XPS document
11 document->Merge(filesToMerge, dataDir + u"mergedXPSfiles.xps");Aspose.Page C++ XPS merger allows also to merge XPS files into PDF document on Windows and Linux.
It is necessary to do several steps in order to perform XPS to PDF merge:
- Create an instance of XpsDocument from the first XPS file.
- Create an array of XPS files that will be merged with the first one.
- Specify TextCompression, ImageCompression, JpegQualityLevel, and other options of PdfSaveOptions.
- Merge (by MergeToPdf) XPS files with created document and save it as PDF with PDF save options.
The following code snippet shows how to merge XPS files to PDF document in C++:
1//For complete examples and data files, please go to https://github.com/aspose-page/Aspose.Page-for-C
2 // The path to the documents directory.
3 System::String dataDir = RunExamples::GetDataDir_WorkingWithDocumentMerging();
4
5 // Load XPS document form the XPS file
6 System::SharedPtr<XpsDocument> document = System::MakeObject<XpsDocument>(dataDir + u"input.xps", System::MakeObject<XpsLoadOptions>());
7
8 // Initialize options object with necessary parameters.
9 System::SharedPtr<Aspose::Page::XPS::Presentation::Pdf::PdfSaveOptions> options = System::MakeObject<Aspose::Page::XPS::Presentation::Pdf::PdfSaveOptions>();
10 options->set_JpegQualityLevel(100);
11 options->set_ImageCompression(Aspose::Page::XPS::Presentation::Pdf::PdfImageCompression::Jpeg);
12 options->set_TextCompression(Aspose::Page::XPS::Presentation::Pdf::PdfTextCompression::Flate);
13
14 // Create an array of XPS files that will be merged with the first one
15 System::ArrayPtr<System::String> filesToMerge = System::MakeArray<System::String>({dataDir + u"Demo.xps", dataDir + u"sample.xps"});
16
17 // Merge XPS files to output PDF file
18 document->MergeToPdf(filesToMerge, dataDir + u"mergedXPSfiles.pdf", options);Let’s consider
PdfSaveOptions. Using this class we can assign different conversion parameters while merging XPS 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.
