Working with Pages in PostScript | C++

Add Pages to PS Document

Aspose.Page for C++ offers two ways of adding pages to PsDocument object.

The following code snippet creates a 2-paged PS document in 8 steps:

1. Create an output stream for the resulting PS file.
2. Create PsSaveOptions object with default options.
3. Create a 2-paged PsDocument with an already created output stream and save options.
4. Open the first page with the default page size of the document (A4 in Portrait orientation).
5. Close the page.
6. Open the second page with a new size.
7. Close the page.
8. Save the document.

    // The path to the documents directory.
    System::String dataDir = RunExamples::GetDataDir_WorkingWithPages();
    
    //Create output stream for PostScript document
    {
        System::SharedPtr<System::IO::Stream> outPsStream = System::MakeObject<System::IO::FileStream>(dataDir + u"document1.ps", System::IO::FileMode::Create);
        // Clearing resources under 'using' statement
        System::Details::DisposeGuard<1> __dispose_guard_0({ outPsStream});
        // ------------------------------------------
        
        try
        {
            //Create save options with A4 size
            System::SharedPtr<PsSaveOptions> options = System::MakeObject<PsSaveOptions>();
            
            // Create new 2-paged PS Document
            System::SharedPtr<PsDocument> document = System::MakeObject<PsDocument>(outPsStream, options, 2);
            
            //Add the first page
            document->OpenPage();
            
            //Add content
            
            //Close the first page
            document->ClosePage();
            
            //Add the second page with different size
            document->OpenPage(400.0f, 700.0f);
            
            //Add content
            
            //Close the second page
            document->ClosePage();
            
            //Save the document
            document->Save();
        }
        catch(...)
        {
            __dispose_guard_0.SetCurrentException(std::current_exception());
        }
    }

See working with the pages in PS documents in .NET or Java.

The following code snippet creates also a 2-paged PS document, but with 7 steps:

1. Create an output stream for the resulting PS file.
2. Create PsSaveOptions object with default options.
3. Create multi-paged PsDocument with already created output stream and save options. In this case, the first page is already opened and its size is the default page size of the document (A4 in Portrait orientation).
4. Close the page.
5. Open the second page with a new size.
6. Close the page.
7. Save the document. This way of adding pages is useful when the document has 1 page or it is unknown if it will be a 1- or 2-paged document.

    // The path to the documents directory.
    System::String dataDir = RunExamples::GetDataDir_WorkingWithPages();
    
    //Create output stream for PostScript document
    {
        System::SharedPtr<System::IO::Stream> outPsStream = System::MakeObject<System::IO::FileStream>(dataDir + u"document2.ps", System::IO::FileMode::Create);
        // Clearing resources under 'using' statement
        System::Details::DisposeGuard<1> __dispose_guard_0({ outPsStream});
        // ------------------------------------------
        
        try
        {
            //Create save options with A4 size
            System::SharedPtr<PsSaveOptions> options = System::MakeObject<PsSaveOptions>();
            
            //Set variable that indicates if resulting PostScript document will be multipaged
            bool multiPaged = true;
            
            // Create new multipaged PS Document with one page opened
            System::SharedPtr<PsDocument> document = System::MakeObject<PsDocument>(outPsStream, options, multiPaged);
            
            //Add content
            
            //Close the first page
            document->ClosePage();
            
            //Add the second page with different size
            document->OpenPage(500.0f, 300.0f);
            
            //Add content
            
            //Close the second page
            document->ClosePage();
            
            //Save the document
            document->Save();
        }
        catch(...)
        {
            __dispose_guard_0.SetCurrentException(std::current_exception());
        }
    }
