Convert PostScript to PDF using C++

[ ]

Aspose.Page for C++ PS to PDF converter allows to convert PostScript (PS) file to PDF document on Windows and Linux.
It is necessary to do several steps in order to perform PS to PDF conversion:

  1. Initialize an input stream for input PS file.
  2. Initialize an output stream for output PDF document.
  3. Create an instance of PsDocument from created earlier input stream.
  4. Use PdfSaveOptions to specify AdditionalFontsFolder and SuppressError boolean value.
  5. Create an instance of PdfDevice from created earlier output stream.
  6. Save PostScript document as PDF with PDF save options.
  7. If SuppressErrors value was true, as it is by default, It is possible to see what errors were thrown during conversion of PS to PDF and saved in Exceptions list.

Following code snippet shows how to convert PS to PDF document in C++:

For complete examples and data files, please go to
// Initialize PDF output stream
System::SharedPtr<System::IO::FileStream> pdfStream = System::MakeObject<System::IO::FileStream>(outDir() + u"outputPDF_out.pdf", System::IO::FileMode::Create, System::IO::FileAccess::Write);
// Initialize PostScript input stream
System::SharedPtr<System::IO::FileStream> psStream = System::MakeObject<System::IO::FileStream>(dataDir() + u"", System::IO::FileMode::Open, System::IO::FileAccess::Read);
System::SharedPtr<PsDocument> document = System::MakeObject<PsDocument>(psStream);

// If you want to convert Postscript file despite of minor errors set this flag
bool suppressErrors = true;

//Initialize options object with necessary parameters.
System::SharedPtr<PdfSaveOptions> options = System::MakeObject<PdfSaveOptions>(suppressErrors);
// If you want to add special folder where fonts are stored. Default fonts folder in OS is always included.
options->set_AdditionalFontsFolders(System::MakeArray<System::String>({ u"{FONT_FOLDER}" }));

// Default page size is 595x842 and it is not mandatory to set it in PdfDevice
System::SharedPtr<Aspose::Page::EPS::Device::PdfDevice> device = System::MakeObject<Aspose::Page::EPS::Device::PdfDevice>(pdfStream);
// But if you need to specify size and image format use following line
//Aspose.Page.EPS.Device.PdfDevice device = new Aspose.Page.EPS.Device.PdfDevice(pdfStream, new System.Drawing.Size(595, 842));

	auto __finally_guard_0 = ::System::MakeScopeGuard([&psStream, &pdfStream]()

		document->Save(device, options);
	catch (...)

Let’s consider PdfSaveOptions. Using this class we can assign different conversion parameters while converting PS to PDF.

  • AdditionalFontsFolder specifies locations where to find fonts. System fonts folders are always included by default.
  • SuppressError controls behaviour of PS to PDF converter when non-critical errors are appeared. If value is true than it is possible to view a list of such errors after conversion in Exceptions field. Default value is true.
  • Debug allows outputting debug information to console. Default value is false.
