C++: Convert PDF to PDF/A or PDF/X

PDF/A and PDF/X are two subsets of PDF file formats that were created to standardize the use of PDF in different areas. The former, PDF/A format, is primarily used for the long-term preservation or archiving of electronic documents, while the latter, PDF/X format, is specifically designed for the reliable and accurate pre-print exchange of graphic data. This article will demonstrate how to programmatically convert PDF to PDF/A or PDF/X format using Spire.PDF for C++.

In addition, each standard defines several different levels of conformance. The following are the steps to convert PDF to PDF/A-1A, 2A, 3A, 1B, 2B and 3B compliant files.

• Create a PdfStandardsConverter instance, and pass in a sample PDF file as a parameter.
• Convert the sample file to PdfA1A conformance level using PdfStandardsConverter->ToPdfA1A() method.
• Convert the sample file to PdfA1B conformance level using PdfStandardsConverter->ToPdfA1B() method.
• Convert the sample file to PdfA2A conformance level using PdfStandardsConverter->ToPdfA2A() method.
• Convert the sample file to PdfA2B conformance level using PdfStandardsConverter->ToPdfA2B() method.
• Convert the sample file to PdfA3A conformance level using PdfStandardsConverter->ToPdfA3A() method.
• Convert the sample file to PdfA3B conformance level using PdfStandardsConverter->ToPdfA3B() method.

	PdfStandardsConverter* converter = new PdfStandardsConverter(inputFile.c_str());

	//Convert to PdfA1A
	converter->ToPdfA1A(L"Output/ToPdfA1A.pdf");

	//Convert to PdfA1B
	converter->ToPdfA1B(L"Output/ToPdfA1B.pdf");

	//Convert to PdfA2A
	converter->ToPdfA2A(L"Output/ToPdfA2A.pdf");

	//Convert to PdfA2B
	converter->ToPdfA2B(L"Output/ToPdfA2B.pdf");

	//Convert to PdfA3A
	converter->ToPdfA3A(L"Output/ToPdfA3A.pdf");

	//Convert to PdfA3B
	converter->ToPdfA3B(L"Output/ToPdfA3B.pdf");

	delete converter;
}

It restricts certain features of the PDF format to ensure that the file is suitable for high quality printing. The following are the steps to convert PDF to a PDF/X-1a:2001 standard-compliant file.

• Create a PdfStandardsConverter instance, and pass in a sample PDF file as a parameter.
• Convert the sample file to PDF/X-1a:2001 standards compliant file using PdfStandardsConverter->ToPdfX1A2001() method.

#include "Spire.Pdf.o.h";

using namespace Spire::Pdf;
using namespace std;
int main() {

	//Specify the input file
	wstring inputFile = L"Data\\Test.pdf";

	//Create a PdfStandardsConverter instance
	PdfStandardsConverter* converter = new PdfStandardsConverter(inputFile.c_str());

	//Convert to PDF/X-1a:2001
	converter->ToPdfX1A2001(L"Output/ToPdfX1A2001.pdf");
	converter->Dispose();
	delete converter;
}
