本文介绍如何使用spire.pdf for java将pdf转为符合pdf/a-1a, 2a, 3a, 1b, 2b和3b标准的pdf。

import com.spire.pdf.conversion.pdfstandardsconverter;
public class convertpdftopdfa {
    public static void main(string[] args) {
        //指定输入文档路径
        string inputfile = "c:/users/administrator/desktop/sample.pdf";
        //指定输出文档的存放文件夹
        string outputfolder = "c:/users/administrator/desktop/output/";
        //创建pdfstandardsconverter对象，传入输入文档路径
        pdfstandardsconverter converter = new pdfstandardsconverter(inputfile);
        //转换为pdfa1a
        converter.topdfa1a(outputfolder   "topdfa1a.pdf");
        //转换为pdfa1b
        converter.topdfa1b(outputfolder   "topdfa1b.pdf");
        //转换为pdfa2a
        converter.topdfa2a(outputfolder   "topdfa2a.pdf");
        //转换为pdfa2b
        converter.topdfa2b(outputfolder   "topdfa2b.pdf");
        //转换为pdfa3a
        converter.topdfa3a(outputfolder   "topdfa3a.pdf");
        //转换为pdfa3b
        converter.topdfa3b(outputfolder   "topdfa3b.pdf");
    }
}
