pdfbox getcharacterbyarticle()渲染最后一页的向量

我正在尝试使用以下代码获取文本详细信息(如坐标,宽度和高度)(从here中获取此解决方案),但输出仅来自最后一页的文本< / strong>即可。

代码

public static void main( String[] args ) throws IOException    {
        PDDocument document = null;
        String fileName = "apache.pdf"

        PDFParser parser = new PDFParser(new FileInputStream(fileName));
        parser.parse();

        StringWriter outString = new StringWriter();

        CustomPDFTextStripper stripper = new CustomPDFTextStripper();
        stripper.writeText(parser.getPDDocument(), outString);

        Vector<List<TextPosition>> vectorlistoftps = stripper.getCharactersByArticle();

        for (int i = 0; i < vectorlistoftps.size(); i++) {
            List<TextPosition> tplist = vectorlistoftps.get(i);
            for (int j = 0; j < tplist.size(); j++) {
                TextPosition text = tplist.get(j);
                System.out.println(" String "
                        + "[x: " + text.getXDirAdj() + ", y: "
                        + text.getY() + ", height:" + text.getHeightDir()
                        + ", space: " + text.getWidthOfSpace() + ", width: "
                        + text.getWidthDirAdj() + ", yScale: " + text.getYScale() + "]"
                        + text.getCharacter() +" Font "+ text.getFont().getBaseFont() + " PageNUm "+ (i+1));
            }
        }
} 

CustomPDFTextStripper 类:

class CustomPDFTextStripper extends PDFTextStripper
{
    //Vector<Vector<List<TextPosition>>> data = new Vector<Vector<List<TextPosition>>>();
    public CustomPDFTextStripper() throws IOException {
        super();
    }

    public Vector<List<TextPosition>> getCharactersByArticle(){
       // data.add(charactersByArticle);
        return charactersByArticle;
    }
}

我尝试将矢量添加到列表中,但是当调用 stripper()时,它会遍历所有页面,最后一页的详细信息存储在 charactersByArticle 中矢量,从而返回相同的。如何获取所有页面的信息?

答案 0 :(得分:0)

临时修复:

更改主要方法,将当前页面设置为结束页面并获取文本信息。不过不是一个好主意。

 for (int page = 0; page < pageCount; page++)
                    {
        stripper.setStartPage(0);
        stripper.setEndPage(page + 1);
        stripper.writeText(parser.getPDDocument(), outString);
        Vector vectorlistoftps = stripper.getCharactersByArticle();
        PDPage thisPage = stripper.getCurrentPage();
        for (int i = 0; i < vectorlistoftps.size(); i++) {
                List<TextPosition> tplist = vectorlistoftps.get(i);
        }
    }
