How to move text written in Type 3 Font from one p

问题:

I have a pdf which include text written in Type 3 Font.

I want to get some text from it and write it into other pdf in exactly same shape.

I am using itext. Please give me a tip.

edit: I attached my code.

DocumentFont f = renderInfo.getFont(); 
String str = renderInfo.getText();
x = renderInfo.getBaseline().getStartPoint().get(Vector.I1);

In this code, I want to write str into x value position. In Type 3 Font, is it work?

You can copy parts of one page to a new one using code like this:

    InputStream resourceStream = getClass().getResourceAsStream("from.pdf");
    PdfReader reader = new PdfReader(new FileOutputStream("from.pdf"));
    Rectangle pagesize = reader.getPageSizeWithRotation(1);
    Document document = new Document(pagesize);
    PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream("areaOfFrom.pdf"));
    document.open();

    PdfContentByte content = writer.getDirectContent();
    PdfImportedPage page = writer.getImportedPage(reader, 1);

    content.saveState();
    content.rectangle(0, 350, 360, 475);
    content.clip();
    content.newPath();
    content.addTemplate(page, 0, 0);
    content.restoreState();

    document.close();
    reader.close();

This turns your

into

Unfortunately, though, that hidden content is merely... hidden... but it is still there. You can especially mark the lines with that hidden text and try to copy&paste them.

If you want to completely remove that hidden text (or start out by merely copying the desired text), you have to inspect the content of the imported page and filter it. I'm afraid iText does not yet explicitly support something like that. It can be done using the iText lowlevel API but it is quite some work.
