如何使用 PDFBox 使用 Header 字体大小阅读 PDF 部分？

Question

I am trying to read PDF documents and I need them to be separated by sections using header font size or font and font size I currently have it implemented based on the answer of this post . But due to my PDF having the same font for header and the sub-header I need to modify the code so it would search based on font size or both.

    List<TextSectionDefinition> sectionDefinitions = Arrays.asList(
            new TextSectionDefinition("Section", x -> x.get(0).get(0).getFont().getName().contains("Calibri,Bold"), TextSectionDefinition.MultiLine.multiLineHeader, true)
    );

    document.getClass();
    PDFTextSectionStripper stripper = new PDFTextSectionStripper(sectionDefinitions);
    stripper.getText(document);

    System.out.println("Sections:");
    List<String> texts = new ArrayList<>();
    for (TextSection textSection : stripper.getSections()) {
        String text = textSection.toString();
        System.out.println(text);
        texts.add(text);
    }

    return ResponseEntity.ok(texts);

My problem stems if I try to use getFontSize instead of getFont it doesn't allow any parameters to be entered, in my case 16 (font size).

Answer 1

In the answer you refer to there are text section definitions like this:

new TextSectionDefinition("Titel",
    x->x.get(0).get(0).getFont().getName().contains("CMBX12"),
    MultiLine.singleLine,
    false)

I assume your remark

if I try to use getFontSize instead of getFont it doesn't allow any parameters to be entered, in my case 16

indicates that you want to exchange the lambda expression in the second parameter

x->x.get(0).get(0).getFont().getName().contains("CMBX12")

by something that tests the font size. Thus, have you tried replacing it by

x->x.get(0).get(0).getFontSize() == 16

or

x->x.get(0).get(0).getFontSizeInPt() == 16

or

x-> {
    float size = x.get(0).get(0).getFontSizeInPt();
    return size > 15 && size < 17;
}

yet?
