在itext中,我有一个块/短语/段落(我不介意哪个),我想在页面上的其他位置放置,例如在300 x 200.我该怎么做?

最后我写了自己的方法来做到这一点。

private void PlaceChunck(String text, int x, int y) {
        PdfContentByte cb = writer.DirectContent;
        BaseFont bf = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
        cb.SaveState();
        cb.BeginText();
        cb.MoveText(x, y);
        cb.SetFontAndSize(bf, 12);
        cb.ShowText(text);
        cb.EndText();
        cb.RestoreState();
    }

这是一个包含所有正确的套管和try / catch块的版本:

  private static void absText(String text, int x, int y) {
    try {
      PdfContentByte cb = writer.getDirectContent();
      BaseFont bf = BaseFont.createFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
      cb.saveState();
      cb.beginText();
      cb.moveText(x, y);
      cb.setFontAndSize(bf, 12);
      cb.showText(text);
      cb.endText();
      cb.restoreState();
    } catch (DocumentException e) {
      e.printStackTrace();
    } catch (IOException e) {
      e.printStackTrace();
    }
  }

我在这些方面做了一些事情,也许它会帮助别人:

ColumnText ct = new ColumnText(writer.getDirectContent());
ct.setSimpleColumn(left,bottom,right,top);
ct.setText(new Phrase("String"));
ct.go();

在我的情况下,只有这个解决方案运行良好。

PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream(FILE));

添加方法

private void addTextData(Document document, String text) {
        PdfContentByte cb = pdfWriter.getDirectContent();
        cb.beginText();
        try {
            BaseFont f_cn = BaseFont.createFont(BaseFont.HELVETICA, BaseFont.CP1252, BaseFont.NOT_EMBEDDED);
            cb.setFontAndSize(f_cn, 40);

            float requiredX = 50;
            float requiredY = 50;
            Paint paint = new Paint();
            paint.setTextSize(40);
            Typeface typeface=Typeface.createFromAsset(getAssets(), "Helvetica.ttf");
            paint.setTypeface(typeface);
            paint.setColor(Color.BLACK);
            paint.setStyle(Paint.Style.FILL);

            Rect result = new Rect();
            paint.getTextBounds(text, 0, text.length(), result);
            Log.i("Text dimensions", "Width: "+result.width()+"-Height: "+result.height());
            float calculatedY = document.getPageSize().getHeight() - result.height() - requiredY;
            cb.setTextMatrix(requiredX, calculatedY);
            cb.showText(text);
            cb.endText();
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
}

这对您有帮助。

希望这对您有所帮助! 这是我的代码...

DatabaseError

添加功能:

 Document document = new Document(PageSize.A4);
 PdfWriter writer = PdfWriter.getInstance(document, output);
 document.open();

 FixText("Add Your Text",400,700,writer,14);
 document.close();
