itext positioning text absolutely
提问by Hyman
In itext I have a chunk/phrase/paragraph (I dont mind which) and I want to position some where else on the page e.g. at 300 x 200. How would I do this?
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一些位置，例如 300 x 200。我该怎么做？

In the end I wrote my own method to do it.
最后我写了我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();
}

Here's a version with all the correct casing and try/catch block:
这是一个包含所有正确大小写和 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();
}
}

I did something along these lines, maybe it will help others:
我做了一些沿着这些路线的事情，也许它会帮助其他人：
ColumnText ct = new ColumnText(writer.getDirectContent());
ct.setSimpleColumn(left,bottom,right,top);
ct.setText(new Phrase("String"));
ct.go();

In my case only this solution worked fine.
在我的情况下，只有这个解决方案工作正常。
PdfWriter pdfWriter = PdfWriter.getInstance(document, new FileOutputStream(FILE));
Add method
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();
}
}
This will help you for sure.
