How can I truncate text within a bounding box?

问题

I am writing content to a PdfContentByte object directly using PdfContentByte.showTextAligned, I'd like to know how I can stop the text overflowing a given region when writing.

If possible it would be great if iText could also place an ellipsis character where the text does not fit.

I can't find any method on ColumnText that will help either. I do not wish the content to wrap when writing.

回答1:

Use this:

int status = ColumnText.START_COLUMN;
ColumnText ct = new ColumnText(cb);
ct.setSimpleColumn(rectangle);
status = ct.go();

Make sure that you define rectangle in a way so that only one line fits, use ColumnText.hasMoreText(status) to find out if you need to add an ellipsis character.
