How to hyphenate text?
I generate an PDF file with iText in Java. My table columns have fixed widths. Text that is too long for one line is wrapped in the cell. But hyphenation is not used. The word "Leistungsscheinziffer" is shown as:
Leistungssc //Break here
heinziffer
final PdfPTable table = new PdfPTable(sumCols); table.getDefaultCell().setBorder(Rectangle.NO_BORDER); table.getDefaultCell().setPadding(4f); table.setWidths(widthsCols); table.setWidthPercentage(100); table.setSpacingBefore(0); table.setSpacingAfter(5); final Phrase result = new Phrase(text, font); result.setHyphenation(new HyphenationAuto("de", "DE", 2,2)); final PdfPCell cell = new PdfPCell(table.getDefaultCell()); cell.setPhrase(result); table.addCell(cell); ...
Hyphenator h = new Hyphenator("de", "DE", 2, 2); Hyphenation s = h.hyphenate("Leistungsscheinziffer"); System.out.println(s);
Normally hyphenation is set on the Chunk
level:
Chunk chunk = new Chunk("Leistungsscheinziffer");
chunk.setHyphenation(new HyphenationAuto("de", "DE", 2,2));
table.addCell(new Phrase(chunk));
If you want to set the hyphenation on the Phrase
level, you can do so, but this will only work for all subsequent Chunk
s that are added. It won't work for the content that is already stored inside the Phrase
. In other words: you need to create an empty Phrase
object and then add one or more Chunk
objects:
Phrase phrase = new Phrase();
phrase.setHyphenation(new HyphenationAuto("de", "DE", 2,2));
phrase.add(new Chunk("Leistungsscheinziffer"));
I've made an example based on your code (HyphenationExample); the word "Leistungsscheinziffer" is hyphenated in the resulting PDF: hyphenation_table.pdf.
Note: for this example to work, you need to add the itext-hyph-xml.jar
to your CLASSPATH. This jar contains the hyphenation rules for a wide array of languages.
