hello sir,
with the help of the piece of code given by you,i have been working on a doc
file to get the font size etc.
HWPFDocument doc = new HWPFDocument(new FileInputStream(new
File("C:\\temp\\test.doc")));
Range range = doc.getRange();
int numCharRuns = doc.numCharacterRuns();
CharacterRun charRun = null;
for(int i = 0; i < numCharRuns; i++) {
charRun = doc.getCharacterRun(i);
}
as i parse through the doc file and store each paragraph in an array of
strings,i would like to know the font size of each paragraph,so that i will
be able to know whether it is a heading or some text under a heading
etc.with the help of the methods present in the api,i was able to know the
different font size's present in the doc file,but unable to associate them
with the text.in the piece of code given by you,i was unable to find the
method numCharacterRuns(),so please mention the class name in which it is
present.
thank you.
