sorry sir,i overlooked the other mail which u sent me in which the code
HWPFDocument doc = new HWPFDocument(new FileInputStream(new
File("C;\\temp\\test.doc")));
Range = doc.getRange();
int numParagraphs = range.numParagraphs();
for(int i = 0; i < numParagraphs; i++) {
Paragraph para = range.getParagraph(i);
int numCharRuns = para.numCharacterRuns();
for(int j = 0; J , numCharRuns; j++) {
CharacterRun charRun = para.getCharacterRun(j);
..........
}
}
is given,using which i was able to find the font size of each paragraph.half
of my job is done.
thank you.
