Hi All,
I have a web app that allows a user to enter text into a html text area. The
text they enter into the text area is used to generate a pdf file. One
requirement is that there is a limit on the amount of text entered.
After they enter their text and hit submit the a pdf file is created and it
is at this stage that we know if they have entered too much text. I am using
the class ColumnText and the method ct.go to determine of there was any
text that did not fit into the ColumnText object.
We would like to provide some real time validation using ajax. After each
word is entered we go off to the server and validate the text entered and
inform the user before they hit the submit button. I am want to know what
would be the least expensive way of doing this using Itext.
Is there a lot of over head in creating the following objects. Does anyone
know of a less expensive way of doing it
Document document = new Document(new
Rectangle(HORIZONTAL_PICTURE_PAGE_WIDTH, HORIZONTAL_PICTURE_PAGE_HEIGHT));
document.setMargins(0, 0, 0, 0);
pdfWriter = PdfWriter.getInstance(document, out);
document.open();
………………..
ColumnText ct = new ColumnText(pdfContentByte);
ct.setSimpleColumn(LEFT_MESSAGE_LOWER_X, LEFT_MESSAGE_LOWER_Y,
LEFT_MESSAGE_UPPER_X,
LEFT_MESSAGE_UPPER_Y,
MESSAGE_PADDING, MESSAGE_ALIGNMENT);
ct.addText(new Phrase(“Text to enter”,FONT));
if (ColumnText.NO_MORE_TEXT !=ct.go()) {
“TOO MUCH TEXT”
