Hi All iText bods,
I'm currently developing an application
which uses iText to merge text and graphics into a new PDF file. I'm
90% there and am impressed with how easy it has been so far, but I am stuck
with two points which I hope someone can answer:
Question 1: Within Adobe LiveCycle
you can add a variable to the form using the: File | Form Properties
| Variable tab. So for example I've added a variable called "foo"
with a value of "bar".
How
can I access the value of this variable within iText. I basically
am using iText to merge bits of information together (images and text)
and using the template to control how this is done. I've tried using
a form field and this works fine but is a bit hacky and the variable facility
seems like a more elegant solution.
Question2: When replacing text into
a form how can I detect if the text fits, and thus if it does not reduce
the font size of the field until it does fit for example?
I
can easily setup various field in the form so I can control the text to
some extent, i.e. setup a field to force the text to crop or wrap. But
if one of my users specifies a text box and wants the text to shrink to
fit. I'm currently assuming if I can find the size of the box (which
I already can with AcroFields:getFieldPositions() ) and then the string
width (which I cannot) then I can reduce the font size until it fits using
AcroFields:setFieldProperty().
I guess for this I do not need to know
the width of the string I just need to know: Is the field property
set to shrink to fit? and if so does the string fit? If not reduce
the font little and try again.
Hope this all makes sense.
Thanks in advance.
Jim
