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
