Font AutoSize Issue
I'm evaluating pdfbox for filling in form fields from a template pdf file.
>From what I can tell, pdfbox does not support autosize font. While it will retain the font size 0 setting, the text that is placed into the fields is not autosized (until you alter the value manually).
Option A:
Is there some kind of command to execute before saving the pdf to force it to autosize?
Option B:
Do some math and calculate a new font size. I've done this (see code below) but you obviously lose the ability to autosize if the user ends up modifying a value.
Is there a way to do this math and set the initial display font size but leave the DA alone with autosize set?
I'm guessing this would be done by setting some other COSName String similar to setting the COSName.DA. However, I can't find much information on these.
Any help is appreciated. Code is below;
//item.field_value is the value I'm sticking into the form field
if (field instanceof PDTextbox)
{
int len = item.field_value.length();
if (len>2)
{
COSDictionary dict = field.getDictionary();
COSString defaultAppearance = (COSString) dict.getDictionaryObject(COSName.DA);
if (defaultAppearance != null)
{
//split the DA to grab the font size
String[] da = defaultAppearance.getString().split(" ");
List<String> da2 = new ArrayList<String>();
//loop through and remove any empty strings
// because for some reason when the font size is 0 there is an empty extra string in the way
for(int x=0; x<da.length; x++)
{
if (da[x].length()!=0)
da2.add(da[x]);
}
//Move back to a String[] (I'm new to java)
da = da2.toArray(da);
if (da.length >= 2) //only process if there are at least two characters
{
if (da[1].equals("0")) //If font size is actually autosized
{
COSArray fieldAreaArray = (COSArray) dict.getDictionaryObject(COSName.RECT);
PDRectangle rect = new PDRectangle(fieldAreaArray);
float width = rect.getWidth();
int size = (int)(width / len * 1.92); //doing stupid math to estimate new font size
if (size > 12)
size = 12;
else if (size < 8)
size = 8;
String customSize = "/Helv " + size + " Tf 0 g";
dict.setString(COSName.DA, customSize); //Set the new font size here
field = new PDTextbox(acroForm, dict); //Create as a new field (as seen in other threads)
}
}
}
}
}
field.setValue(item.field_value); //Set the field value

please do so mentioning the field in question and the value you wanted to set.

Yes it is.

No, you don't need to wait for the RC. Some hours after the enhancements have been put in there will be a newer 2.0.0-SNAPSHOT available.

I know and I'm investigating how to fix that (I have the same issue with some test files I'm using but thought I commit anyway because of the improvements)

Re: Font AutoSize Issue
Posted by jarrod <xh...@yahoo.com.INVALID>.
Hello Maruan,
In regards to the AutoSize changes;
The text fits better (no longer is cutoff by the field boundaries) :). The text is higher than normal, as mentioned by another, but is sufficient for my use.
Unfortunately, when converting my project from 1.8.9 to the latest 2.0.0 snapshot, I've encountered some new problems. I will send those in a new email.
Thanks,
Jarrod

I'm not very familiar with software life cycle, will I
need to wait for the RC for a fix? If so, any guesses as to
when that might be?
I
committed some changes to the text formatting specially for
autosize text. You can either build from source or use the
snapshot as soon as it is available at http://pdfbox.apache.org/download.cgi#snapshots
<http://pdfbox.apache.org/download.cgi#snapshots>
Please let me know if it
improves the output you get.

Re: Font AutoSize Issue
Posted by jarrod <xh...@yahoo.com.INVALID>.
Hello Maruan,
I understand what you describing. Its unfortunate it isn't listed in the spec so everyone can be the same. I imagine the calculation could get quite complicated. Yes I can use a newer version. I'm not very familiar with software life cycle, will I need to wait for the RC for a fix? If so, any guesses as to when that might be?
Have a great weekend and thanks for the help!

Additionally, in my case the length of text can be fairly
dynamic and fixing a font could be problematic for users
doing manual data entry/correction. Thanks for your added
input. Hopefully Mr Sahyoun has a solution for us.
I had a quick look. The issue
is not that the autosizing doesn't work. It's the
difference in calculating the available field size.
Unfortunately, as this is not documented in the PDF spec one
has to compare the content generated by Adobe and handle it
from there. (e.g. Adobe adds padding to the fields bounding
box but only to a certain limit, there are some edge cases
….) Anyway, I think there will can achieve a result
which is closer to what Adobe achieves using the data file
and templates provided.
Do
you have to stay on 1.8.x or would you be able to work with
the 2.0.0-SNAPSHOT version? We are also planning to have an
RC out soon.
As I'm on
travel it will be start of next week until I can handle
it.

Re: Font AutoSize Issue

Evan,
I tested doing the same thing but decided it wasn't a very good solution in my case. There are a lot of fields to modify over multiple pages across numerous pdf's that are updated annually. Additionally, in my case the length of text can be fairly dynamic and fixing a font could be problematic for users doing manual data entry/correction. Thanks for your added input. Hopefully Mr Sahyoun has a solution for us.
Thanks,
Jarrod

I actually have seen the exact same
behavior in 1.8.9.
I dealt with it by just fixing the forms in Acrobat so that
the fonts have
a fixed size, because I did not have the time or the energy
to deal with
it. But autosized fonts definitely did not work for me when
filling out
forms in 1.8.9.
If it would be helpful and Jarrod does not have a good
example document I
would be happy to publish one of mine.
Thanks.

Re: Font AutoSize Issue
Posted by Evan Williams <ev...@zapprx.com>.
I actually have seen the exact same behavior in 1.8.9.
I dealt with it by just fixing the forms in Acrobat so that the fonts have
a fixed size, because I did not have the time or the energy to deal with
it. But autosized fonts definitely did not work for me when filling out
forms in 1.8.9.
If it would be helpful and Jarrod does not have a good example document I
would be happy to publish one of mine.
Thanks.

which version of PDFBox are you using? Do you have a sample empty PDF and filled out one together with some code how you do the form filling?
Both 1.8.9 and 2.0.0-SNAPSHOT should support autosizing.
