Hi,

I'm new to QuickPdf and have a problem with the following task :

- I've got three fields "as a group" in a customer PDF and the text i need to put in them is large, so i must fit in the three fields (field1, field2 and field3).

The text is an enumeration like : item1, item2, item3, item4, item5, item6, item7, ...

I need to parse this text to the 3 fields depending on the fields width

ex :

Field1 : item1, item2, item3,

Field2 : item4, item5, item6,

Field3 : item7

I made something to do the job with iteration such as

GetTextWidth("item1, item2, item3, item4, item5, item6, item7") --> too long for field1

GetTextWidth("item1, item2, item3, item4, item5, item6") --> too long for field1

GetTextWidth("item1, item2, item3, item4, item5") --> too long for field1

GetTextWidth("item1, item2, item3, item4") --> too long for field1

GetTextWidth("item1, item2, item3") < Field1.width --> so OK for field1

and so on..for field2 and field3

It's ok even if there is often enough space to put an extra item on each field (1)

In my case GetFormFieldTextSize(field1) = 10 and FontSize() return 0.

Is there a way to set the FontSize() ?

How the GetTextWidth(string) works because FontSize() return 0 ?

(1) : Is there another function to do this test more accuratly ?

Have you got an idea or a tip to enhance my job ?

If i've got a bigger string to fit, I'd like to iterate and reduce the font size by decrement to finally fit the three fields...but how to test the string width with smaller font ?

Thanks in advance

Hi FLA,

Perhaps that "FontSize" returns 0 depends on the used font?:

Yes. You can set the textsize:

GetTextWidth won't work in your case 'cause it's based on "FontSize":

Cheers and welcome here,

Hi,

I've found a solution here : http://www.debenu.com/kb/converting-pixels-and-inches-to-postscript-points/

I needed to convert pixels to points to do my job.

Thanks
