Description Diego Ercolani 2009-11-03 02:22:24 UTC

I don't have much experience with pdf forms but I found a kind of ducument
bakered by Acrobat that doesn't be rendered correctly in okular that uses
poppler as backend.
I opened a bug issue in bugs.kde.org
(https://bugs.kde.org/show_bug.cgi?id=212394) but they told that this should be
a backend (poppler) where I opened a bug report
(https://bugs.freedesktop.org/show_bug.cgi?id=24812) problem as the same issue
is in every opensource pdf
rendering engine that I tryied:
ghostscript
kpdf from kde3
xpdf
gimp


There are 2 problems:

-------------- 1st problem ---------------
ghostscript think that the font used by the document contains ArialMT:
gs -sDEVICE=x11 EstrattoConto_1256901690391.pdf

while acrobat reader 8 properties says more characters but not ArialMT (I'll
include Acrobat properties screenshot) - immagine1.jpeg
The same for okular (see attached immagine2.jpeg)

--------------2nd problem (MORE IMPORTANT) ---------------------
The document contain a form that is compiled to create the pdf from java Adobe
LiveCycle Designer 8.
Okular shows that there are forms but doesn't show anithing but the page
template.... (see immagine3.jpeg)
while acrobat shows correctly the form with prefilled fields.

The document is a "statement of account" for credit cards so it's a kind of
document that is important to be readable....

Comment 6 Alex Cherepanov 2009-11-03 05:54:43 UTC

1. The sample file uses Arial font and Ghostscript maps it to ArialMT.

2. The file depends on JavaScript and XML form. Ghostscript, currently,
doesn't support either one. Old versions of Adobe Acrobat (e.g. 5)
render the file like Ghostscript. (To check this one has to convert
xref stream to xref table first.)

Comment 7 Ken Sharp 2013-06-11 10:24:34 UTC

As far as I know we have no intention of supporting JavaScript or XML

Comment 8 Ken Sharp 2013-06-11 12:53:39 UTC

Henry has pointed out that I forgot to say that PDF forms and Javascript are both supported and under ongoing development with our MuPDF product. If you want to work with these kinds of files we would recommend using that over Ghostscript.
