Steps to Reproduce:
1. open a odt with form fields
2. fill the fields
3. export as pdf
4. try to convert the pdf to jpg with imagemagick

Actual Results:
In the jpg the filled forms are empty.

Expected Results:
The filled forms are also available in the jpg.

Reproducible: Always

User Profile Reset: No

Thank you for reporting the bug.
it seems you're using an old version of LibreOffice.
Could you please try to reproduce it with the latest version of LibreOffice
from https://www.libreoffice.org/download/libreoffice-fresh/ ?
I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' if the bug is still present in the latest version.

Thanks for the answer.
I tested with the latest version and it still does not work.

I did

convert -colorspace CMYK -alpha off -interlace none -density 300x300 -quality 100 formfield-fdf.pdf formfield-fdf.jpg

after filling the form in Okular and saving and the jpg contains the text.

Justin: do you really get an empty field, if you test with my PDF? I also tried exporting with PDF format forms, but that worked fine as well.

Sorry for the delay.
Yes I tested again and also with the test files I do not get the filled form. I also tried with your command. Still the same.

My actual command was like this:
convert -density 200 -background 'white' formfield.pdf -alpha 'remove' -quality 85 -verbose -version formfield.jpg
Comment 7 Buovjaga 2018-07-24 08:16:45 UTC
Eh, my bad: contrary to your description, I filled the field in Okular and not LibreOffice. I reproduce, if I fill the field already in LibreOffice.

Dear Justin,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword
