Bug ID: 118616
Summary: PDF export of a form's scrollable memo field shows
fewer lines than on the original form
Product: LibreOffice
Version: 6.0.5.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: minor
Priority: medium
Component: Printing and PDF export
Assignee: libreoffice-***@lists.freedesktop.org
Reporter: ***@gmail.com

Created attachment 143384
--> https://bugs.documentfoundation.org/attachment.cgi?id=143384&action=edit
To demonstrate PDF shows fewer memo lines than on original

When a form showing a scrollable memo field containing more lines than the
field can display is exported as a PDF file with "Create PDF form" checked, the
field on the resultant PDF file shows a scrollable field containing fewer
visible lines than in the field on the database form, though the hidden lines
may be viewed by scrolling. I suspect a font problem in that the font used in
the PDF file is different from (and slightly larger than) the default font used
in the database form field.

To demonstrate :-
1. Open the attached "Test7 - Memo.odb" database file.
2. Open form "Form1" - this will display a form containing a field of type
memo containing 10 lines, of which the first 7 lines are visible, with a
scrollbar allowing the remaining 3 lines to be viewed.
3. From the menu bar, select "File", then "Export as PDF..."
4. On the right hand side of the resultant "PDF Options" panel, check only
"Create PDF Form" and "View PDF after export", then select "Export"
5. Save the resultant PDF file to a convenient place - it will then be
automatically displayed.
6. Observe that the scrollable field on the PDF file displays 5 visible
lines, not 7, and they appear to be preceded by a blank half-line. Using the
scrollbar, it is possible to view the remaining 5 lines, and they appear to be
followed by a blank half-line.

I suspect that it may be relevant that my screen resolution is 1440 x 900.

Hello,
Thanks for reporting the issue.
I see different behaviours depending on the PDF Viewer.
Which one are you using?

I have set the bug's status to 'NEEDINFO'. Please change it back to
'UNCONFIRMED' once the question has been answered

You are right Xisco Faulí - behaviour is very dependent on the PDF viewer used.

If I open the PDF file with my default PDF viewer of Adobe Acrobat Reader DC
(build 2018.011.20058), behaviour is as described in the original bug report,
ie. 5 out of 10 lines are visible in the panel, rather than 7 out of 10 as on
the original ODB document form. Unlike on the original ODB document form, there
is no vertical scrollbar to indicate that there are further (hidden) lines. If
I click in the panel, a vertical scrollbar appears and the remaining 5 lines
may be viewed either by using the scrollbar, or by repeatedly selecting
cursor-down.

If I open the PDF file with Microsoft Internet Explorer 11 (build
11.228.17134.0), it shows apparently identical behaviour .

However, if I open the PDF file with Google Chrome (build 68.0.3440.106), 8 out
of 10 lines are visible in the panel. There is no vertical scrollbar to
indicate that there are further (hidden) lines. If I click in the panel, no
vertical scrollbar appears, but the remaining 2 lines may be viewed by
repeatedly selecting cursor-down.

If I open the PDF file with Microsoft Edge (build 42.17134.1.0), 7 out of 10
lines are visible in the panel. There is no vertical scrollbar to indicate that
there are further (hidden) lines. If I click in the panel, no vertical
scrollbar appears, but the remaining 3 lines may be viewed by repeatedly
selecting cursor-down.

If I try to open the PDF file with LibreOffice Write or LibreOffice Impress, it
actually opens the file with LibreOffice Draw and seems to convert it to an ODF
Drawing (.odg) file before displaying. In this case, all 10 lines are displayed
(with no vertical scrollbar), but only the first 9 are within the panel and the
remaining line is below the panel.

If I try to open the PDF file with Microsoft Word 2016, it attempts to convert
it to an editable Word document before displaying, but fails miserably. The
panel is displayed, but is empty.

None of the PDF viewers that I have tried exactly replicates the original ODB
document form, but it appears at first that Microsoft Edge is the closest in
behaviour.

Version|6.0.5.2 release |Inherited From OOo

--- Comment #5 from Alan Wheeler <***@gmail.com> ---
Tested with LibreOffice 3.3.0.
Similar symptoms to those described in the original bug report are exhibited
using 3.3.0, so set version to "Inherited from OOo"
