Description the.heavenly.earth 2019-03-01 05:04:36 UTC
[1] The document looks Okay on LibreOffice (as designed); however, the fonts of hyperlinked texts look different, as they randomly change to unspecified type and/or color in exported PDF.  Even when the Preference setting was adjusted to use black color only to both visited and unvisited links.
[2] Also, there I noticed a sentence where it looked highlighted on LibreOffice, but not on the exported PDF.

Steps to Reproduce:
1. Write a document.
2. Create bookmarks.
3. Set the hyperlinks.
4. Export as PDF.
1. Write a text in purple.
2. Highlight a text.
2. Export as PDF.

Actual Results:
[1] Parts of Hyperlinked texts appear blue and in different font type in PDF, but looks black in the right font on LibreOffice.
[2] Highlighting function generally seems to work Okay for other highlighted texts, but there is only one highlighted sentence in a document, where the highlight does not show up in an exported PDF.  The text is purple #9B4FE7, and highlight color is "Light Yellow 3".  The text color shows correctly, but no highlight.

Expected Results:
[1&2] I would expect the PDF to appear in the same way as you see on the LibreOffice.

Reproducible: Always

User Profile Reset: No

Additional Info:
Thank you -- otherwise, It is a wonderful software.  I have used OpenOffice decades ago, but the software has significantly improved and stable.

Please provide a sample document we can use to try and reproduce.

Comment 5 Alex Thurgood 2019-03-14 09:10:46 UTC
I either don't understand what the problem is, or else I can't reproduce. When I take the supplied ODT file and open it in LOdev-master, I don't see any difference between the font colours of the ODT text and the resulting PDF obtained via direct export (PDF button from main toolbar as opposed to File > Export as PDF)).

Some of the highlighted text in the ODT is in purple (some with yellow highlighting and some without). These appear to be faithfully reproduced in the exported PDF.

In Preferences > Application Colours, for Visited/Unvisited links, I have the automatic default, although the boxes aren't ticked.

Sorry, no repro for me in master at least.

You might need to be more specific about which areas, links, of the document etc are misbehaving in your opinion or give further details on any configuration changes you might have made that could have an affect on the end result.

The ODT you supplied shows blue links (unvisited) for me with LO6152 and L0dev-master 6300, for example, in the Table of Contents. I have enclosed a comparative screenshot.

Please indicate which version of macOS you are using.
Also please indicate how you produced the PDF from LO:

- direct export (clicking on PDF button in main toolbar) ?
- export as PDF, and then choosing particular expport options ?
- if export to PDF with options, which boxes are ticked ?

> version of macOS:

macOS Mojave
Version 10.14.3

> how the PDF was produced from LO:

the results were the same however you produce the PDF.
- direct export (button)
- export as PDF
- export ..., then PDF selected

>- if export to PDF with options, which boxes are ticked ?

I was using the default setting first as in the fresh new install.  Similar problem persisted, so I decided to select all texts and unified the Font Type, Colour, and partly Size.

Then, I changed the Preferences setting > Application Colors > Unvisited links [Black] & Visited links [Black].

At least then, I could see all links in the same Black colour in LibreOffice but not when saved as a PDF.

Then, I tried different options for PDF, and the results were the same.
The final options for PDF selected (changed from the default) are shown on the following two attachments/screencaptures.

Comment 14 the.heavenly.earth 2019-03-15 15:06:04 UTC
Also, I remembered that not all hyperlinks showed underlines and/or appeared in Black, as I was writing in LO.  In some cases, I could not manually adjust the Font Colour or add the Underline.  In such a case, I deleted the text, re-typed the same text, and re-linked them to targets again.
Comment 15 Xisco Faulí 2019-03-21 10:05:34 UTC
You can configure how hyperlinks are displayed in LibreOffice from tools - Options - Application Color.

Could you please reset your Libreoffice profile ( https://wiki.documentfoundation.org/UserProfile ) and
Comment 16 the.heavenly.earth 2019-03-21 13:46:34 UTC
As I described in my comment provided at 2019-03-15 14:58:20 UTC, I have tried to set/fix the link color to black, to make them appear in the same color (instead of them showing up in different colors throughout the text).

I reseted the user profile, rechecked the hyperlink colors, and reproduced PDFs.  Nothing is changed -- I still see the mix color links in output PDFs.
Comment 17 Heiko Tietze 2019-04-15 14:18:08 UTC
Tried with both simplified example (some text and links) and your document. In all tests the visited link was blue whether or not visited. So maybe a macOS issue?

Nevertheless, visited links must not get this color when exporting to PDF. Clearly a bug to me.

Dear the.heavenly.earth,

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
