Requirements determine which application is appropriate and which application is not. Therefore, we must first clarify our needs:
1) Bookmark: We hope that the PDF software has a bookmark function, which is equivalent to displaying a book catalog
2) Mark: Can add annotation function, take notes while reading for future reference;
Matters needing attention, before using PDF software, we need to pay attention to the following issues:
1) Bookmarks and the Outline in a PDF
Evince, a document viewer for multiple document formats（排除）
Official address: https://wiki.gnome.org/Apps/Evince
Add annotations: Evince / Adding annotations
Use bookmarks: Evince / Bookmarks
View bookmarks: Where are evince bookmarks stored?-Ask Ubuntu
We currently use Evince 3.30.2 version
Disadvantages and problems
1) The marking function has limitations: you cannot mark pictures (because some of our PDF documents are scanned pictures)
2) Cannot add notes normally: adding Note text cannot be saved directly (save as needed), and the following error will be generated:
* (evince:24914): WARNING **: 11:25:08.048: Unimplemented annotation: POPPLER_ANNOT_LINE. It is a known issue and it might be implemented in the future.
Okular, a universal document viewer (excluded)
Official address: http://okular.kde.org
We have currently used Okular Version 1.3.2
Disadvantages and problems
1) After adding inline note, Chinese cannot be displayed
Some buttons in the sidebar have no icons
Bug #1698656 “navigation panel icons missing on standard install...”
Some buttons in the sidebar have no icons, as shown in the figure , follow the steps below (GNOME Shell 3.30.2):
# apt install systemsettings kde-config-gtk-style kde-config-gtk-style-preview oxygen-icon-theme 1）Then, run systemsettings5, 2）click on Application Style, 3）select Oxygen as a Fallback theme, 4）click on Apply. 5) Then restart okular;
xpdf, a free PDF viewer and toolkit（排除）
Official address: https://www.xpdfreader.com/
Disadvantages and problems
1) Poor user interface interaction
Foxit Reader, Industry’s Most Powerful PDF Reader
Official address: https://www.foxitsoftware.com/pdf-reader
We currently use Foxit Reader version 2.4.4.0911
Disadvantages and problems
1) In GNOME Shell 3.30.2, after hibernation, when the computer is turned on again, the window cannot be displayed, but the process is still;
# 09/15/2020 This problem will occur in a multi-monitor scenario. For the external monitor of the notebook, open the Foxit Reader software, after get off work, close the notebook, and unplug the external monitor. Open the notebook again after going home, the Foxit Reader window is no longer displayed, but the process still exists. # 09/17/2020 If you don't have an external monitor, just use the notebook, you can turn on the notebook again after a while without any problems.
