1 Reasons to Abandon Feature

The ILIAS Test currently uses wkhtmltopdf as its PDF renderer. However this has several flaws:

it relies on a command line tool, which needs to be installed
wkhtml is not very well maintained, see https://wkhtmltopdf.org/status.html
it comes with security risks, also see https://wkhtmltopdf.org/status.html

Also, the User-generated PDF Files lack some information, e.g. the title of the Test and the generation is prone to errors. The print view is sufficient. This article only tackles the PDF Export for Users. The Test archive file is not the subject of this article.

5 Discussion

Use the following discussion section to express your objections against this request or your consent to get rid of this feature.

JourFixe, ILIAS [jourfixe], 27 JUN 2022 : We highly appreciate this suggestion and abandon the generation of PDFs by the user with ILIAS 9. Please check if the button "Print" or "Print View" is appropriate for the different screens (if a print view is opened, "Print View" is correct).

Strassner, Denis [dstrassner], 15 AUG 2022: I forgot to add the link to the excellent post at the Administration - Installation - Core Forum by Tesche, Uwe [utesche]. To clarify once again where the PDF export is abandoned everywhere, here is the list of places:

<Test> >> Questions >> Print View >> "PDF Export"
<Test> >> Questions >> Review >> "PDF Export"
<Test> >> Results >> All Participants >> (Participant-Action-Menue:) "Test Results" >> "PDF Export"
<Test> >> Results >> All Participants >> (Participant-Action-Menue:) Test Results >> "Detailed Results" >> "PDF Export"
<Test> >> Results >> Test Results >> "PDF Export"
<Test> >> Results >> Test Results >> Detailed Results >> "PDF Export"
<Test> >> Info >> "Start New Test Pass" >> "Finish the Test" >> "PDF Export" (you have to be activate the options: "Exam View" and "Overview of Answers Given" and "PDF Download" to get the button)
