Bug ID: 416659 Summary: Okular PDF line rendering worse than in other PDF viewers Product: okular Version: 1.6.3 Platform: openSUSE RPMs OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: PDF backend Assignee: okular-de...@kde.org Reporter: tommi.niemi...@legisign.org Target Milestone: --- Created attachment 125344 --> https://bugs.kde.org/attachment.cgi?id=125344&action=edit Sample PDF drawing in Okular vs muPDF SUMMARY Okular tends to have trouble rendering line drawings exactly in PDF files. This is especially noticeable in varying line widths or the spacing of dots in dotted lines (as shown in the attached sample screenshot). STEPS TO REPRODUCE 1. Produce a PDF file with a line drawing. 2. Compare line widths in Okular and another PDF viewer such as Zathura or muPDF. OBSERVED RESULT In Okular, line widths vary without any apparent pattern. muPDF and Zathura produce top-quality results. EXPECTED RESULT Line widths should follow whatever is in the PDF file. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Leap 15.1 KDE Plasma Version: 5.12.8 KDE Frameworks Version: 5.55.0 Qt Version: 5.9.7 ADDITIONAL INFORMATION The attached image shows how different line widths appear in Okular vs. in muPDF, which (despite the 96 dpi rendering) produces uniform line widths. -- You are receiving this mail because: You are watching all bug changes.
