I think that the problem here is that even when the imported graphics is *.svg file or a *.pdf file generate from a *.svg file (e.g., using Inkscape) -- and hence definitely is vector graphics, the preview in LyX often looks blurred when the LyX preview is scaled up to be visible on high resolution screens.
As an example, the following drawing has been made in Inkscape as purely vector graphics drawing (*.svg, saved as *.pdf at 300 dpi). When scaling it to 200% in LyX, it starts to look muddled – LaTeX math which is produced as vector graphics starts to look unreadable on screen: [cid:[email protected]] Maybe this helps if I save the pdf file at a higher resolution? I.e., maybe Inkscape converts the drawing to bitmapped PDF? I would have loved to import the file as a *.svg file, but the LyX previewer and PDF generator sometimes messes up the arrows :-( . -B -----Original Message----- From: [email protected] <[email protected]> On Behalf Of Kornel Benko Sent: mandag 12. november 2018 13.39 To: [email protected] Subject: Re: PDF graphics is blurred in LyX when scaled Am Montag, 12.
