Hi!
When I insert any graphical PDF files in the document, LyX preview
(the program's editing window) shows them rasterized and in an
extremely bad resolution. In the 'pdflatex' PDF output everything is
ok, the quality is as in the original images.
I discovered that when I insert PDFs LyX converts them to .eps with
'pdftops'. I checked outside LyX and it works without any problems or
decrease in quality. When I insert those independently converted .eps
files (good-quality ones) into a LyX document I get the same results
as with original PDFs - rasterized and bad resolution.
I found some advice to set up EPS->PNG conversion with 'convert'
utility from ImageMagick because presumably LyX uses it to preview
EPS images. After I solved 'convert-im6.q16: not authorized' problem
(which somehow didn't affect LyX, only the command line) I indeed
found out that the default conversion line convert in.pdf out.png
gives a very low resolution PNG file. So I tried convert -density 300
in.pdf out.png fron the command line and it produces good quality
images. Then I inserted convert -density 300 $$i $$o into the LyX
EPS->PNG conversion line. And that changed absolutely nothing in the
LyX preview output, same low quality. Now I don't know what to do. It
seems this converter doesn't actually work in the program's window.
Could somebody help?
LyX 2.3.2, Ubuntu 18.04.2, XFCE 4.12
Try:
convert -density 200 -trim -quality 100 -sharpen 0x1.0 $$i $$o
you can try different numbers for 200

Please bottom-post. Start your reply here:
Maybe try adding --dpi=300 to the LyX Preview -> PNG converter line (and
possibly also LyX Preview -> PPM)?
