I'm including some figures in a lyx and I would like to have a preview
with better resolution. I'm using a lyx file as a logbook and I would
like to see clearly pictures and included documents.
Picture scaling increase the dimension but not the resolution.
I tried to add a new converter in Tools-File-handling-Converters from
PDF to png but it didn't work.
Only solution seems to be to put the picture inside a preview box.
Another problem is when including external material with pdfpages. If
you specify for example in the latex options "pages=4" in the preview
you see always the first page. In this case if you include the pdfpages
inside a preview box you get an error message on output Warning: Failed
to produce 1 preview snippet(s).
Please could you give me some suggestion?
