Let not forget muPDF which renders also pretty fast on linux.

Yes, I am using Okular. Tried Firefox and FoxIt and they were instantanious.

Thanks for the tip Bill.

Re: [Therion] Water areas produce heavy PDF files

Hi Rodrigo -

What application are you using to view the PDFs?  I have found that Okular (and 
anything else based on the poppler libraries) is very slow to render any but 
the most basic maps.  Firefox running on the same machine will render the PDF 
far faster.  Adobe Reader is also much faster.  

I turned in a bug report on this to the poppler/Okular group last summer, and 
Albert Cis did some work on it.  He found a way to make it much faster.  I am 
not sure if that change has made it to the production version yet.  I have not 
seen it yet on my Fedora 35 system with poppler version 21.08.0 and Okular 
21.12.2.

I have not noticed that water in particular slows things down.  Maybe that is 
because every map I make has water in it!  :-)

[Therion] Water areas produce heavy PDF files

[Rodrigo Severo via Therion]

Hi,

Does anybody knows why water areas result in such CPU intensive PDFs? And more 
importantly, does anybody have any idea on how to solve this?
