Water areas produce heavy PDF files
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? Regards, Rodrigo Severo
Hi, which symbol set are you using? Could you send some examples? Martin On Mon, Feb 21, 2022 at 7:46 PM Rodrigo Severo via Therion <therion@speleo.sk> wrote:

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! :-) ======== Bill Gee On Monday, February 21, 2022 12:36:43 PM CST Rodrigo Severo via Therion wrote:

Yes, I am using Okular. Tried Firefox and FoxIt and they were instantanious. Thanks for the tip Bill. Rodrigo
Take care which library use each viewer. PDF generated from Therion use group transparency knockout. Check wiki: https://therion.speleo.sk/wiki/contrib:externalviewers <https://therion.speleo.sk/wiki/contrib:externalviewers> I don’t know Okular, but only correct viewer is Acrobat. Martin S.

I agree that Adobe Reader defines what it means to be "compatible". However, for those of us running Linux Adobe Reader is not a viable option. I used to have an rpm file for a 32-bit Adobe Reader from about 2008 or 2010. Some library changes made it stop working. Okular and poppler are part of the KDE project. I found another application called Master PDF Editor which also renders Therion maps with reasonable speed. There is a free version and it is available for all of Windows, Linux and MacOS. https://code-industry.net/masterpdfeditor/[1] It is not as fast as Adobe Reader, but much faster than Okular. ======== Bill Gee On Wednesday, February 23, 2022 5:42:45 AM CST Martin Sluka via Therion wrote:

Let not forget muPDF which renders also pretty fast on linux. Am 2022-02-23 13:16, schrieb Bill Gee:
