preload , prrender, precache full pdf setting?
When I read a magazine on my screen I expect instant switching pages else its very unpleasant to read.
How can I when I open a magazine/newspaper pdf with about max 150 pages make it preload, prerneder, cache all pages so after all its done I have instant switching times
my specs are I am on a 2560x1440 display with 96gb ram and 16(32) cores

Re: preload , prrender, precache full pdf setting?
Hello immo2014,
Is the file you are trying to open a download version of the magazine, or one that is prepared to go to printing?
I presume it's the latter option - as on your machine only print ready files should show any delay in rendering.
Unfortunately there is no such option to "prerender all" pages of the file, as this could cause quite some troubles for most users and with very long files (you never know when you could get a 2000 page specification e-mailed to you, - which while e.g. a few MB as file size could generate gigabytes of temp files if we try to render all the pages and store them).
How long is the transition time for you? If there are any files that you can share - can you please do so with even a few page document, so that we can run some tests on it?
Regards,
Stefan

pls give me a mail so I can send you a sample PDF magazine/newspaper. Its for reading and some pages take 20s to render
flip times are to high and by far not instant
and ofcourse all this advanced preload etc should be an option only so for people who dont want that dont use that

as most modern PC has 8+ logical cores (mine has 32) it makes sense to render the pages in background so when you open a magazine pdf and you check the first page about content it should start in background to render/precache the following pages
I sent you 2 sample magazines and you can see that reading these with xpdf ist not real fun.

Re: preload , prrender, precache full pdf setting?
Hello immo2014,
I passed your files to a colleague from the dev team, and he asked me to make a ticket in our internal system for those:
#3714: Editor 318.1: Slow rendering of page with more than 3000 images
Page 12 of the 20161024-Handelsblatt.pdf file has 3000+ images on it, so we need to see how to improve the rendering speed for that, as our (older and no longer developed) Viewer handles that page much faster.
As for the pre-rendering of following pages - I will bring it up on the next meeting and see where we stand for such a feature.
Regards,
Stefan

Re: preload , prrender, precache full pdf setting?
Please add precache next page, it's a pain to wait 0.5s each page to view the page. i'm returning to adobe reader, at least abode reader precache the next few pages, so no wait for turning page.

Hello mozillafi,
I didn't create a ticket for this, as it's already being considered. We will add such a preloading as soon as technically possible! Though it will likely be off by default and will have to be turned on from the preferences window.

Hi mozillafi,
It doesn't appear that this has been added yet. I can't confirm the build that the Devs. plan to implement this just yet, but hopefully within the next build or two.

Re: preload , prrender, precache full pdf setting?
What are the current plans on developing the prerender feature? I'd like to have it since the file https://archive.org/download/manysidedf ... rduoft.pdf renders quite slow (2 seconds per page), which is uncomfortable when prooflistening an audio recording in real-time.

Count me in on wanting this feature. Caching a whole file is impractical, but pre-rendering one or more following pages makes a lot of sense.

Re: preload, prerender, precache full pdf setting?
I agree that the lack of prerendering is particularly noticeable on this example file.rillig wrote:What are the current plans on developing the prerender feature?

For some reason, I actually thought that PDF-XChange Editor did already prerender one page ahead (and one page back) from the current page. But as can be seen from that scanned book linked by @rillig, this is not the case.
Strangely, not even PDF-XChange Viewer (v2.5 build 320) seems to pre-render one page ahead (anymore?), other than stated here by Paul.

Re: preload , prrender, precache full pdf setting?
I remember that in the past I did some tests with various PDF readers to find out whether they pre-render or not. But I cannot remember the results anymore.
Acrobat Reader DC seems to pre-render. I am not sure how many pages, but it seems like it pre-renders 6 or 7 pages in advance. This may be connected to how fast you flip pages (or how long you stay on one to read). Editor doesn't even seem to pre-render pages when continuous mode is used and part of the next page is already visible.

Re: preload , prrender, precache full pdf setting?
I sincerely wish PDF-XChange Editor could automatic preload of the next 6~10 pages.
otherwise currently its performance is really bad if I fast scroll the pages with a lot of pictures in it.

Re: preload , prrender, precache full pdf setting?
Hello,
I do not know if it can help someone, and how strictly PDF-XChange Editor is making a difference between "large" images and let's say "normal" images, but in times where PC's were not yet as performant as they do now, an option was (and still is) available for "Display large images", yes or no.
If the (large) pictures in the PDF are less important for the reader than the text itself, people can still consider to turn OFF the display of large images, via the Edit-menu > Preferences > Page Display. Take care, this is a general application setting, not a "per document" setting.
Best regards.
N.B.: myself I did not succeed to NOT display images in PDFs after un-check of the indicated option.
I do not know how PDF-XChange Editor exactly works, calculates or makes its decision for this.

Re: preload , prrender, precache full pdf setting?
Hi guys,
I touched base with the Editor development team leader today regards this. I can confirm that some of the required work has been done, however the priority on this has not, to date, been set as high. We will likely discuss this in a meeting this week. That priority may be raised, but as of right now I cannot make any promises.
We should have something more concrete later in the week.

Re: preload , prrender, precache full pdf setting?
More like several years. What you can do is to manually increase the cache size of Editor and then keep the right arrow pressed on your keyboard. This will (pre)render all pages into the cache. Unfortunately this cache is not saved to disk, not even as an option, so you have to do it all over again once you close Editor.
Re: preload , prrender, precache full pdf setting?
Yes, it's still a pain to do so... I just don't understand why it's that difficult to put an option for that...

Re: preload , prrender, precache full pdf setting?
A few more years have passed, just wondering if version 10 is likely to get preloading?
I was thinking about updating my maintenance plan for the next couple of years (PDF-XChange Editor already does everything I need!) so I'm only really interested in quicker viewing with pre-rendered pages

At this moment, I cant really give a solid affirmation for or against it. We are working on it, but it is one of those "when it is ready" items, that could take a very long time to complete.

Re: preload , prrender, precache full pdf setting?
Hello, Timur Born
I am afraid pre-rendering is not a priority at this time. We have improved our overall rendering speeds to the point where such complex changes would be negligible unless the file is notably overcomplicated (which is both a fairly rare case, and if an entire document is that complex, trying to pre-render all pages would lead to other delays in functionality until it is complete).
When our small dev team has the time to dedicate to a large project like this, we may see some change, until then, our focus is on other items that have more notable impact on the applications more common uses.
Kind regards,

Hello, Timur Born
Yes, preloading one or two pages ahead would negate a few of the use case complications, but it would still be just as complex on our end to implement, and the situations where these issues appear is still infrequent.
My previous example however, was specifically considering the title of this thread (being "[...]full document"), so I was imagining a case where you have a file with 10-500 pages, and nearly all of those pages are complex enough that you see some notable delay on each page when scrolling through the file normally.
As before, this is still in a "it will be here, when it is ready" state. It ha not been expressly rejected, it is just not as high priority as many other tasks.

Re: preload , prrender, precache full pdf setting?
A full document pre-rendering - or rather background rendering after opening - would have its uses for sure. Like faster initial searches.
Personally I am still a big friend of having a prerender cache file on disk/SSD, similar to GPU shader caches of games. Some PDF files *never* change, so rendering it once only would make sense. But I already got the counter-argument of not wanting to waste (cheap) disk-space even if it would improve (expensive) CPU processing times. At this point we know that neither the background rendering nor the caching will happen.

Hello Timur Born,
Not for now, though it is a feature we are considering!
Kind regards,

Thanks. This surprises me. In the past there has always been the determined stance that this would waste user HDD/SDD space!?
