preload , prrender, precache full pdf setting?

Sun Oct 23, 2016 2:57 pm

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

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

Hi 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

Hi immo2014,

The best address to send it to is support@tracker-software.com.
and ofcourse all this advanced preload etc should be an option only so for people who dont want that dont use that
I'll speak with the Dev. Team to see if an option can be added, but please be aware that this will likely result in significantly longer opening & rendering times, especially for documents such as those you're working with.

Cheers,

Hi Will,

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.

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

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.

Regards,
Stefan

Hello,

The new version is out 6.0.319.0, is the feature implemented? I can't find it in settings.

Thanks

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.

Hello all,

just for the record, and for completeness of information:

The above probably is related to this thread's topic and findings:
Slow image loads since build 312

With respect to the "preload, prerender, precache full pdf setting" feature request by immo2014; +1 for this request from my side. There is a related discussion here:
Preload pages in PDF XChange Viewer

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.

Thanks for adding your voice here Timur,

It certainly can be a useful feature! As soon as we have any further news - we will post back here in the forums as well.

I agree that the lack of prerendering is particularly noticeable on this example file.

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.

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. :roll:

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.

Hi Guys,

We actually already have a FR ticket on this:
#2267: FR: Re: Preload pages in PDF XChange Editor
And I have just updated it with a link to this forum topic and brought it up higher up the queue so that it can be considered again!

Cheers,
Stefan

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.

Hello mikeylucky,

Thanks for adding your voice here.
The ticket is still open but I am afraid that there's still no estimate as to when this feature will be implemented.

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.

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.

hth

Paul
