About giving feedback

Please read Reading/Web/PDF Functionality and comment on the plans we lay out there, to tell us what you need from the PDF service. We're especially interested in what you need in the future that doesn't exist in the plans laid out there – if there's a bug with something that should work right now (e.g. you get an error message when you try to create a PDF), we need to fix it, of course, but that would have been on the agenda.

Update: (23 April 2018) PediaPress will take over the development of the books-to-PDF functionality. See Reading/Web/PDF Functionality for more information.

Updates: (24 February 2018)

- Kerning and spacing issues (https://phabricator.wikimedia.org/T178665): there has been a few reports on spacing issues within PDF rendering. The readers web team is currently looking into a solution. We will first be updating the fonts for PDFs (https://phabricator.wikimedia.org/T181200) over the week of November 27. This will resolve some but not all of the spacing issues. We'll be looking further into the remaining issues after the initial fix.

unicode of futhark runes not displaying

I noticed when downloading a pdf of the "Elder Futhark" page that when the runes are in Unicode they don't display at all. They appear as blank boxes instead.

Noted. Thank you for reporting, it's much appreciated.

mediawiki2latex can handle the article inculding the runes

It is now nearly three months since the last update and test document. Would it be possible for PediaPress to give us a progress report?

Johan (WMF) (talkcontribs)

PediaPress has been working on some LaTeX stuff lately. @Ckepper, is there anything else to report?

Ckepper (talkcontribs)

As Johan reported, I have been quite busy with other stuff (like paid work). The last thing I worked on was LaTeX support (See Maxwell's Equations and Schrödinger equation). This had some detrimental effects on image scaling - see pages 11 and 15 in the Schrödinger article - that I have not yet been able to fix. Moreover, it seems like some formulas are not rendered correctly at all: check out the Formulation in SI units convention for an example - the scaling of the formula seems completely broken and I am lacking the LaTeX skills to fix this. This could be a problem wit my local LaTeX distribution, or local settings or within the LaTeX formula itself. Any insight into how this could be fixed would be highly appreciated.

The last big piece that I haven't touched at all are tables. With the original PediaPress renderer, this was the most complex part but maybe we can start small and expand the feature-set. I would rather focus on setting up a basic render server so people can start using it.

PediaPress created a LaTeX renderer 10 years ago that is still in use today. The biggest challenge we faced with rendering Wikipedia was the heterogeneity of the content. Most editors stop working on an article when it looks as intended in their browser. Semantic or "clean" markup are not of particular interest. You can fix this for a small number of pages (or extensions) but it becomes unsurmountable when you want to address all of Wikipedia.

We decided to use a HTML / CSS Paged Media based renderer because this approach creates the least amount of friction between on-screen and print content for the majority of the pages. Other projects and more qualified engineers might find better solutions but I will continue on the current path.

Another problem is that mediawiki2latex is written in a language called haskell, which not many programmers know. It would be difficult to ensure flexible support options in the future, which is the very problem which brought us to today's sorry state.

Dirk Hünniger (talkcontribs)

Hi,

I am the developer of mediawiki2latex. I currently work on a paid project for the German government, so my time is quite limited. It is even hard for me to take part in my Aikido classes.

I will try to keep the mediawiki2latex website up and running as well as maintain the mediawiki2latex Debian package for as long as I can. But I currently don't have any time to add new features and it is unlikely that I every will. A similar project also written in Haskell is called pandoc. Its very actively developed. But still I think you currently do get better results with mediawiki2latex.

I also recommend to learn Haskell. Probably you will not use it at work, but the skills you learn by doing Haskell are very helpful in day to day work as software developer or scientist. It a bit like studying maths at university. You will never need to work with these abstract objects as such, but the skills to solve problems in abstract manner are really handy.

Yours Dirk

The PDF links seem to be completely broken. Every attempt I've made at downloading a PDF has only caused the page to hang indefinitely.

It's extremely crucial that someone find a way to resolve this issue. Wikisource is a lone beacon of hope for people who need access to public domain literature, as search engines are becoming increasingly congested with links to malicious sites that won't surrender downloads unless you're willing to allow your computer to be infected with spyware.

Johan (WMF) (talkcontribs)

We haven't seen this on our side, but are investigating. Thank you for reporting.

Johan (WMF) (talkcontribs)

Could you tell me what articles you've been trying to make a PDF out of?

Slow Download Response - Again/Still

Once again the pdf download function sometimes hangs, times out, or takes double-digit minutes to respond..

I have pointed this out (complained, really) several times and it is beyond me why you cannot fix this once and for all. Gazillions of websites have download-as-pdf and they work fine every time.

As I said in my last "complaint" you are not getting single penny from me at donation time unless this is fixed once and for all and that incredibly embarrassing months-old "We have technical problems with the function we use to create PDFs. We unfortunately have to replace it." message is gone because it is no longer needed.

Johan (WMF) (talkcontribs)

Wikipedia combines being one of the most visited websites in the world with being run without profit and refusing to sell ads. This is important, and we wouldn't be the same if it weren't true, but we never quite have the developer time and resources we'd like to have. There are more things that don't work as one would expect on one of the world's largest websites – it's more difficult to develop things for Wikipedia, because of the amount of traffic a function has to endure.

(Nothing is ever fixed once and for all. Entropy gets us all in the end. Code has to be fixed, then redone, as time passes.)

Johan (WMF) (talkcontribs)

Nevertheless, we hope these problems are caused by the current renderer, which we hopefully will replace in a couple of weeks. We'd be grateful if you could keep an eye out for that announcement and tell us if it hasn't fixed the problems for you.

Also, could you tell me what articles you've been trying to make PDFs out of?

And what type connection you've been using to access the internet?

the pdf form is not available.so please remove the option or otherwise it should work...

InsaneHacker (talkcontribs)

The option to create PDF renders is available, it just has a lot of issues that are being worked out, and the banner on the "create PDF" page says as much.

Steelpillow (talkcontribs)

The article PDF output is available, the book PDF output is not. Hope this helps. Steelpillow (talk) 19:43, 12 October 2018 (UTC)

The font on several subjects when downloaded to a PDF is so small its barely readable.

Johan (WMF) (talkcontribs)

Thank you for the feedback. Could you give specific examples?

Book printing function of August 8th

Salino01 (talkcontribs)

It is very nice to get a new feedback about the book function. The example already looks quite good. Here are some comments about Amphibious aircrafts.pdf from 08/17/2018:

1. the image size is too small for printing as a book (probably about 15x20cm book size). In the past, images took up the entire page width or half the page height and are therefore better suited for illustration.

2. the font size also seemed too small to me.

3. the link to Wikimedia Commons is too prominent.

4. the links are missing in the references. Without them, many references are useless. This applies in particular to the section "External links".

5. the articles are grouped in the preview. This results in "Article 5 of 4" in the footer on page 36.

BluAlien (talkcontribs)

Yes I agree and also text align is quite a little messy. The text should be justified. Also the document format in 2 columns, left text and right images is very boring, cold.

Johan (WMF) (talkcontribs)

Thanks.

You need to be more specific, what "topic" do you need to download, and from where?

Johan (WMF) (talkcontribs)

Hi @Ascjames, where did you previously save the book?

Ascjames (talkcontribs)

Thanks Johan -

I saved the book in Wikipedia. I also, fortunately, downloaded most of the pages to this computer.

Sometimes, but not always, there is a banner near the top of the page that asks "add this page to your book?" I add the page and the counter rises by one to show how many pages are in my book, In this case, the book, titled something like "FRENETTER - (a tale of Mississippi), disappeared after I added 10 or more pages.. I saved it here in Wikipedia. I saved and had a similar titled book a few years ago. This one is new..

Steelpillow (talkcontribs)

do you have a link or the page name you can give? We need to know which book we are looking for. Steelpillow (talk) 11:12, 17 October 2018 (UTC)

I am finding it hard to find any record. Without the exact page name I cannot check if it has been deleted. Also, there has never been a user called Ascjames on the English Wikipedia. Do you have another user name there, or are you editing a different language Wikipedia? Steelpillow (talk) 19:40, 18 October 2018 (UTC)

Ascjames (talkcontribs)

Hello Steelpillow.

I'm going to try harder to find the name I used before.

Thanks for your care.

James

Steelpillow (talkcontribs)

If you can tell us which language Wikipedia it was and what your user name there is, we can search for it and someone may be able to retrieve it. Steelpillow (talk) 08:48, 26 October 2018 (UTC)

Ascjames (talkcontribs)

Thank you. I think I have saved all the articles elsewhere.

Let's stop searching, for now. I don't remember which name I signed in under.

I've started a new book under Ascjames.

Your work is greatly app-reciated by me.

James
