There seems to be a licensing problem with htmldoc for windows installations ?

I did not manage to open pdf file, so I had to add a header line to download the pdf

Furthermore, htmldoc does not support unicode, I began a translation utf8 to latin1 for displaying french characters correctly , this may need enhancements.

SpecialPDF and MimeTeX
This is a really cool and useful extension. HOwever, it is ignoring an extension we added to support MimeTeX so that the output does not include any math created through that extension.

Our MimeTeX extension replaces Any LaTeX formula

Is there another way we should be generating this so that SpecialPDF can capture the image? DavidJameson 20:32, 4 August 2006 (UTC)

Updated for unicode, multiple articles, and images
Searched around for a way to do multiple articles to PDF, had to combine what was listed here and what was contained in wiki2pdf. Works the same way as SpecialPDF.php, put it in your extensions folder. HTML files are created (for processing) in your /webroot/wikiroot/pdfs folder (so create it if you don't have it) or another folder of your choice. It still uses HTMLDOC with some switches to format headers and footers, and there are string substitutions for the images exported out of the Wiki...

This doesn't work for me - I've added the php file to the extensions folder and altered Localsettings.php to include it. When I navigate to my site I just get a blank page rather than logon. I'm obviously missing something blindingly obvious.....


 * Windows XP
 * Apache 2
 * php 5.1.4
 * MySQL 4.1.16
 * Mediawiki 1.7.1

Forgot to add: Add a line to the bottom of your LocalSettings.php:

require_once("extensions/myPDF.php");

Bad argument to HTMLDOC
myPDF is not working for me. It's generating a bogus arg to HTMLDOC and so instead of getting a PDF file, I get a file with the error message:

HTMLDOC Version 1.8.27 Copyright 1997-2006 Easy Software Products, All Rights Reserved. This software is based in part on the work of the Independent JPEG Group.

ERROR: Bad option argument "--charse "!

Note that there should be a 't' at the end of the argument but instead there is an embedded CR control character

SCW, 05sept06, 10:09CT
A line break got into the cut and paste on that line for htmldoc passthru. take out the linebreak to join the lines together to make the argument to htmldoc '--charset' and all should be okay.

I'll be posting a newer version that has th option for creating PDF books with a title page, TOC and nice nesting of articles...

Simon.

No HTML files found
I must be missing something else....after fixing the linebreak problem, I opened a wikipage and then clicked on Export PDF book.

This time I got a file with the error:

HTMLDOC Version 1.8.27 Copyright 1997-2006 Easy Software Products, All Rights Reserved. This software is based in part on the work of the Independent JPEG Group.

ERROR: No HTML files!

Usage: htmldoc [options] filename1.html [ ... filenameN.html ] htmldoc filename.book

What's this notion about a "collection" of articles? Is there something I'm supposed to do to "collect" some articles together before I can print them? How would I do that, and why would I need to? The "Export PDF Book" link shows up in Toolbox when I'm viewing a particular page - So how can generate THAT page as PDF but including all images?

DavidJameson 15:36, 5 September 2006 (UTC)

okay, the following script is based of the original, temporary PDF files are saved to /tmp, like they were in the original. This script will not deal with putting multiple articles into one PDF file (see above for that). It will handle image files.

Almost there (grin)
Well, this version almost works perfectly - it gave me a nice PDF file with explicit images referenced in the wiki page.

However, it crashes when trying to handle one of the image tags produced by our MimeTex math generator.

E.g.

<img src="/cgi-bin/mimetex.cgi?\green f(\xi)=\int_{-\infty}^\xi e^{-\tau^2}d\tau { {x \atop y } }" align="absmiddle" border="0" alt="TeX Formula">

seems to cause a crash.

I wonder if the code that tweaks the IMG tag itself is getting confused with the more sophisticated stuff in this particular image reference.

PHP error
Just for grins, I ran the process through a PHP debugger. The debugger barfed with the error below. Error: E_ERROR Call to a member function getNamespace on a non-object at /var/www/html/wikiroot/riskit/includes/Article.php line 155

The line it's complaining about is			if ( $this->mTitle->getNamespace == NS_MEDIAWIKI ) { which is found in the function getContent in Article.php

(P.S.....someone needs to install the GESHI syntax highlighting extension on wikimedia.org)

DavidJameson 12:18, 6 September 2006 (UTC)

PHP error
OK - I've figured out both problems (to an acceptable extent)

1) The PHP bug is due to the fact that sometimes (and I don't know why it's only sometimes), the URL associated with the Print As PDF command in the toolbox has %0D%0A tacked on at the end. No idea where this is coming from but it can be removed by modifying the echo statement on line 103, adding a str_replace function to remove the extra characters. php echo htmlspecialchars( str_replace('%0D%0A', '', $monobook->data['nav_urls']['pdfprint']['href'] ))

2) The reason the math images weren't being processed was because the URL in the SRC attribute of the IMG tag did not include the server. I modified my mimetex extension to include the server but this problem will arise again for anyone else who references an image without using a server in the URL. The full solution will require the text to be searched for all image urls, examine them to see if there's a server part and if not, insert the $wgServer into the string. Probably can be done quickly with a regex. DavidJameson 20:31, 6 September 2006 (UTC)


 * What's wrong with just doing this: "$bhtml = str_replace ('/images/',$wgServer . '/images/', $bhtml);" instead of the $bhtml = str_replace ('/w/',$wgServer . '/w/', $bhtml); that you have there? Made the math images all work for me. --dgrant 18:30, 25 October 2006 (UTC)

No Images
Great extension, works really well except it doesn't appear to include images in the export. Can anyone please confirm that this is normal and that I haven't done anything wrong?

Thanks, CheShA.

Still No Images
Hi, can anyone tell me what to do that my PDF Exported File includes the Pictures from the Original article?

I´ve heard there´s a PDF Hack to fix that problem. If anyone had an idea,... please let me know

THX [mailto:DarkManX1@gmx.net X-Cident]

Still No Images
Hi there, someone can help us about this problem ? the PDF exporting is great, but the link is incorrect for the image "Image:Image_Name.gif", and the not the direct link itself.

Help please ! th3_gooroo@hotmail.com

Empty Files
Help, i only get empty files. But when i execute this line on the console i get a working pdf... htmldoc -t pdf14 --bodyfont Helvetica --no-links --linkstyle plain --footer c.1 --header c.1 --tocheader ... --charset 8859-1 --color --quiet --jpeg --webpage '$mytemp' > test.pdf Whats wrong ? Maybe an apache-issue or something ?


 * I had the same problem. I changed this line to  and it worked. The path before   is usually the same as   in LocalSettings.php.   is another usual path to try. --Ikiwaner 20:06, 20 December 2006 (UTC)

Clean code
Hi there, would be nice if you could post the clean code with all above corrections included. I tried them all with mediawiki 1.8.2 but I can't get it to work. Cheers Florian

Test and working on 1.9
this was tried on Linux/Apache/PHP5 with 1.9 in a software configuration very simillar to Wikipedia and works fine. tom

Working code for Windows with MediaWiki v1.9
The PDF export worked for me on Windows after I fixed the path AND more importantly on line 80, I had to change '$mytemp' to $mytemp - i.e. remove the single quotes aroung $mytemp.

Page rendering
Hello, I'd wish some improvement of this useful extension. While it works technically it's a fact that the pages look better when printed to a PDF printer over your web browser. To have an improvement compared to web broweser PDFs it should look more LaTeX-style. --Ikiwaner 00:00, 16 January 2007 (UTC)

Errors in the last version in discussion
Using the very last iteration of the code posted in the discussions, I get the following error when I click the Print as PDF link:

Fatal error: Call to a member function getNamespace on a non-object in /srv/www/htdocs/wiki/includes/Article.php on line 150

Working with sites starting with http://www...not with sites http://...
Seems to be working only with sites which include www in their adress. Is this possible?--87.2.110.219 21:53, 23 January 2007 (UTC)

A problem with htmldoc encoding
htmldoc is very sensitive about the encoding.

In file SpecialPdf.php, line 89 passthru("/usr/bin/htmldoc -t pdf14 --charset 8859-1 --color --quiet --jpeg --webpage..., for the new version of htmldoc --charset should be iso-8859-1 Ivan

What is the purpose of HTMLDOC, if it's Windows app?
Hi all

I don't quite understand, if HTMLDOC is a windows application, how will this help me if my web server is a Linux server?

A problem with PHP passthru
Thanks for the extension! I'm using MediaWiki 1.8.2 on Windows 2003 and it's work. I had a problem with the passthru fonction that i solved by copying cmd.exe in the php installation folder.

Where do I download extension
Can't seem to find SpecialPage.php, where do I download the file?


 * Just cut and paste the code above into a text file with that name and extension. Jschroe

Scaling Images to fit paper width
I found an argument to htmldoc, that allows you to specify the 'width' of the page in pixels, which is sort of the opposite of scaling, but rather, setting the viewable resolution for the images. So, I have an image that is 900 pixels wide, I'd want to set my browser width to something greater than 900 to see the whole image at once. passthru("htmldoc -t pdf14 --charset iso-8859-1 --color --quiet --jpeg --webpage '$mytemp'"); would become: passthru("htmldoc -t pdf14 --browserwidth 950 --charset iso-8859-1 --color --quiet --jpeg --webpage '$mytemp'"); --DavidSeymore 18:48, 14 May 2007 (UTC)

Title of Wiki-Article in PDF
Hi,

i was wondering if it it possible to display the title of the Wiki article in the generated PDF?!THX

Name of the generated file
The extension works fine except for the fact that is outputs a file called index.php, renaming this to something.pdf works as it is in fact an pdf file. But I m wondering how I could fix it so it outputs <article_name.pdf>. Any suggestions?

Solution
I needed to uncomment this line to get <article_name.pdf> instead of <index.php>.
 * 1) header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $page));
