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.....

Hello Editing the Page

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

DavidJameson 14:22, 5 September 2006 (UTC)

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.

DavidJameson 12:10, 6 September 2006 (UTC)

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

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)

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? There is also a Linux Version!

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

Change $html = "  ". $page. "  " . $bhtml. " ";   to something like $html = "    <H1>". $title. "</H1>". $bhtml. " ";  Suspect

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));

Generated PDF is 1kb and corrupted
I am testing MW 1.10.1 on a LAMP system (upgraded from 1.6.7). Then tried the instructions on the main article page. After clicking on the Print to PDF link though I get a 1kb PDF. Any ideas as to what could be wrong? How do i go about fixing this? SellFone 07:23, 3 August 2007 (UTC)

Solution
I downloaded the HTMLDOC Binary and i didnt realize that you had to pay for it. When I ran it, it asked for a license and so I went ahead and installed gcc & gcc-c++ so i could compile from source and now its working.

Patch to Export Multiple Pages to PDF

Has anyone a solution,, to get this run under windows ?
Please post here. Export works already fine, but the pdf file is empty.

 * The code as posted above under Working Code for Windows with MediaWiki v1.9 works.. you just need to make sure the temp file path exists and is writable, and that IIS anonymous user has access to cmd and anonymous access is possible for images.. Suspect

To fix this problem, replace parent::__construct( 'PdfPrint' );

with SpecialPage::SpecialPage ('PdfPrint');

Got it working on Win2k3 and MediaWiki 1.10.1 (Finally)
Here's the solution. Copy and paste the code from above, and make the following modifications:


 * Download the latest version of HTMLDoc (which, despite the claim that it has an installer, it does not)
 * Extract the contents of the HTMLDoc zip file to C:\Program Files\HTMLDoc\
 * Add "C:\Program Files\HTMLDoc\" to the PATH environment variable
 * Set IUSR_<MACHINE-NAME> "Read" and "Read & Execute" permissions on C:\Windows\System32\cmd.exe
 * Set IUSR_<MACHINE-NAME> "Full Control" on C:\Windows\Temp\
 * Copy and paste the new PdfExport.php code from Working Code for Windows with MediaWiki v1.9
 * Change the value of $mytemp to $mytemp = "C:\\Windows\\Temp\\f" .time. "-" .rand . ".html";

That was enough to do it for me - hope this helps some of you!

~JT

Got it working with Win2k3 and MediaWiki 1.11.0
~Mark E.
 * I used the above instructions for 1.10, except the value of $mytemp indicated by JT was wrong - I have changed it to include double backslashes.
 * If it still doesn't work, try copying your CMD.exe to your \PHP folder. Make sure your PHP folder has IUSR_MACHINENAME read and read & execute permissions.

More robust way of ensuring URL's are absolute
I've had to make URL's absolute for a couple of other extensions and found a more robust way than doing a replacement on the parsed text. Instead just set the following three globals before the parser is called and it will make them all absolute for you: --Nad 04:00, 5 September 2007 (UTC)

Nad, Is the parser that you refer to already in the php script that is on the front page? I've added those lines at the top of the file, after $wgHooks and before function wfSpecialPdf, and still no images?
 * I also tried putting those lines in SpecialPdf.execute after $wgServer; and before  $page = isset( $par ) ? $par : $wgRequest->getText( 'page' ); Still no joy. Datakid 01:31, 6 September 2007 (UTC)
 * Ideally they should be defined just before the $wgParser->parse is called in the execute function. But I've just grep'd the html output of one of my exported PDF's from Extension:Pdf Book which uses this method of "absoluterising", but it hasn't worked for the images, maybe best to stick with the current text-replacement until I sort out that problem. The replacement used to make the url's absolute is:


 * Just realised that you also need to modify $wgUploadPath to make image src attributes absolute too, but I also have a problem with images showing up even with the src attributes being absolute... --Nad 04:13, 6 September 2007 (UTC)

Newest development is to allow an arbitrary number of such repositories per installation. Since it is likely for them to have different individual algorithms to 'absolutize' their path names, it might be a good idea to rely on an image-related function for the task. Images 'know' which repository they are in, including the local file system, or the upload directory. The philosophy of image related code is to always address Image objects, and usually not deal with repositories directly. So when you find an image in the source text, get a  object, and you probably have a function returning an absolute URL right with it. If it's not there, add it, or file a bug. If you cannot do it yourself, you could also ask me to add it, and I might even do so (-; I'm dealing with image-related functions anyways atm. ;-)
 * Holla,
 * Keep in mind that,  above is highly installation dependant, and may be quite different between installations, actually, it can be any string from   upwards.
 * Keep in mind that, not every image resides in the $wgUploadPath or a subdirectory thereof. Images might be in a shared repository, like WikiMedia Commons.
 * --Purodha Blissenbach 07:55, 8 September 2007 (UTC)


 * Having had a glace at the code, I am pretty certain that, the structurally correct way is, to let the parser object take care of asking image objects for absolute URLs. That means, add a  or similar, which is likely not yet possible, but imho pretty easily added to the parser. Investigate! It may be already there. Else, see above.

Bug: /tmp/ not writeable due to openbasedir restriction.
We did not get a pdf file, but got a series of php output of the type:

instead. We suggest, not to send these downstream (with wrong http headers, btw.) but rather display a decent error message on the special page. Likely, using  before writing into the file would do. --Purodha Blissenbach 16:48, 8 September 2007 (UTC)

Bug and Fix: Pdf Export blocks Semantic MediaWiki
We have several extensions installed, and included Pdf Export before including SemanticMediaWiki (SMW). The outcome was SMW not working: Thus the installation of SMW could not be completed. It requires the Special:SMWAdmin page to be accessed.
 * Special:Version looked as expected, but
 * Special:Specialpages did not show any of SMWs special pages,
 * URL-calling the page Special:SMWAdmin, or entering it via the seach box, yielded a "nonexisting special page" error.

Pdf Export was not working, see above. When we removed it from LocalSettings.php, we could use SMW. When we placed its call after the inclusion and activation of SMW in LocalSettings.php, SMW continued to work. See also bug 11238.

Table and image flow / Image alignment
Tables and images have all of their text forced below, as if they were followed by: Also, images that are right aligned: end up on the left side of the page and all text is forced to appear after the image. Is this a limitation of htmldoc or something that can be fixed in the extension? -- 66.83.143.246 18:53, 13 September 2007 (UTC)
 * I've temporarily fixed the image problem by wrapping them into a table, but this does not solve the general problem why htmldoc is forcing breaks after floats. 66.83.143.246 13:28, 14 September 2007 (UTC)


 * It's most likely not a limitation of htmldoc but actually the extension, probably to do with the parser sanitisation process. Comment out the line that removes the temp file and check the html in that.. Is not pretty.  Suspect

Blue boxes on images and empty table of contents entry
htmldoc was adding blue borders on images that didn't have the frame attribute since they all had anchor tags around them and a slot in the table of contents for the mediawiki generated table of contents. I removed these with the following regular expressions in the execute function:

Prince : A better alternative to HTMLDOC?
Is it possible to use Prince instead of HTMLDOC?

Prince seem to works the same way but it also supports CSS.

Seem to be working great with MW 1.11.0 after modifying the PdfExport.php.

 * Download and install Prince


 * Download the PHP5 Prince Accessories


 * Move prince.php into the PdfExport folder

require_once( 'prince.php' ); // make a temporary directory with an unique name // NOTE: If no PDF file is created and you get message "ERROR: No HTML files!", // try using a temporary directory that is within web server space. // For example (assuming the web server root directory is /var/www/html): // $mytemp = "/var/html/www/tmp/f" .time. "-" .rand. ".html"; $mytemp = "/tmp/f" .time. "-" .rand. ".html"; $article_f = fopen($mytemp,'w'); fwrite($article_f, $html); fclose($article_f); putenv("HTMLDOC_NOCGI=1");
 * In PdfExport.php, add the line:
 * Remove the following section in PdfExport.php:

header("Content-Type: application/pdf");
 * 1) Write the content type to the client...


 * 1) uncomment this line if you wish acrobat to launch in a separate window
 * 2) header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $page));

flush;


 * 1) if the page is on a HTTPS server and contains images that are on the HTTPS server AND also reachable with HTTP
 * 2) uncomment the next line
 * 3) system("perl -pi -e 's/img src=\"https:\/\//img src=\"http:\/\//g' '$mytemp'");

passthru("htmldoc -t pdf14 --charset iso-8859-1 --color --quiet --jpeg --webpage '$mytemp'");
 * 1) Run HTMLDOC to provide the PDF file to the user...

unlink ($mytemp); $prince = new Prince('actual path to Prince executable');
 * Replace with: (Don't forget to put in the actually path to Prince executable)
 * 1) Path to Prince executable

$prince-&gt;convert3($html);
 * 1) Convert an XML or HTML string to a PDF file,
 * 2) which will be passed through to the output buffer of the current PHP page.

header("Content-Type: application/pdf");
 * 1) Write the content type to the client...

header(sprintf('Content-Disposition: attachment; filename="%s.pdf"', $page));
 * 1) uncomment this line if you wish acrobat to launch in a separate window


 * Then sit back and enjoy the magic :)
 * Images works !!!!!
 * You can even tell Prince to use the main.css from your skin and make the pdf export look just like the actual wiki.
 * It is also easy to use your own css to make the pdf look very professional. Check out the samples section for some great inspiration.
 * The only major draw back is the license cost for running on server. It is only free for personal use.


 * yes... USD 1900 for academic license... too much for me :-) And HTMLDOC isn't HTML4.0 compliant (i.e. no CSS!). Thus, no PDF from wiki pages, at the moment... --GB 22:13, 26 November 2007 (UTC)

PdfExport ERROR if set User rigths
I tried to use my own MW for giving PDF file to another software. An external software passes the appropriate URL to explorer and the PDF is ready.

If user rights is default there is no problem. After I changed the user rights (see below), there is not any content in the generated PDF file, except the navigation menu on the left-hand side of the wiki's page.

I set the user rights: $wgGroupPermissions['*'   ]['read']         = false; $wgGroupPermissions['user' ]['read']        = true; $wgWhitelistRead = array("Main Page", 'Special:PdfPrint', 'Special:Userlogin',);

How can I get the whole content of the page? Can I change somehow the USER ID in the PdfExport.php? Any other solution?

Anonymous Access for Images to Work
For htmldoc to render the images it requires anonymous access

Since the file needs to be saved locally in order to remove the wiki escape characters that would otherwise cause htmldoc to fail…and the file contains absolute urls to the images.. it is in fact the server that is requesting the page.. not the user.

This is of particular importance for windows users who have enabled remote auth or alike, since anonymous access has to be disabled for these to work.

My current work around is to setup a second website under iis that allows anonymous access however only by the server's ip address, then setup a host entry that uses the anonymous site ip and the live site hostname. Then when the server goes to connect to the URL it gets anonymous access to the images and they are included in the PDF.

An alternative MAY be to setup an application pool that uses a user credential that you have setup on the wiki.. but don’t know if this will work as htmldoc is run at commandline so most likely the connection will be servername$ Suspect 06:29, 7 December 2007 (UTC)


 * Seems complicated. What I did on my site is simply put a condition in the LocalSettings file to enable authentication only if the request comes from anything else than localhost:

if ($_SERVER['REMOTE_ADDR']!='127.0.0.1') { require_once( "includes/LdapAuthentication.php" ); ... authentication code continues ... } --Guimou 03:58, 12 December 2007 (UTC)


 * Hmm, dont think that is going to work in a Windows installation, since the image references are absolute, the PHP code isnt even executed..IIS is blocking anonymous access to the images.. BTW, I couldnt get the application pool setup to work -- Suspect

Working code for MW 1.11 on Fedora 8
The code published on the "extension" page works most of the time but does not output images.

Also, on our server (Fedora 8, MW 1.11.0) the URL associated with the Print As PDF command in the toolbox sometimes has %0A tacked on at the end, and not %0D%0A as DavidJameson reported on his server.

I therefore ended up using the code in Extension_talk:Pdf_Export above as PdfExport.php, corrected line 103 to read ?><a href="<?php echo htmlspecialchars( str_replace('%0A', '', $monobook->data['nav_urls']['pdfprint']['href'] )) ?>"><?php and changed line 60 to read $bhtml = str_replace ('/images/',$wgServer .
