Extension talk:AnyWikiDraw

AnyWikiDraw Project Status
I really like this very much and I would appreciate to use it. I know it is experimental, but please add a description, what still is to do until it is working.

Actually it would be nice to know about still missing functionality before installing, ...


 * Hi. I have added a "To Do" section to the page.

AnyWikiDraw PHP Errors
..., like the not working save-function of drawings: anything goes, but drawings are not saved and don't show up after finishing and they don't show up when trying to edit them again


 * Apart from the known refresh problems, the save function is working. Did you enable uploading of image files to your wiki? If you are not able to upload a SVG, PNG or JPG file using the upload page of the wiki, then the drawing applet can't do it either.
 * There is a controlling function in the applet. But it might not be checking for all possible error cases. Can you please check, if PHP prints an error message on the error log of the web-server?

I get a Parse error: syntax error, unexpected T_OBJECT_OPERATOR in .../extensions/AnyWikiDraw/AnyWikiDraw.php on line 105 What version of PHP is required?


 * I have implemented this extension with PHP 5.0 in mind. I am using it currently with PHP 5.0.4.

AnyWikiDraw Can't Find Files
This issue is fixed in AnyWikiDraw 0.11. --Rawcoder 07:23, 28 May 2008 (UTC)

I've set up AnyWikiDraw 0.1 as an extension to MediaWiki 1.9.1. It works fine creating and in saving the file created. However, when trying to reedit an existing file, it gives this message:


 * Couldn't load the drawing: http://www.proper-wiki-name.org/wiki/index.php?title=Special:AnyWikiDraw?Image:Test02.svg.

When the images is actually found here:


 * http://www.proper-wiki-name.org/wiki/images/1/1f/Test02.svg

In other words, the extension seems to work fine to create and save (one time) a new drawing, but not to edit an existing drawing.

Any ideas on how to fix this?

 * Looks like AnyWikiDraw can't handle article paths in the style of {$wgScript}?title=$1.
 * With the current version of AnyWikiDraw, you need to run MediaWiki with article paths in the style of {$wgScript}/$1.
 * I am going to take a look at this problem for the next version of AnyWikiDraw. But I can't tell you right now, when the next version will be released.

I hacked away at the AnyWikiDraw code and got the code to generate a full URL for the image. Yet for some reason the JVM still fails. The URL now looks something like this: http://cicswiki.org/cicswiki1/index.php?title=Special:AnyWikiDraw?image=/cicswiki1/images/e/ea/Test.gif Is this supposed to work? In other words - if the image variable refers to a real file - is AnyWikiDraw supposed to be able to edit the file?

 * The question mark may only occur once in the URL. If you change your code to insert an ampersand "&" before the word "image" it might work - at least the editor should show up with this file - saving the edited image is another story and thus might still break.
 * Also note, that AnyWikiDraw does not support the GIF format, you need to use JPG, PNG or SVG.

AnyWikiDraw working (fairly well) on MW 1.9.1
This issue is fixed in AnyWikiDraw 0.11. --Rawcoder 07:23, 28 May 2008 (UTC)

I've managed to get AnyWikiDraw to work fairly well on MediaWiki 1.9.1 and it really is a tremendous extension &mdash; IMHO much better than any of the other programs for making diagrams and drawings on MediaWiki.

The problems I've found are as follows:


 * Something in AnyWikiDraw is causing this message to appear on the background to the Special:Allmessages page: "Warning: call_user_func_array [function.call-user-func-array]: First argument is expected to be a valid callback, 'AnyWikiDraw::loadMessages' was given in /home/ .. (my path) .. /wiki/includes/Hooks.php on line 114". Doesn't seem to be a big deal because I've got this page tucked away were the public rarely sees it.
 * SVG works fine. Can edit, save, and reedit. However, thumbnails don't show up on "recent uploads" page. Instead there is the message "Error creating thumbnails".
 * PNG, jpg can produce diagrams, but can't be re-edited.

The SVG drawings are compact and of good quality, better than PNG or jpg, anyway.

 * Hi C4duser. I am glad you like AnyWikiDraw so far. :)
 * I am very interested to get a look at the code changes you made for MediaWiki 1.9.1. I am looking forward to make AnyWikiDraw work with versions higher than 1.7 of MediaWiki. My intention was to go directly from 1.7 to 1.12. But if you have it working with 1.9.1, I don't mind at all. ;)
 * The warning on call_user_func_array is probably caused by API differences betwen MediaWiki 1.7.x and 1.9.x. There might be some rewriting needed to accomodate for this.
 * For creating the thumbnails, I had copied and pasted lots of code from MediaWiki 1.7.x into the AnyWikiDraw plugin. Maybe we need to copy and paste the same code sections again from MediaWiki 1.9.x. This needs careful checking though.
 * How exactly does the re-editing of PNG and JPG images fail? AnyWikiDraw doesn't store vector data in a PNG or JPG file (for example, like Adobe Fireworks does in a PNG file). This is why, after reopening a PNG or JPG file, everything which has been drawn so far, becomes part of the background image. So, on re-edit, it is only possible to draw over the background image.

 * In the meantime, I got a beta of AnyWikiDraw 0.11 working on MediaWiki 1.9.3.
 * I think, it didn't work for C4duser, because of the {$wgScript}?title=$1 issue. I have resolved this issue now for MediaWiki 1.7.1 as well.
 * I am now working on support for MediaWiki 1.12. I need to rewrite the plugin, because somewhere between MediaWiki 1.9 and 1.12 the plugin API has changed.
 * --Rawcoder 04:56, 26 May 2008 (UTC)
 * I installed version 0.11 and the same errors persist. However, I appreciate the improvements to the interface (collapsing panels). I have made no changes to the code and have the extension installed directly on MediaWiki 1.9.1.  The PNG and JPG files cannot be re-edited, giving the following error message: "Couldn't load the drawing" "Couldn't load image from file "java.io.BufferedInputStream@5dd915".."  The PNG and JPG files show up in the thumbnail gallery of images, but SVG files do not. However, SVG files can be re-edited and work just fine otherwise.  The same error message on the Special:Allmessages page persists. Thanks. --C4duser 19:54, 30 May 2008 (UTC)

No image after save
Hi Rawcoder. Great extension. I have a problem : after drawing save (test) there is no image on the wiki article.

Can you help me because this extension is fundamental for me. Thanks very mutch.

 * I think, you need to install ImageMagick on your computer. Does the generation of the preview image work, when you upload an SVG image using the Upload special page?

Hi Rawcoder

Effectively i dont have Imagemagick on my internal serveur. Is it possible to help me to install and configure this software (where is located for example). Is it a spécial configuration on mediawiki ?Is this soft installed on the web serveur or on the clients ? Thanks to help me
