Textile support for scale inlined images

Added by Dirk Heinze at 2013-03-21 10:17 am


I use redmine and chilliproject for different tasks.
And i work with an Retina Mac.
So my screenshots are much bigger today than earlier.
In Issues and Wiki-Articles the images are to large in chiliproject.

In Redmine it's easy to fix this with


But this doesn't work in chilliproject.

Has anyone an idea how to fix this?

I use: ChiliProject (Mysql2) and Redmine 2.2.3.stable.9007 both with PlugIn WikiNG 0.3
The scaling tag works without WikiNG.

you're right - seems to be a missing handling for the size tag:


Currently the support for image height is commented out / incomplete - see:

lib/redcloth3.rb line 945

    def inline_textile_image( text )
        text.gsub!( IMAGE_RE )  do |m|
            stln,algn,atts,url,title,href,href_a1,href_a2 = $~[1..8]
            htmlesc title
            atts = pba( atts )
            atts = " src=\"#{ htmlesc url.dup }\"#{ atts }" 
            atts << " title=\"#{ title }\"" if title
            atts << " alt=\"#{ title }\"" 
            #size = @getimagesize($url);
            #if($size) $atts.= " $size[3]";

The function getimagesize() seems to be missing and should have the task to evaluate the {width:xxx} part of the URL.

=> after a look into Redmine sources, the both lines are disabled there, too... so the error is a layer below that...

The next step would be to open an issue ticket so Felix or Holger can check and possibly solve that...

Or can I port it back from Redmine to CP? (With some hints I can do that maybe even with my noob-skills in Ruby?) ;-)

Thank, you Chris for the fast reply.

I checked the code between redmine and chilliproject.
In this section has red mine the same comments.
So the solution should be at another place.

But i think in the moment, that the other changes in lib/redcloth3.rb may be a solution.
I will check this on the coming weekend, when no production runs on the server.

Textile optionally supports arbitrary CSS, this has security implications though and could lead to XSS attacks, thus it is disabled in ChiliProject. IIRC it's just a switch to flip to get it back, I can't remember off the top of my head where it is though.

problem solved!

I'v updated the lib/redcloth3.rb with the version distributed by redmine 2.2.3.

And i'v disabled the style filtering by change in lib/redmine/wiki_formatting/textile/formatter.rb line 30 from true to false.

But the is an tiny bug in combination with tables, if you embed the image in an table.
Than all scales below 100% produces thumbnails.
