Re: [Zope] Including images into stx

4 Mar 2002

      Thanks Mike,

Meanwhile I found the problem in the stx_to_html code.

Just for other people who might get into the same problem:

change the code: st = StructuredText.Basic( text ) into
st=StructuredText.Basic( text.document_src() )

and all things will work out fine.

Regards, Tom

Are there other ways to include images inside stx?
This is an ugly, ugly, ugly solution, but it works for my limited
needs (see
http://www.cae.tntech.edu/help/unix/x11/putty_xwin32_tunnelling for an
example).
In the directory lib/python/StructuredText, find the file
StructuredText.py -- edit it as follows:
Change the 'def ctag' stanza to something like:
def ctag(s,
         em=regex.compile(
             ctag_prefix+(ctag_middle % (("*",)*6) )+ctag_suffix),
         strong=regex.compile(
             ctag_prefix+(ctag_middl2 % (("*",)*8))+ctag_suffix),
         image=regex.compile(
             ctag_prefix+(ctag_middl2 % (("-",)*8))+ctag_suffix),
         under=regex.compile(
             ctag_prefix+(ctag_middle % (("_",)*6) )+ctag_suffix),
         code=regex.compile(
             ctag_prefix+(ctag_middle % (("\'",)*6))+ctag_suffix),
         ):
    if s is None: s=''
    s=gsub(strong,'\\1<strong>\\2</strong>\\3',s)
    s=gsub(image,'\\1<center><img src="\\2"></center>\\3',s)
    s=gsub(under, '\\1<u>\\2</u>\\3',s)
    s=gsub(code,  '\\1<code>\\2</code>\\3',s)
    s=gsub(em,    '\\1<em>\\2</em>\\3',s)
    return s
In my copy of the file, this is right above the 'class
HTML(StructuredText):' declaration, and all I've changed is inserting
an image= line into the def, and a corresponding gsub line shortly
thereafter.
Now, anytime I put --some_image_name-- in structured text, I get a
centered image. Example from above:
Start up X-Win32, and cancel out of the **New Connection Wizard**.
Right-click the X-Win32 icon in your system tray, and select
**XConfig**. Select the Security tab and add 127.0.0.1 to the
X-Host list. Check the boxes labeled **Access Control** and **Use
XAuth**, then click the **OK** button at the bottom.
--xwin32_security_tab_gif--
As I said above, ugly, ugly, ugly. Images blindly centered; no alt,
height, or width tags; etc. Also breaks anytime I upgrade Zope. And
did I mention it was ugly? But it does at least work.
