[Zope] dynamically generated image buttons

[sean.upton@uniontrib.com]

This functionality is really depending on the typography support on your
server.  I believe that ImageMagick's convert program can be set up to use
Freetype and TTF fonts.  This may be able to suit your needs, but you would
need to code an external method to utilize ImageMagick to create the buttons
for you (well, to call 'convert' at the command-line with arguments for the
text and font you want to use); you would likely want to cache buttons,
since auto-generated images can be expensive.  Even with this, you would
need to create a mechanism for making these images accessible to the
templates you are using (and thus the users browsing the pages).  

That said, there may be ways to do this without rolling it out all on your
own, but I've never tried anything like this:

On the low-end, if your requirements are simple, and your browser clients
can support it, you may seriously want to consider use of CSS and DHTML for
making your buttons, since it could be done on the client without all this
heavy lifting.  Alternately, on the high-end, you may want to consider a
product like Macromedia Generator or Adobe Altercast to do this for you on a
separate server.

Hi all,

it is exist some thing to automatically generate swap image buttons with
Zope? I mean that you have two source images (for onmouseover and
onmouseout) and that "thing" will "burn" text to that images from some
variable (eg., Title).

I have migrate from M$ Frontpage where that feature is incorporated and in
Zope is missing to me.

Many thanks, J. Lukesh
