[Moin-devel] Macro that generates a dyamic png

[Karolina Lindqvist]

I spent a day, a few weeks ago, to develop a very specialised macro for my 
wiki. It takes a description, and create a graphic picture from it, on the 
fly, with the help of gd. I tried a macro first, but I could not figure out 
any way to send the .png back to display it, without writing it to disk 
first. Finally I made it into an action, since they can give a png on the 
fly. But now the action name shows up on the bottom of each page, and it is 
not really an action you can do, but a macro.

Here is an example how I call it:

 [[HTML(<img 
src="http://shakti.ath.cx/ShaktiWiki/?action=WeaveImage&box=20&solv=0:1&tramp=121212&knyt=x-:-x">)]]

So what I would need, is either how to send a PNG 'on the fly' from a macro, 
or how to make an action that is not listed at the bottom of all pages.
