First, thanks to Gabriele for the pointer on the after-load image resizing
trick. We manage to make it work, though some bugs occurred.
Since ka-Map! Main development language is English, support for non-english
characters is null. That produced some bug on the xhr.js file when using the
call function, as well as the utf-8 encode added to the url-encoding on the
To make a short story, the legend.php would first create the image, the
mapfile, the group and layer name contains spaces and acute characters (such
as é), the legend_dim would receive url-encoded string, that, once decoded,
would be in utf-8
losing my real layer name.
To prevent that, we edited xhr.js to use POST methods when send 3 and more
parameters to prevent url-encoding as well as specified a charset for its
header (on setRequestHeader). We also converted utf-8 string into iso-8859-1
(using PHPs iconv).
If anyone need the base code provided by Gabriele, see
You might as well add a similar piece of code when the legend is first
generating, near line 450 of kaLegend.js.
Heres the code I used
call('legend_dim.php?map=' + this.kaMap.currentMap + '&scale=' +
this.kaMap.getCurrentScale() + '&g=' + oLayer.name, this , evalFromPhp);
Thats it for the image size bug.
Also, as Gabriele pointed out, $oMap->drawLegend method does not take
account of the MAXSCALE/MINSCALE properties of the CLASS inside the layer.
It does seem to accept the layers one though. I guess that is a bug that
will/should hopefully be fixed.
I shall also review the script to check for code injection/ajax abuse,
since there is an eval used
It seem obvious to me that not much input
validation is made on ka-Map!, eventhough not much is to be inputted :D .
So thanks again.

Objet : kaLegend image size problem...
I already had this problem... See the thread named kaLegend bug fixed in the
archives of july 2007.
However seems that the problems occurs when you use MAXSCALE/MINSCALE
Hope this helps..
