layer->draw() method

[SUBSCRIBE MAPSERVER-USERS Y. Calcagni]

Hi everybody!

Can someone explain me the goal of the phpmapscript layer->draw() method. I
was trying to make code to display raster legend icon and thought this
method should be useful.
Indeed, I was thinking it should produce a single layer image but I saw in
the doc that it returns an integer and requires an ImageObj as parameter.
So, if anyone have sample handling this method...

Thanks in advance.
