PHP Mapscript fixes for 4.6.0-beta2

[Bart van den Eijnden]

Hi Mark,

it might be the best idea to open up a bug report per fix in the Mapserver bugzilla so these patches don't get lost.

I also don't know what the policy is for keeping SWIG mapscript in sync with PHP/Mapscript, so your changes might need changes in the SWIG mapscript as well.

Best regards,
Bart

Hi everyone,

I've just been looking at dynamically creating symbols on the fly using PHP
Mapscript, and found a couple of bugs which I believe I have fixed with the
attached patches. The patches are against the file
mapserver-4.6.0-beta2.tar.gz which I downloaded from
http://mapserver.gis.umn.edu.


        1) symbolObj has no imagepath property

        This was fixed by copying the code from mapsymbol.c to allow the
imagepath property to be set via mapscript. I
        was a little unsure about how the current path should be handled, so
at the moment it assumes that the path to the
        GIF/PNG is absolute without considering the current path from the
environment.

        2) symbolObj->setPoints() doesn't correctly set
symbolObj->sizex/sizey

        Using setPoints() to load an array of points for a vector symbol was
not correctly setting sizex/sizey to the
        maximum extents of the symbol. Hence all symbols were being drawn
with a size of 0 and did not appear to be
        visible. This was fixed by borrowing the code from mapsymbol.c to
set sizex/sizey to the maximum extents of the
        symbol as points are added to the symbol.


Many thanks,

Mark.
