[mapserver-users] The new composite block in python swig api

[Andrea Peri]

Hi Steve.

Thx for hint.
It dont seem work.
I

Querying the help from python I can see that the "compositer" object
is defined inside the layerObj, but dont seem to have any opacity var
inside it.

I try this:

The compositer object is defined, but seem don be any opacity variable
inside it.

I also check the code of swig inside the file "swiginc/layer.i"
I can see that there is still the setOpacity under layer and the
getOpacity instead
has a 100 value hardcoded.
:(

-----
    void setOpacity(int opacity)
    {
      msSetLayerOpacity(self, opacity);
    }

    int getOpacity() {
      if(self->compositer) return (self->compositer->opacity);
      return (100);
    }

Should I open an issue for this ?

The SWIG interface for layers does reference it in the getOpacity/setOpacity methods but for backwards compatibility reasons. The structure is exposed to SWIG however and should be accessible even without special methods. In perl, something like this should work:
>
>   $layer->{compositor}->{opacity} = 50;
>   $layer->{compositor}->{comp_op} = $mapscript::MS_COMPOP_SCREEN;
