render(...)


render( (Map)arg1, (Image)arg2, (int)arg3, (int)arg4) -> None :
    
    Render Map to an AGG Image32 using offsets
    
    Usage:
    >>> from mapnik import Map, Image, render, load_map
    >>> m = Map(256,256)
    >>> load_map(m,'mapfile.xml')
    >>> im = Image(m.width,m.height)
    >>> render(m,im,1,1)
    
    

    C++ signature :
        void render(mapnik::Map,mapnik::Image32 {lvalue},unsigned int,unsigned int)

render( (Map)arg1, (Image)arg2) -> None :
    
    Render Map to an AGG Image32
    
    Usage:
    >>> from mapnik import Map, Image, render, load_map
    >>> m = Map(256,256)
    >>> load_map(m,'mapfile.xml')
    >>> im = Image(m.width,m.height)
