layer opacity does not work in mapserver layer #15

Closed savelov closed 5 years ago

savelov commented 5 years ago

since mapserver 7.0 opacity option is in composite section of layer, and does not work inside layer https://mapserver.org/mapfile/composite.html#composite

Simple transparency / opacity is achieved by only specifying the OPACITY parameter (this achieves the same effect as the legacy LAYER OPACITY parameter):

currently opacity is set in openlayers API, but for google kmz layer need to specify opacity in mapserver to generate correct bitmaps with alpha channel

setOpacity() method should be used
