Process Styles

Get full data for any styles. The idea is that we load all the needed styles into the ['styles'] key of the map object, and keep a reference in ['layer_styles'] and ['layer_styles_select'] for layer specific styling.

TODO: Overall, this is not a great approach to managing styles.

Parameters

$styles: Array of map styles ( <style_role> : <style_name> | <style_array> )

$layer_styles: Array of layer styles ( <layer_name> : <style_name> )

$layer_styles_select: Array of layer styles ( <layer_name> : <style_name> )

$map: Map array

Return value

$processed Array of processed styles ( <style_name> => <style_array> )

1 call to _openlayers_styles_process()

openlayers_build_map in ./openlayers.module
