If someone has created an image service in ArcGIS with function templates in order to process on the fly... How would you bring that data into QGIS and be able to switch between functions? In ArcMap you open the properties and select the functions tab... But how would one do this in an OpenSourceGIS utilizing the Image Service?
PS it can be accessed through a WMS/ WFS
But is the 'functions template' an ESRI only product when dealing with image services??
