Help document for ALL the Raster Functions

[Ranga_Tolapi]

Hi,

Where can I find the REST API help document for ALL the Raster Functions. I have gone through http://resources.arcgis.com/en/help/rest/apiref/index.html?israsterfunctions.html but it doesn't contain the help for ALL the raster functions. I was looking for help about "Mask Function".

Basically, I want to know, how to pass the parameters for "Mask Function" using
1. REST API
2. ArcMap ("Server Functions" tab for Image Service layer properties window).
