In the ArcGIS Javascript API, according to the documentation (1), a ImageLayer's pixels can be filtered using the RasterFunction class. However, according to the documentation (1), the pixel's "value" is used for filtering. So only the pixel's "value" is selected on. Is there a way to filter on any attribute the ImageLayer's pixel might have, and not just the "value" attribute?
I need to select on multiple attributes, or at least something other than just "value," of each pixel to make a useful query.
I've been trying to find the answer to this for months. Thanks!
