License:

You must license your ArcGIS Server as an ArcGIS Image Server to use this resource.

The info resource returns information about the associated raster such as its width, height, number of bands, and pixel type.

At 10.7 and later, the raster info resource supports ICS To Pixel. child resource. It returns geometric transformation coefficients that can be used to perform image coordinate system [sensor: Frame] to pixel (column, row) transformation.

The raster info resource supports the following child resources:
