RS_AsArcGrid

Introduction: Returns a binary value (byte array) representing an ArcGrid image for each input raster. ArcGrid only supports a single band. If your raster has multiple bands, you need to specify which band to use as the source.

Possible values for sourceBand: any non-negative value (>=0). If not given, it will use Band 0.

Format:

RS_AsArcGrid(raster: Raster)

RS_AsArcGrid(raster: Raster, sourceBand: Integer)

Return type: Binary

Since: v1.4.1
