RasterTypeConversion

The RasterTypeConversion operator allows changing the data type of raster data. It transforms all pixels into the new data type.

  1. Applying the operator could lead to a loss of precision, e.g., converting a F32 value of 3.1 to a U8 will return a value of 3.

  2. If the old value is not valid in the new type it will clip at the value range of the new type. E.g., converting a F32 value of 300.0 to a U8 will return a value of 255.

Parameters

ParameterTypeDescriptionExample Value
