# RS_SetPixelType

Returns a modified raster with the desired pixel data type.

The `dataType` parameter accepts one of the following strings.

* "D" - 64 bits Double
* "F" - 32 bits Float
* "I" - 32 bits signed Integer
* "S" - 16 bits signed Short
* "US" - 16 bits unsigned Short
* "B" - 8 bits unsigned Byte

<Note>
  If the specified `dataType` is narrower than the original data type, the function will truncate the pixel values to fit the new data type range.
