[Qgis-user] How to Create the Data Type Unsigned Int 8 bit in QGIS 2.0 Raster Calculator?

[jorgepsantos2002]

Hello All,

How I choose the output data type in QGIS 2.0? In older versions, the
plugin* RasterCalc* from GIS Lab shows a box to select the Data Type for
output raster operations.

I need to rescale a raster changing the pixel depth from 16 bits to 8 bits.
QGIS 2.0 Raster Calculator outputs rasters in *Float32*. I need my data in
*Unsigned Int 8 bit* or *Byte*.

*My formula:*

( ( "LC82180762013253LGN00_B6 at 1"  - 0)*( 255-0 )/( 51171 - 0 ) ) + 0

Works on QGIS 1.8 with plugin RasterCalc
