I have a floating point raster (standard deviation in db) and want to rescale it from 0 to 255.
When I use Raster > Data Conversion > Convert Datatype and select uint8 as an output and linear stretch (95%) i get the following pattern:
I wonder where these gaps come from. I chose another no data value (0 and 255) but it had no effect on the data.
The image looks fine, click the red text to compute accurate histogram, could be a rendering error. Also check the histogram in the “Analysis” menu.
Last option would be reopening the output or even redoing the data conversion, if it persists, you have found a bug, yet I would guess it is a rendering error of the histogram.
well, that was easy
Thank you for this hint - the properly calculated histogram looks fine.
