[Qgis-user] How qgis calculate the min/max of floating point raster

[Nicolas Cadieux]

Hi, 
That value is only good the first time you open the file. Then, a XML is created and that statistic changes with the display value of the raster.  Don't know why.  The best way is to use gdal info with the processing tools.

	Hi,
when I add a flot raster to qgis canvas, and see the starting property settings,
I see the qgis has populated the min/max for ever band.
But this vales are not corresponding with the results from
gdalinfo raster.tif
So I guess they are calculated with some algorithm.
Is this algorithm knowed ?
Thx,
