Feature request #6188
Let the user fine tune stretching values in raster properties/style
|Pull Request or Patch supplied:||No||Resolution:|
When the user selects Use standard deviation and selects
a value for the sd, the calculated min,max values are greyed
and cannot be modified. If the user then selects Custom min/max values,
the previously calculated values are erased. This used not to be
the case in previous versions.
Min/max values calculated from sd ranges are very useful as a first
guess, but very often must be fine tuned. Thus not erasing the calculated values
is an important aid.
A critical case is when
color composites of several images must be compared, as all of them
must have the same stretching.
