GridReset
org.ecoinformatics.seek.gis.java_gis.GridReset

This actor is for transforming some range of values in a grid to some other value. If the current value of a grid cell is within the given range (minval, maxval) and a 'newval' is given, the values in the range are set to 'newval'. If 'newval' is empty or the input string is an invalid representation of a double, then the current value is multiplied by the multiplicationFactor and the additonParameter is added and the new value is the result. (Actually, a new grid is returned, rather than revising the current grid.)

minvalParameter
The minumum value in a range where the grid pixel value is to be reset.

maxvalParameter
The maximum value in a range where the grid pixel value is to be reset.

newvalParameter
The new value of pixels in the (minval,maxval) range. If absent, transform the existing value

multiplicationFactor
if newvalParameter is empty, multiply the existing value by this factor

additionParameter
if newvalParameter is empty, add this to the existing value

useDisk
Boolean setting to determine whether or not to use disk for storing grid data rather than putting all data in RAM arrays
