Rescale cell values such that the minimum is zero and the maximum is one.
Rescale cell values such that the minimum is zero and the maximum is one. Other values will be linearly interpolated into the range.
The min parameter will become the zero value and the max parameter will become 1.
Values outside the range will be set to 0 or 1.

Rescale cell values such that the minimum is zero and the maximum is one.
Rescale cell values such that the minimum is zero and the maximum is one. Other values will be linearly interpolated into the range. Cells with the tile-wise minimum value will become the zero value and those at the tile-wise maximum value will become 1. This can result in inconsistent values across rows in a tile column.
