Returns:
One of SCALE_LINEAR, SCALE_LOG, etc.

setScaleMethod

public void setScaleMethod(int scaleMethod)
Description copied from class: FITSImage
scaleMethod must be one of SCALE_LINEAR, SCALE_LOG, etc. The image must be redrawn after this method is called for the change to be visible.

Overrides:
setScaleMethod in class FITSImage

rescale

public void rescale(double min,

Description copied from class: FITSImage
Rescales the image with the given min and max range values. sigma is used for the inverse hyperbolic sine scaling as the value (in the range of the data values with bZero and bScale applied) at which the behavior becomes more logarithmic and less linear.
