automatic handling of negative values in image visualization when in Log scaling #83
If one visualizes an image containing negative values (common in ALMA or in Hi-GAL) and uses Log scaling, the visualization gets screwed up (flat). this can be manually fixed by clicking on the "..." button and setting the minimum value to 0, or a small positive value.
It would be desirable that the systems is able to handle this automatically (similarly, e.g., to DS9)
