Unsharp Filter Characteristics Options

[Derek Wright]

Peter

Please will you describe the characteristics of the Unsharp filter - comparing it to the filter in say Gimp which has three settings Radius, Amount and Threshold. By adjusting the settings especially the Radius setting one can alter the strength of the filter.

What is the equivalent PMview settings.

Is it possible for the user to create a user defined unsharp filter and or do you have any plans to add a user customisable unsharp filter.

Thanks for PMVIEW
