Dear ImageJ list,

My question is : How are managed/processed the NaN values of a 32 bits image
?

Two practical examples :
- plotting
- filtering.

When plotting its seems than an infinite negative value is attributed to NaN
values.

When filtering (median filter) all NaN values are disapeared.

It would be nice for me if  somebody could provide some information about
NaN values management when datas are processed and plotted.

Thanks.

Philippe
