venice is a mask utility program that reads a mask file (DS9 or fits type) and a catalogue of objects to:
- create a pixelized mask,
- find objects inside/outside a mask,
- or generate a random catalogue of objects inside/outside a mask.
The program reads the mask file and checks if a point, giving its coordinates, is inside or outside the mask, i.e. inside or outside at least one polygon of the mask.
