Dear Jan,thank you for your advice. I was afraid that I have to learn another language. But it is probably not possible to learn Java in a week :(

> Hi,i have coordinates of hundreds of irregularly shaped polygons that i want to draw on a single image. I do not have the polygons as ROIs, unfortunately. I want to usea list of coordinates from another software. I managed to import them in an array, but when i wanted to use makePolygon(coord); where coord is an array of all the coordinates of a polygon, i got the failure message: Numer or numeric function is required. When i wrote a list of coordinates one by one in the makePolygon function it worked well, but I do not have the time to write all the many thousand coordinates of many hundred polygons that way.
