Dear Csaba,
You need something like:
coord = newArray(20,48,59,13,101,40,75,77,38,70);
makePolygon(coord[0],coord[1],coord[2],coord[3],coord[4],coord[5],coord[6],coord[7],coord[8],coord[9]);
I guess it depends a little how many sides your polygons will have how to implement this.
Best wishes

Subject: array in macro functions
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.
How can I use list of coordinates for making polygons?
Many thank in advance!Csaba
