I’m having trouble reading the list of x,y coordinates in a freehand ROI, which I believe should be short integers (16 bits). Is there a description of the header and points format for an ImageJ ROI somewhere? I have an old header description, which seems to work, but I’m not reading the list of x, y coordinates correctly.
The .roi file format is described at the beginning of RoiDecoder.java:
