Cannot read in composite ROIs about read-roi HOT 3 CLOSED

Another person got the same issue:

I have just found your program and it is just what I need, but I am having problems with a particular imageJ ROI type called "composite". I can see from the ROI manager description:
1 Roi_name Composite 124 98 35 44 none none 0 17 0 17 0

when I read it using your program:

{'Roi_name': {'type': 'rectangle', 'left': 124, 'top': 98, 'width': 35, 'height': 44, 'arc_size': 0, 'name': '

Roi_name', 'position': 17}}

I imagine that the "composite" type is not in the ROI_TYPE posibilities and the rectangle is selected when an unknown is found. I would assume that the properties of the composite should be the same as the freehand. I have attached an example in order to help you.

If anyone wants to submit a PR about it, I would be happy to review and merge it.

Should be fixed.

Thanks for reporting this, @OSchoppe. Full support for composite ROIs was added in v1.6.0.

Composite ROIs have a 'paths' dictionary key, which contains a list of all the paths in the composite ROI. Each path is a list of co-ordinates for the nodes along the path. As per the .roi file contents, the paths are not closed, so you will have to repeat the starting co-ordinate at the end of each path if you wish to close the path. Each path begins at its top-most point, and I believe the paths are listed in order of their top-most point but I am not sure on this. The nesting of the paths is left for the user to determine. Each outermost path describes a region of pixels which are included in the ROI, whereas a path immediately inside this describes pixels which are excluded (and a path inside that describes pixels to be included again).
