I am trying to draw lines between all centroids. the pensize of the line would be related to the size of the blobs/centroids being connected.

I can get the values from cv.jit.blob.centroids and jit.iter them to use the values to draw things in the jit.lcd.

but I am stumped on how I would loop through the centroids list to get at the values to have lines drawn from each centroid to every other centroid.

any help or small sample patch showing how to loop through the values would be of a great help.

I can get the values from  cv.jit.blob.centroids and jit.iter them to use the values to draw things in the jit.lcd. 

with i = 0 to length(centroidList) loop
   with j = 0 to length(centroidList) loop
     send linesegment xi,yi,xj,yj to jit.lcd
   end
end

any help or small sample patch showing how to loop through the values would be of a great help.

and you can store the centroid with max's version of an array, coll.

then you can send a sequence of array[index] to the coll and slice them for

ye, you need a loop.
and you can store the centroid with max's version of an array, coll.
then you can send a sequence of array[index] to the coll and slice them for
the segmentline you want to create.

check the modified [p cv.jit.blobs.centroids.draw]

check the modified [p cv.jit.blobs.centroids.draw]
this is not ideal, but works
