Ain't got no problem getting the list of numbers from the rightmost outlet, but don't really understand what each one of those stands for: centerX(weighted), centerY(weighted), size(weighted), minX, minY, maxX, maxY, area. I know [pix_multiblob] makes a matrix to get the results, but I don't know how does that work neither.

Kinda naïve I guess, but ain't got no clue.
Any help would be appreciated.

Could you explain it?
Also, I get a shitload of messages "matrix: row index $1 is out of range".
