I am planning to draw a rectangle around any rectangular objects it detects. isRectangle method works great for that. But to make a for loop or something similar, I need to know the number of blobs detected. Is there anyway to find that? something like blob.length?

The current development version (so anything after 1.3.x) also has a .count() on features now as a shortcut to get the length.
