Blobs - README

This extension creates a texture of blobs.  Blobs are randomly
scattered over a rectangle (user input).  Individual blobs
are randomly generated as described below.

Inkscape v 0.92 on Debian Gnu-Linux.

The pop-up has two tabs, Each and All.

Each:

Blobs are built starting with a number of (interior) points,
in a Gaussian distribution.  The (almost) convex hull is built
and then (somewhat) smoothed with splines. In the above sentence,
each parenthesis indicates an input parameter, called out in the
pop-up "interior" "concavity" "bluntness".

Also, "size of a blob" sets the /standard deviation/ of the
distribution, so blobs are typically 3 times larger than the
value.

Bluntness = 0.3 makes pleasingly round, mostly convex blobs. 0.4 makes them more
concave. 0.6 - 1.0  they're getting more and more pointy. 2.0 - 10. and they
grow appendages like hot-air balloons.  0.1 makes the corners pretty sharp.
0.0 and it's down to the convex hulls that are the basis of the blobs, that
is, polygons.

Concavity goes from 0 to 1.  0 tries to be completely convex.  Increasing
the number allows more interior points to be used so the shape becomes
more complex, as well as more branchy.

All:

The work area x,y values specify a rectangle in which to place
the blobs.  Their centers are restricted to this area, so blobs
may spill outside it.  Centers are placed randomly.

Blobs are on their own layer "Blob layer".  There may be several.
