which produces an [x,y] coordinate pair. The click is correct if it falls
within a region specified. This region is a union of rectangles.
Lon-CAPA requires that each <imageresponse> has a <foilgroup> inside it. That
doesn't make sense to me (Ike). Instead, let's have it such that <imageresponse>
should contain one or more <imageinput> stanzas. Each <imageinput> should specify
a rectangle, given as an attribute, defining the correct answer.
Lon-CAPA requires that each <imageresponse> has a <foilgroup> inside it.
That doesn't make sense to me (Ike). Instead, let's have it such that
<imageresponse> should contain one or more <imageinput> stanzas.
Each <imageinput> should specify a rectangle(s) or region(s), given as an
attribute, defining the correct answer.

regions="[[[10,10], [20,30], [40, 10]], [[100,100], [120,130], [110,150]]]"/>
Regions is list of lists [region1, region2, region3, ...] where regionN
is disordered list of points: [[1,1], [100,100], [50,50], [20, 70]].
If there is only one region in the list, simpler notation can be used:
regions="[[10,10], [30,30], [10, 30], [30, 10]]" (without explicitly
setting outer list)
Returns:
True, if click is inside any region or rectangle. Otherwise False.
