PROPERTY_KEY
public static String PROPERTY_KEY
- The key to a property table, to store or access the cached
bounding box of a stroke.
StrokeBBox
public StrokeBBox()
apply
public static Rectangle2D apply(TimedStroke s)
- Compute the stroke's bounding box using the minimum and maximum
x, y values in the path. If the specified stroke already has a
bounding box in its property table, just return the cached box.
This assumes that the stroke does not change. Otherwise,
calculate the bounding box and stores it in the stroke's property
table so that it won't need to be recalculated.
FIXME - this caching is extremely dangerous for incremental
recognition. check number of points in stroke?
have a force recompute function?
bboxNoCache
public static Rectangle2D bboxNoCache(TimedStroke s)
- Return the bounding box, but do not cache the
results in the stroke's property table.
