This is an automated email from the ASF dual-hosted git repository.
desruisseaux pushed a change to branch geoapi-4.0
in repository https://gitbox.apache.org/repos/asf/sis.git.
from 728f70e Implementation of a java.awt.Shape backed by an array of
coordinates that we can handle more easily than with java.awt.geom.Path2D. It
introduce a class hierarchy similar to the OGC geometry classes (Polyline,
Polygon, MultiPolygons), but it is not the intent to provide an OGC geometries
implementation now. Those classes are needed for simplifying `IsolineTracer`
(in a next commit).
new fb43846 Replace the use of `java.awt.geom.Path2D` by `PathBuilder` in
`IsolineTracer`. It simplifies the algorithm and allow us to resolve the
remaining spikes that we saw in isolines.
new 11c6b74 Avoid the call to `Arrays.binarySearch(…)`. It has been
identified by profiling as a performance bottleneck (in the context of
`Isolines`).
The 2 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails. The revisions
listed as "add" were already present in the repository and have only
been added to this reference.
