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 11c6b74 Avoid the call to `Arrays.binarySearch(…)`. It has been
identified by profiling as a performance bottleneck (in the context of
`Isolines`).
new e5142b5 Retrofit `DefaultIterator` into `PixelIterator`. This change
allows slightly better encapsulation (more fields can be made private) and
reduce the need to create `WritablePixelIterator` when only read operations are
desired. The previous abstraction level was apparently not needed in practice.
new 4f8f236 Add `BandedIterator`, a specialization of `PixelIterator` for
the case of images using a `BandedSampleModel`. This is an attempt to resolve a
performance bootleneck observed during `Isolines` calculations.
new eceea7f Make possible to use `BandedIterator` with multi-tiled
images. It required to retrofit `LinearIterator` into `PixelIterator`.
The 3 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.
