Subject [sis] branch geoapi-4.0 updated (3b01827 -> 6092c0a)
Date Fri, 12 Apr 2019 18:22:43 GMT
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 3b01827  Fix an IllegalArgumentException when creating one-banded image of type DataBuffer.TYPE_INT.
Remove ScaledColorSpace from public API (provide a static method instead). Remove ColorModelFactory.getNumBands(ColorModel)
method.
     new c0944af  Revert commit a685c8a1bf0b412a544713f1ceda9749a995a5d6 (compute linear regression
by minimizing errors in grid indices instead than geospatial coordinates). The reason is because
the "compute linear regression in reverse way" approach brings more complexity and is not
sufficient anyway; we still needs a more sophisticated iterative algorithm in InterpolatedTransform.Inverse.
     new 40a34e9  Add explanation about the "compute linear regression in reverse way" approach
that we reverted in previous commit, so if we want to try it again we know which commit to
revert.
     new 6092c0a  First draft of an InterpolatedTransform algorithm using derivative (Jacobian
matrix) for deciding in which direction to compensate for errors. Not yet enabled.

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.
