Details:

Currently the release candidate 7.0.90 under Windows comes bundled with the
latest released image package version (2.12.0.). Via some patches in
mxe-octave to the image package, the image package installs fine (i.e. without
errors during "pkg install") on Octave 7.

But: Running "pkg test image" under Octave 7.0.90 produces many failing tests,
for several reasons. Several of the image package funtions probably not work
at all under Octave 7. A first glance gave me the impression that some changes
to core Octave result in those test failurs.

This issue is ment to collect and eventually solve these test failures. Here
is a short overview of failing unit tests, including a short first comment to
what the problem seems to be:

* @imref2d/contains.m
** something with the error-id
* @imref2d\intrinsicToWorld.m
** something with the error-id
* @imref2d\worldToIntrinsic.m
* @imref2d\worldToSubscript.m
* @imref3d\contains.m
* @imref3d\intrinsicToWorld.m
* @imref3d\worldToIntrinsic.m
* @imref3d\worldToSubscript.m
* blockproc.m
** those should be fixed already in the next image relase
* colorangle.m
** something with the error-id
* graythresh.m
** usage of hist changed?
* im2bw.m
** the "+=" operator seems to be obsolete now
* imfindcircles.m
** usage of hist changed?
* imlincomb.m
** the "--" operator seems to be obsolete now
* integralImage3.m
** changed error message
* label2rgb.m
** something with a function name as parameter
* otsuthresh.m
** something with the error-id

Probably some of those issues are also present in image package functions,
that do not have any unit tests...
