[Octave-bug-tracker] [bug #63060] imread returns logical data for 8-bit

Update of bug #63060 (project octave):

                 Summary: image() handle cannot be set cdata with an imread()
result => imread returns logical data for 8-bit TrueColor PNG image

    _______________________________________________________

Follow-up Comment #4:

FYI, Matlab also doesn't allow logical values for TrueColor data.  This code
works:


img = rand (65,65) > 0.5;
imshow (img)


But this code does not


img = rand (65,65,3) > 0.5;
imshow (img)


The error message says that logical data must be 2-D.

Hence, the problem seems to be that imread is returning logical data, when it
should be returning TrueColor data.  Re-titling bug report.
