[Octave-bug-tracker] [bug #65384] image clim and climmode properties improperly set for RGB and integer cdata

[Rik]

Follow-up Comment #6, bug#65384 (group octave):


> ok, out at m-code level, yes that whole block seems unnecessary.  but i
don't think the caxis('auto') is needed.

Sorry, I didn't make myself clearer.  The 'caxis' command was merely to show
what Octave was getting wrong, and how to recover Matlab behavior.  The root
cause is that setting 'clim' property to any value changes the mode to
'manual'.  I think we fix that by simply removing the block of code in image
which is unnecessarily setting the 'clim' property.

Separately, Matlab says "The clim function only affects graphics objects that
have the CDataMapping property set to "scaled". It does not affect graphics
objects that use truecolor or have the CDataMapping set to "direct"."

So, TrueColor (RGB) should not be changing "clim" nor using it to affect
display.
