Update of bug #50466 (project octave):
Status: None => Confirmed
Operating System: Microsoft Windows => Any
_______________________________________________________
Follow-up Comment #1:
The function is known to be missing which is why it is in the unimplemented
list. If you try at the command line you get
hgtransform
warning: the 'hgtransform' function is not yet implemented in Octave
Please read <http://www.octave.org/missing.html> to learn how you can
contribute missing functionality.
This is a different, and more appropriate error message, than if the name in
question doesn't refer to any known variable or function.
octave:2> abc
error: 'abc' undefined near line 1 column 1
Implementation, ideally, would be in C++ as a new graphics object primitive
(like line, or surface).
However, you might be able to work up a replacement in an m-file that uses
hggroup. Child graphic primitives can have their parent properties set to an
hggroup and you can add the necessary property (Matrix) using addproperty to
make the hggroup resemble an hgtransform. After that, you would need to add a
callback function that listens for changes on the hgtransform Matrix property
(addlistener()). The callback functions would then use the transform Matrix
to alter the Data properties of the child objects.
