virtual Bool casa::PrincipalAxesDD::setActiveZIndex_ ( Int zindex ) [protected, virtual]

Set internal index (activeZIndex_) into the list of DMs (which cache individual drawings), according to passed animator index.

This is called by conformsTo() (via conformsToZIndex()), and serves to 'focus' the DD on the current WCH's zIndex. Returns True if there is only one frame, in which case activeZIndex_ is set to 0. Thus a single frame is considered to apply to any canvas zIndex setting (this allows a continuum image to be blinked with a chosen channel of a spectral image, e.g.). If there is more than one frame, the passed zindex is stored, and the return value will indicate whether it lies within the DD's current number of frames.

Reimplemented from casa::DisplayData.

CoordinateSystem casa::PrincipalAxesDD::itsCoordSys [private]

This is the working CS which is transposed and has axes removed all over the place.

(dk note: The authors explain this poorly, and don't seem to make the distinction even for themselves very well: there are two relevant coordinate transformations here, not just one. itsOrigCoordSys defines the world space for the data pixels. itsCoordSys defines the world space for the canvas. Control and setting of the canvas CS is poorly modularized, and the DDs remain involved in too much of the canvas's coordinate translation chores).
