Module numdisplay.displaydev
displaydev.py: Interact with IRAF-compatible image display
Modeled after the NOAO Client Display Library (CDL)
Public functions:
readCursor(sample=0)
Read image cursor position
open(imtdev=None)
Open a connection to the display server. This is called
automatically by readCursor if the display has not already been
opened, so it is not generally necessary for users to call it.
See the open doc string for info on the imtdev argument, which
allows various forms of socket and network connections.
close()
Close the active display server. Called automatically on exit.
Various classes are defined for the different connections (ImageDisplay,
ImageDisplayProxy, UnixImageDisplay, InetImageDisplay, FifoImageDisplay).
They should generally be created using the _open factory function.
This could be used to maintain references to multiple display servers.
Ultimately more functionality may be added to make this a complete
replacement for CDL.
