[Playerstage-developers] RTK2, libplayerc changes

[ahoward <ah...@po...>]

Hi folks:

I've made some changes to RTK2 and libplayerc that you should watch out
for.  They work okay for me, but I havent tested them thoroughly.

RTK2
----

I've made done some fairly significant internal re-organization to make
maintainance easier, and added support for exporting jpeg images (in
addition to the ppm and xfig export that was already there).  As a
consequence, some function names have changed:

  rtk_canvas_export_image()

no longer exists; it has been replaced with

  rtk_canvas_export_xfig()
  rtk_canvas_export_ppm()
  rtk_canvas_export_jpeg()

The jpeg export option requires libjpeg, which is standard in most
distros.


libplayerc
----------

Data packets that arrive during request/reply operations are now shunted
into an internal queue so they can be read out by the standard
playerc_client_read() function.  Previously, data packets that arrived
during request/reply operations were effectively lost (although the
registered handlers did get called).  The impact of this change is that
one can now be guaranteed that playerc_client_read() will return *all*
data packets, irrespective of whatever configuration requests your client
might by issuing.


	Later,
		A.
