#4216: [with patch, needs review] use sage-native-execute to run 'convert' in
animate.py
------------------------+---------------------------------------------------
Reporter: jhpalmieri | Owner: somebody
Type: defect | Status: new
Priority: minor | Milestone: sage-3.2
Component: graphics | Keywords: animate, convert, sage-native-execute
------------------------+---------------------------------------------------
On my Mac, I was getting this error with the animate command:
{{{
sage: a = animate([sin(x + float(k)) for k in srange(0,2*pi,0.3)],
xmin=0, xmax=2*pi, figsize=[2,1])
sage: a.show()
dyld: Symbol not found: __cg_png_create_info_struct

}}}
In the discussion <http://groups.google.com/group/sage-
support/browse_frm/thread/526afa1bcc4b7ad5>, it was suggested that 'sage-
native-execute' should be used to run the 'convert' command, and this
seems to fix the problems.
Please check this on several different platforms.
