Releases · nipy/PySurfer

Support for Python 3.3 and up.
A new alpha keyword to the Brain constructor now controls
opacity of the rendered brain surface.
The curv keyword to the Brain constructor has been
deprecated. To replicate previous behavior when curv was set to
True simply omit the curv keyword. To replicate previous
behavior when curv was set to False, simply set the
cortex keyword to None. To ease transition the curv argument
will still be caught and processed, but it will be removed in a
future release.
The cortex keyword to the Brain constructor now also accepts
a valid color specification (such as a 3-tuple with RGB values or a
color name) to render the cortical surface in that color without
rendering binary curvature values. Additionally it now also accepts
a dictionary with keyword arguments that are passed on to the call
to mlab.pipeline.surface.
Brain.save_movie now uses the imageio library, eliminating the need
to manually install ffmpeg. imageio has been added as an optional
dependency which can be installed with
$ pip install pysurfer[save_movie].
Brain.save_image now has the option to save with alpha channel and
antialiasing.

Values that were previously selected using a config_opts
dictionary in the Brain constructor are now keyword arguments.
This should make it easier to use tab-completion in IPython, and will
generally simplify your scripts. To ease transition, a config_opts
argument will still be caught, and its entries will be used (overriding
the keyword arguments), but it will be removed in a future release.
The ability to set default values in a config file has been removed.
While convenient, this approach encourages code that is not fully
reproducible. While existing code that was written expecting a config
file will still run, the visualization will fall back to default values.
These should be updated directly in your plotting scripts.
Figure size is now specified only through the size keyword argument
of :class:Brain. To make a rectangular window, pass a (width, height)
tuple. Passing a single value to size will still make a square window.
The cortex keyword argument can now be a mayavi colormap name or
a (colormap, min, max, reverse) tuple for full control.
Morphometry plotting was made more flexible with the ability to pass
a specific colormap and anchor points for that colormap. Additionally,
the default anchor points now use robust statistics to give better
values.
Contour overlay plotting was made more flexible by adding keyword arguments
to control whether a colorbar should be shown and whether existing contour
overlays should be removed before plotting.
