Problem with fill and latex interpreter?

I noticed that I began having trouble with saving figures that contain transparency.

First, the figure appears on the screen as desired. Then just as the figure is being saved, the filled color disappears, leaving just the lines. The image that is saved contains only lines, not the fill.

Eventually discovered that the source of the problem is setting the 'DefaultTextInterpreter' to 'latex'.

Is this a bug?

set(0, 'DefaultTextInterpreter', 'latex')
figure
polyg = rand([2,20]);
h = fill(polyg(1,:), polyg(2,:), 'k');
set(h, 'facecolor', 'r', 'facealpha', 0.5);
print('-dpng', 'test_fill_alpha')

Using Matlab 8.0.0.783 (R2012b) on a Mac OS 10.8.5.

What behavior do you put in question?

Thanks, I should have been more explicit in my post. It has been updated.

I suggest using this excellent tool for exporting figures: http://www.mathworks.com/matlabcentral/fileexchange/23629-exportfig

In your case run:

export_fig test_fill_alpha -png

You can add arguments like -transparent for transparent borders and -nocrop for no automatic cropping of the borders.

Paul,

Thanks for the suggestion. I do use export_fig when print fails.

My question is more whether or not this should be considered a bug or not.
