Nils,I saw your bump about this transparency issue. Before moving forward on this, I'd like to know what your use case is. I've attached a mock-up example. On the left is the effect of changing the alpha value of everything to 50% (what you and Christopher had suggested). But it seems to me what you really want is on the right -- making only the figure and axes patch fully-transparent. This is what one would want, for example, when putting a plot on the colored background of a webpage. I don't understand why anyone would want the one on the left, but if you can provide a use case for it, it should be implementable.

Of course, this depends on what you mean by transparency. If you mean to change the alpha of the entire PNG, then yes, the global parameter (or postprocessing) is the way to go. But I'm not sure how useful that is -- that will still lighten things behind the figure and axes patch. A more useful option, IMHO, would be to just make the figure patch and axes patch fully transparent and leave everything else "as is". That avoids the "white box on a colored background" problem.Cheers, Mike Christopher Barker wrote:Nils Wagner wrote:"John Hunter" <[EMAIL PROTECTED]> wrote:I wonder if we should support a global rc alpha....I'd make it an optional parameter to savefig(), but I like the idea. Of course one could pretty easily post-process it as well. -CHB
