 Great!  Though I think it'd have taken me a while to figure that one out!

 I gotta agree. Is this (and the solids object) documented anywhere?

No, and it probably won't be any time soon.  Rasterization here is a 
last resort work-around for buggy pdf renderers. The solids object is 
mentioned in the colorbar docstring as something one can modify for such 
workarounds (an alternative is given), but perhaps without saying what 
kind of a thing it is.

 Hi all,

 So I figured out the magic of rasterized=True, which is *really*

 However, the colorbar doesn't seem to accept rasterized=True, so

 there another way to get the colorbar colors rasterized?

Try:

cb = colorbar()
cb.solids.set_rasterized(True)

Incidentally, the lines in the pdf are an artifact of most pdf viewers, 
not a bug in the pdf file.  It is possible that there is some way to 
construct the pdf files such that this does not happen, without 
introducing other artifacts, but we have never found one.

[Matplotlib-users] rasterized colorbar

2012-10-26 Thread Jody Klymak 

Hi all,

So I figured out the magic of rasterized=True, which is *really* helpful!

However, the colorbar doesn't seem to accept rasterized=True, so there are 
little lines every facet (zoom on the attached pdf).  Is there another way to 
get the colorbar colors rasterized?
