<br>
I have a question that may be more of a matplotlib question than a yt<br>
question, but it's an issue with some yt generated figures I have, so I<br>
thought I'd ask it here. I think there was some discussion of this on<br>
the list a while ago but I can't find the thread.<br>
<br>
When I output images that include colorbars in vector formats (like pdf<br>
and eps), I get these little lines running across the color bar. It<br>
goes away if I output the image in a rasterized format (like png). I<br>
wanted to output my images in vector format (as pdfs) so everything<br>
looks nice and sharp. I've figured out how to just rasterize the color<br>
bar. However, I don't want to rasterize the color bar labels, and the<br>
way I've implemented it, the labels get rasterized too. It seems in<br>
figure objects (and maybe axes objects?) there is a way to specify the<br>
order that items get drawn and/or rasterized (through the zorder and<br>
rasterized_zorder keywords); I've played around with this but haven't<br>
been able to get it to work. The color bar is a Colorbar object and it<br>
doesn't seem like this class allows for adjusting the rasterization<br>
order of things.<br>
<br>
I've pasted an example script here:<br>
<a href="http://paste.yt-project.org/show/2504/" target="_blank">http://paste.yt-project.org/show/2504/</a><br>
I'm probably going to give up on this soon, but any advice people have<br>
would be greatly appreciated.<br>
