Re: [Matplotlib-users] CMYK
Thanks everybody for the input. As I see the answer is no, but it could be implemented. I did an extensive search, but I even struggle to find a good and practical solution how to convert a VECTORPLOT RGB to CMYK on a linux system. (One way I often found would be the Adobe suits, which I do not have.) I gave mpl_ps_cmyk a go, but execution failed, and the page looks dated. Furthermore, Adobes seems to provide ICCs only for Windows and Mac, but not for Linux. ImageMagick rasterizes the figure, the same with GIMP. I agree that this should be done on the publisher's side, but as a matter of fact it is the requirement of some journals. Is there really no practical way to do this? How do others convert RGB plots to CMYK? (Importing my data into Matlab and plotting them there cannot be the only possibility!) Thanks everybody again, much appreciated!

(Importing my data into Matlab and plotting them there cannot be the only possibility!) Funny story about that. I was submitting an article to an IEEE journal once. IEEE's submission process for images gives back fairly useful error messages, and it told me that my images (that I generated from matplotlib) needed to be in CMYK format. I had access to Adobe Illustrator on my wife's computer, and used its tools to convert those files to CMYK, and resubmitted it to IEEE's submission page. The error message I got back? Images need to be in RGB format I forget what I did to resolve this problem (I think I did some funky eps--ps--pdf--eps thing, I don't remember), but what I submitted was certainly RGB, so, go figure...

Re: [Matplotlib-users] Problem with PatchCollection and FancyArrowPatch?
FancyArrowPatch behaves quite differently from normal patches. Most importantly, the path must be reevaluated during the drawing time, so a normal PatchCollection, which evaluate the paths during the instance creation, won't work. i.e., you need a new Collection class. Below is a very incomplete implementation of FancyArrowPatchCollection, just for a demonstration purpose. And I recommend you to open a wishlist ticket at the issue tracker (https://github.com/matplotlib/matplotlib/issues ). Regards, -JJ class FancyArrowPatchCollection(PatchCollection): def set_paths(self, patches): self._patches = patches def get_paths(self): paths = [] for p in self._patches: p.set_transform(self.get_transform()) _path, fillable = p.get_path_in_displaycoord() paths.extend(_path) return paths def _prepare_points(self): import matplotlib.transforms as mtransforms transform, transOffset, offsets, paths = PatchCollection._prepare_points(self) return mtransforms.IdentityTransform(), transOffset, offsets, paths On Thu, Jan 31, 2013 at 6:33 AM, Skipper Seabold jsseab...@gmail.comwrote: Hi, Trying to figure out why these two do not create the same plot.
