Re: [Matplotlib-users] CMYK images

While not a full solution, I have been playing with a ps backend that saves images (and only images) in CMYK color. lcms is required for color transform. http://github.com/leejjoon/mpl_ps_cmyk For example, import mpl_toolkits.ps_cmyk plt.savefig("test_cmyk.eps", format="eps_cmyk") Regards, -JJ

[Matplotlib-users] Not scaling patches.

Hello, I've used matplotlib for a while but never had cause to ask a question until now. I am trying to add a patch to an axis, but would like the patch to remain the same size when, interactively, I resize the resulting figure. I am using TkAgg, and trying the following: >>> import matplotlib.pyp

Re: [Matplotlib-users] CMYK images

This is starting to get off topic from matplotlib, but it is relevant to creating good EPS figures... When using ImageMagick to transform from to an EPS, your results will be much improved by using the parameter "-density 288". This increases the resolution (and thus results in a much bigger file

Re: [Matplotlib-users] CMYK images

Thanks. I think it will be useful to have "cookbook instructions" to perform this task on the Matplotlib web site. Meanwhile, is there anyone that can provide those instructions, please (I've not any of these tools installed yet, and I don't know them). ? 2010/8/26 Daπid : > Image Magick and Ink

Image Magick and Inkscape seem to work for this. Probably the first one is easier to automatize in batch processing. On Thu, Aug 26, 2010 at 4:21 PM, Michael Droettboom wrote: > matplotlib does not have any built-in support for any color spaces other > than RGB.  You would need to use an external

Re: [Matplotlib-users] CMYK images

matplotlib does not have any built-in support for any color spaces other than RGB. You would need to use an external tool (if such a thing exists) to convert color spaces. Mike On 08/26/2010 10:06 AM, Michele De Stefano wrote: > Is it possible to export EPS images with the CMYK color scheme ?

[Matplotlib-users] CMYK images

Is it possible to export EPS images with the CMYK color scheme ? There are several technical journals that require this format (for example Geophysiscs, one of the most important geophysical journals, The Leading Edge, and, I think, Geophysical Prospecting only to cite some of them). -- Michele
