Thread: [Matplotlib-users] Placing vector eps graphics

Hi there,

I want to place an eps graphic I created in Inkscape in a plot. The final
image is supposed to be a vector eps as well. I looked up the forum but just
found the option with the Image (PIL) library which obviously rasterizes my
vector image. And I use the Tex option so I cannot just save as SVG and do
the compositing stuff in Inkscape.

The placing of the image is straight forward and fine documented (with
additional axes and imshow), so it is just a problem of importing a eps
vector image.

I would be very grateful if someone could help me with this issue.

Thanks!
Jakob

Unfortunately, matplotlib doesn't support importing vector images of any 
sort.

Your best bet is to, as you suggest, do the compositing in an external 
tool, such as Inkscape.  Version 0.46 and later claim to support PDF 
import, you could try that.  (Though I haven't tried it with a 
matplotlib plot personally, so no promises...)

Cheers,
Mike

You may use PyX for compositing two eps images. It is not a gui
application like inkscape.
But it is one of the best option I know for eps compositing.

It you could save from inkscape as .svg instead of .eps, you might be
able to modify Jae-Joon's trick to directly include this svg into a
matplotlib-generated svg file. See

.

Thanks all for the fast reply.

The tip with PyX is working fine!
So its very easy to combine different eps files! 

If someone is interested, try something like:

from pyx import *
c = canvas.canvas()
c.insert(epsfile.epsfile(0, 0, "1.eps"))
c.insert(epsfile.epsfile(0.5,0.2,"2.eps",scale=0.5))
c.writeEPSfile("output")

Thats all!

Ciao Jakob
