embedding subset of fonts when saving to pdf

Hi,

I have a problem with large file-sizes of plots saved to pdf, when using
rcParams['text.usetex']=True

Files are very large (~150kb for simple line plot with some mathematical latex expressions) as all fonts are fully embedded into pdf. When resulting pdf is postprocessed (e.g. as is http://zeppethefake.blogspot.com/2008/05/embedding-fonts-in-pdf-with-ghostscript.html), so that only subset of fonts is embedded, file size is reduced drastically(e.g. from 150kb to 15kb).

Is there a way to enable embedding of subset of fonts in matplotlib?

I am using matplotlib version 0.99.3.

Did anyone else experience similar problems/found solution?

Thank you for info/assistance!
Simon

Have you tried setting the rcParams "pdf.fonttype" to 3? That should subset the fonts.

Also, the Cairo backend supports font subsetting.

Setting 'pdf.fonttype'=3 had no effect, embedded fonts are of fonttype=1 nonetheless. I guess that pdf.fonttype parameter is used only when matplotlib uses it's own engine to render latex, and not when text.usetex=true is used.

Cairo backend is not support when text.usetex=true (only Agg, pdf and ps according to documentation)

Ah, yes. That is all true. I'm not sure what options there may be in that case.

Thank you for the info.

I added the issue to the github for now.

I will inspect the source whether there is an easy way to add subsetting of fonts for usetex=True case as well.
