matlab - Exporting figures as vector graphics in .pdf-format using HG2-Update and 'painters' renderer is not working properly

Question

I'm using the still undocumented HG2-Update to create my MATLAB plots, because they just look that much nicer.

(Source: Yair Altman)

Actually, using the current version Release 2013b it works quite nicely and there are not much issues. Except one wants to export the figures as vector graphics (renderer: '-painters'), especially as pdf.

I use the commands:

saveas(gcf,'test.pdf','pdf')

or

print(gcf,'test.pdf','-dpdf')

There are rendering issues, the print does not contain the whole figure and some parts are cropped or non-default fonts are not recognized.

But I'd really like to stay with HG2 and I'd still like to use vector graphics. Is there any solution or workaround?

Exporting vector graphics using the yet not official HG2-Update is quite an issue. The .pdf-export is still totally screwed up. What is working fine is the .svg-export, apart from that the boundary box is not set properly.

The long workaround would be: Save the plot with '-dsvg' (print-command) or 'svg' (saveas-command) as vector graphic, open the file in the open source application Inkscape and save again as .pdf with the Export area is drawing checkmark set.

Quite complicated, so I found a way to do it via command-line directly from Matlab (Inkscape still required!):

filename = 'test';
inkscapepath = '"C:Program Files (x86)Inkscapeinkscape.exe"';

%// save as .svg
saveas(gcf,filename,'svg')
%// open and save with "export-area-drawing" set via command line
system( [inkscapepath ' ' filename ...
         '.svg --export-area-drawing --export-pdf=' filename '.pdf'])

It takes some time, but works without any known issues for now.

Additionally delete the svg-File afterwards:

delete([filename '.svg'])
