LaTeX text processing using "LaTeX low level font commands" in &

Dear John,

Its 3 months later, but rather late than never:

Thanks for the changes!

I worry that this is starting to get hairy -- perhaps we
should look into separating the latex from the code more cleanly.


The LaTeX low level font commands are now accessible using either rcParams[...] or the `matplotlibrc' file instead of a seperate input file as proposed previously.

e.g. in you pylab script file:


rcParams['latex.font.size']='12' # Fontsize, e.g. 10, 11, 12, ...
rcParams['latex.font.baselineskip']='14'# Baselineskip - usually 1.2 x Fontsize
rcParams['latex.font.encoding']='T1' # T1 - Latin 1, etc.
rcParams['']='phv' # cmr - Computer Modern Roman, ptm - Times-Roman, phv - Helvetica, etc.
rcParams['latex.font.series']='m' # m - Medium, b - Bold, bc - Bold Condensed, bx - Bold Expanded
rcParams['latex.font.shape']='n' # n - Upright (Normal), it - Italic, sl - Slanted,
                                        # sc - Small Caps, ui - Upright Italics, ol - Outline

To bypass a specific low level command, set the rc parameter to an empty string, e.g.

rcParams['latex.font.size']='' # Fontsize, e.g. 10, 11, 12, ...

The default fontsize will now be used.

The code added to `' and `' are basically:

            fontcmd = ''
            if rcParams['latex.font.uselowlevel'] == 'True':
                if rcParams['latex.font.size'] and rcParams['latex.font.baselineskip']:
                    fontcmd += r'\fontsize{%s}{%s}' % (rcParams['latex.font.size'], rcParams['latex.font.baselineskip'])
                if rcParams['latex.font.encoding']:
                    fontcmd += r'\fontencoding{%s}'% rcParams['latex.font.encoding']
                if rcParams['']:
                    fontcmd += r'\fontfamily{%s}'% rcParams['']
                if rcParams['latex.font.series']:
                    fontcmd += r'\fontseries{%s}'% rcParams['latex.font.series']
                if rcParams['latex.font.shape']:
                    fontcmd += r'\fontshape{%s}'% rcParams['latex.font.shape']
                fontcmd += r'\selectfont '

(or see attached)

The validations to the added param keys in `' maybe needs some more work...

I think it would be much easier for us to deal with this if
you submit it as a proper patch against CVS and upload it to
the sf site. Could I trouble you to do that?

How do I go about doing that?

I have never used CVS before. (Only RCS for my own stuff.)

I have installed TortoiseCSV (yes, unfortunately I am a win32 user...), but how do I proceed from here...

I started reading the part `Developer CVS Access via SSH' (instead of `Anonymous CVS Access')

I have created a SF login, but can't get past the:

`Log in to' admin page...

Kind regards,
