Dear list members,
Every "modern" OS comes with dozens of useless fonts, so that the
current font drop-down list in most programs is overcrowded with fonts
one never will use. Selecting a useful font becomes a nightmare.
In an attempt to ease the selection of useful fonts, I began looking
into sorting fonts using some statistical techniques. I summed my ideas
on the OpenOffice.org wiki:
http://wiki.services.openoffice.org/wiki/User_Experience/ToDo/Product/Font_Categories
Of course, there is NO guarantee that something useful will emerge, but
at least someone has tried it.
I would like to try various statistical methods using R, unfortunately,
I got rather stuck in my attempts.
I wish to compute:
- the length of a standard string for the various fonts
- the weight
- some variance-type measures for the OX and OY-axis
- DCT (possibly analysing separately the low/high-frequencies)
- maybe some other measures
[I am open to suggestions]
1.) First and foremost, I need the list of fonts installed on my system.
[I am using Win2k]
Is there any way to get it automatically in R?
IF this is not possible, I could create one by hand, though this is
cumbersome, but the 2nd problem is more severe.
2.) How do I create/get the 2D-pixel matrix?
I need of course the f(x,y)-image representation for a standard text.
The following seems a rather ugly hack and I do not actually have the
exact text-box size.
> png(file="mytestfontimage.png")
> plot.new()
> title("This is a font")
> dev.off()
strwidth() and strheight() seem to be able to look into the fonts. But
how do I get the pixels?
And more importantly, can I get also the exact pixel-matrix?
[Though, it seems there are no pixel-units in strheight()/width(), but I
might be wrong on this.]
3.) The image-analyses capabilities of R are rather limited.
I couldn't find any reference to a DCT transform (or other techniques).
A search yielded only the following thread:
http://tolstoy.newcastle.edu.au/R/help/06/01/19615.html
As I do not know (and have access to) mathlab, I am rather confined to
R. Which is not bad, but I need a lot of help to accomplish this task.
Any help is highly appreciated.
Sincerely,
Leonard Mada
