In Pd Vanilla and possibly Pd-l2ork, tk menus and widgets should "do the right
thing" because of something called tk scaling:
http://wiki.tcl.tk/8484
In Pd-extended, "tk scaling" is hard-coded to "1" in pd-gui.tcl, but if you
remove that line things should scale up accordingly. (Or reveal bugs in tk if
things look wacky as a result.)
You won't be able to scale iemgui sizes in any flavor of Pd. They are
specified in pixel units. There is a canvas "scale" subcommand but the catch
is that text items (i.e., most of the content of a patch) doesn't actually get
scaled. Worse, tk canvas seems only to support integer font sizes, making it
burdensome to try to use canvas scaling and manually tweak the font sizes to
match. (I think Pd-l2ork currently does the reverse-- you choose a different
font size and it picks a corresponding scaling factor, though I don't know if
it actually uses the "scale" subcommand or not.)
So burdensome is scaling text on a tk canvas that someone just decided to make
their own mono-spaced vector font in tcl/tk using canvas curves, demo'd here:

In Pd-l2ork, canvas zooming is essentially one very tricky step away. It has a
scalable canvas text item called "ptext", but unlike the normal text item it
doesn't have editing features (i.e., showing the insertion caret, highlighting
text, etc.). So someone would have to code that up manually. But once that is
done you could scale the entire canvas, or even rotate/skew it if you're into
that kind of thing. :)
Btw-- the potential use case you mention shows the weakness of using images in
patches. For example, if you made a button that toggled between two png images
when clicked, that button would look blurry when you scale the patch up.

Hi
Recently, a few models of so called ultrabooks with comparatively high
display resolution (up to 3200x1800px) are available, even with
affordable prices. While the specs sound teasing, I wonder how Pd is
going to behave on those. I'm especially interested in the situation on
linux.
This might be rather a Tk question, but it is possible to scale all Pd
graphics evenly, so that the appearance will still be comfortable and
all menu and patch fonts will readable? Setting the font size in patches
won't really help as this scales only the boxes and there content, but
not the menus, the iemguis and also not the distance between boxes.
Is someone with a hi-res display stuck with lowering the resolution when
the goal is to do some patching?
