Subject: Re: [PD-dev] Pd-extended-0.43 appearance
That would be great, to make it really work well, we need to move
as much of the
GUI handling to pd-gui and have pd talk only using pd messages. So
something
like this:
pd-gui
------
\ click in a box to edit the text
\ edit the text in the box "osc~ 500"
\ click on canvas to create the new object
\ pd-gui sends message to pd
pd
--
\ pd receives ".x872342 updateobj 5 osc~ 500
\ pd recreates obj #5 with "osc~ 500"
Things like that. This also means that we can use Tk's built-in
zooming
support, so we can have patches be fully zoomable to any arbitrary
size.
If you're talking about the canvas scale subcommand, keep in mind that
fonts and bitmaps don't get scaled.
I'm talking about tk scaling. I am pretty sure fonts get scaled, but
I don't know about bitmaps.
Also, you stated below that box sizes are hard coded in both
(current) extended and
vanilla. Does that include box width? If so, that would mean that
the entire pd
diagram-- except for the specific font used-- would appear pixel
exact on any
platform. But the OP is to the contrary, so does hard-coded mean
minimums are
set and extra space is allotted as needed?
The sizes are specified per character.
Maybe a better question is-- could you point me to the spot where
the hard-coded
values are specified?

Oh -- I misunderstood.
I like the idea of making this an option (eitehr growing to the
standard
box size or huggung the actual size of the font we're getting).

Those can just be hard-coded to a certain size in pixels, then
the font
can be measured to fit into those boxes. That's the approach that
Pd-extended has been doing since 0.41 or 0.40, I forget which.
That's
how it works in Pd vanilla 0.43 too.
To handle font size differences, the box sizing needs to be
handled in
Tcl, as well as the mouse and click handling. For something like
clicking to edit an object box, Pd only needs to know what the
new text
is once the editing is done.
Roman, I think the thing to do is to measure the boxes for each
release
in question on each platform so we know where the problem lies.
That's
what I did back in the day to make the boxes the same pixel sizes.

Last I checked things were completely inconsistent and no version
("normal"
or extended) got the same font sizes across platforms. If anyone
can
figure out how to make that work robustly I'm all for it. One
headache
is that I've tried to make PD use natively available fonts
which
everyone
will have - and there simply don't seem to be natively
available fonts
with
comparable sizes between Pc/Mac/linux.

I'll check that again. It seemed to me that the Pd-vanilla
looked
very
much the same on OS X and Linux, at least since 0.43. I
haven't
checked
Windows yet. Also I had the impression that Pd-vanilla
doesn't have a
different appearance across different Linuxes anymore. I
remember it
being dependent on some DPI setting, but I haven't
encountered that
issue anymore.
I tried to get these changes into vanilla, but I guess
Miller didn't
want them. I've already spent a lot of time on it, so
I've moved on
since it works in Pd-extended. There should be a whole
history of
the
discussion on pd-dev, i.e. the details of the issues. I
don't
remember them, I'm sure it was some annoying technical
details.
Also, you can see the changes that pd-extended makes to
puredata but
looking at the pd-extended.git in the
'patch_series' branch.
Thanks for the explanations.
Roman
