[PD] forcing focus to and minimizing the GEM window

Wed Mar 14 21:52:27 CET 2007

Hola,

Do anybody know a way to mininimize the GEM window, and then restore it and 
bring it to front?
I mean, obviously, controlled by PD message, not by mouse.

Either in full screen or not: both would be useful to me (assuming I can 
have a borderless screen-size zero-positioned gem window)

Oh, sorry: in Windows XP.

THE LONG VERSION:

It's because I need to run two applications: GEM and a Flash projector, and 
I need to be able to switch between them remotely via (for example) MIDI 
events.
At any moment, one of the two would be visible and doing things, and the 
other invisible and waiting.
So, I thought I may have one of the two on front and the other on bottom, if 
only I could just minimize and restore one of the two.

As far as I know, there's no way to minimize and restore the flash projector 
window (only switch between fullscreen and window mode) via programming; so 
I just hoped there was a way of doing it in GEM.

Or, any tool that could tell Windows to switch to a certain task would do 
the job (as long as I can send a midi or TCP/IP message to this tool). Or a 
command-line tool would do, since I could execute it from flash. However, 
all this goes far O.T.
I just thought it would be nice to let you know why the heck I'm asking that 
:)

Thank you in advance
M.

You need one value for each pixel row in an image?  That will probably
require writing a custom external to do that.

PixelTango builds on top of Gem, so there is no realy difference here.
(i don't think that PixelTango comes with an abstraction for Gem that
does right out-of-the-box what you need)

not necessarily.
if you have plenty of cpu left, you could go for Gem's [pix_dump], which
dumps the entire image as a list into "pd-space". then you can do
whatever you want with it (e.g. use iemmatrix to calculate what you need).

another solution with Gem might be to use [pix_resize] with a width of 1
and then [pix_dump] the image "column".

other libs:
i am sure there are some simple resizing mechanisms in GridFlow. if you
need to do more complicated stuff on the data, GridFlow might be a good
choice anyhow, since you could stay in grid-space rather long and only
do the conversion into pd-space at the very end.

pdp/pidip:
i don't know, but i am sure there are solutions here too.

so it really depends on what else you want to acchieve.
if it has to run on w32, then the solutions are limited.
(but i don't know)

Yes, i was fighting with that a while too...

which platform are you using ?

Hello everyone,

I tried google and it was no help, and the server for the list archive
seems to be down temporarily.

Anyway, I'm giving a free (as in free beer) workshop in Chicago in
about 16 hours, on the basics of digital synthesis. I have decided to
use Pure Data to give my presentation, and use mostly non-commercial
software.

However, I'm still missing the following for demonstrating "proper"
subtractive synthesis:
1. Good, out of the box "analog-sounding" filters. I'm using [moog~]
right now, but I'm not all that satisfied with the sound compared to
the filters in my favorite VST's ...
2. Band-limited square and sawtooth waveforms.

For teaching purposes PD is great, and ideal for my demonstrations.
But as it is, I'm having to use VST's within PD in order to
demonstrate a "nice sounding" synth. It would be nice to show that PD
can do it without using stuff built in Steinberg's format. That would
also let the Mac people replicate my work, if they are interested.
Note, nobody in the workshop has ever tried Linux, except me, so Linux
plugins are not helpful in this case.

I will post my patches after I give the workshop, though they are
nothing fancy ... just basic:
sequencer - oscillator - vca - filter. Good for demoing though, I'm
starting with additive first, then subtractive.

~David

Hi David,

See in the audio help patches: J07.oversampling.pd for bandlimited
sawtooth oscillation.

hello david

everything i know about this topic i know from the list. i think the
archives can be really helpfull in that specific case.

however, i think the list archive is up again. try this link:
