You could try using Quicktime Player pro to export a frame from your
composition.
There are options to set the size, so you should get close to what
you need.

The most likely way to make this work is by modifying one of the
sample code projects to render into a large view and saving it to
disk as whatever format you would like.
The thing to remember is that Quartz Composer is a hardware
accelerated motion graphics format, and 2500x3500 RGBA is a lot of
video ram, maybe more than a PowerBook has ;)
Initially I thought I could help you with a program called Quartz
Debug found in the Developer Performance Tools directory. Close QC
and run Quartz Debug, then choose "User Interface Resolution" from
the Tools menu and play around with the DPI setting before opening
QC again. Unfortunately, copying out an image still uses real
screen pixels, so I was not able to copy out an image larger than
my monitor :-D maybe you will figure out a way to open the
composition larger than your screen's resolution using this tool.

would be a cool function, indeed.

Hello Jeff,
Resampling my picture is not exactly what i had in mind, I am
really talking about resolution and not size, since a picture of
2500 x 3500 pixels is about what i need for a professional letter
(A4) size printout.
Whatever the final outputting size, i will always need 300 dots
per inch (publishing industry standard res), while a screen
resolution is 72 dots per inch.
There lies the gap... For example, a screenshot on Powerbook
15.2" at 72dpi, converted to 300dpi, gives a final size of 11 cm
x 7 cm. My goal is to produce a 42 cm x 30 cm final picture, at
300dpi, without resampling - pure pixel for pixel. I can very
well afford to lose velocity, since i am computing still images!
This explain my earlier idea of displaying only a part of the
picture before screen-shoting. But, M. Latour, couldn't we have
this somehow automated inside the program, adding an option to
export .tif or .png?
Thank you none the less for making me discover rasterbator, which
is actually a very cool piece of software!

Hello,
For printing large format images, you may want to try a free
program called "rasterbator." You can download it here: http://
arje.net/rasterbator or if you don't have a PC, you can use the
web service here:http://homokaasu.org/rasterbator/
It will take a "normal" sized image and blow it up to even wall
sized dimensions.
Hope this helps!
Cheers,
- J
