high resolution/large format

what's the best way to create/work with high resolution/large format images?

i'm sorry if this is a really stupid question - i basically want "enlarge" some little processing sketches i've done and print them out on a large format printer (i want to make some huge static images).

is there a good way to do this?

i ran into some memory problems (i think) when i just tried to make the display window really large and multiply the tasks (for example make 1000 lines compared to 100).

thank you very much.

Depending on the kind of drawing your doing...

Vector or bitmap images are available to you as options. I've even gone as far in extreme cases of vectorizing bitmaps.

Check the library page for postscript and illustrator exporting.

It really depends on the sketch in question, but you can employ a host of tricks.

Post some code if you have specific queries.

if you are on pc, you can edit the run.bat to increase the memory, but it will eventually run out. casey once told me to just use code to shift the algorithem of whatever you are doing so that it saves multiple frames of one large image and stitch it together in photoshop. it is much more efficient. as for the the vector based stuff in illustrator, i did some tests and it could handle alot, but up your ram! i was using a machine that had 2gigs and it was very slow.

others - "make it look Processing-ish"&&me - "i didn't know Processing was a style"

You could create a virtual space and draw to that and save it. Then if you open up a small sized applet at the same time it will be very light on the machine.
Code:


PImage pic;
PGraphics3 gpic;
void setup(){
size(200,200,P3D);
pic = loadImage("11.gif");
gpic = new PGraphics3(100,100,null);
}
void draw(){
gpic.background(255);
gpic.rect(10,10,10,10);
image(gpic,0,0);
}
void mousePressed(){
pic.save("myPic.tif");
gpic.save("myGpic.tif");
}

PGraphics3 doesn't work however on 91 though. I just get a blue square.

I frequently use the large buffer method for generating larger than screen images, and then just blit bits of it to the display.

I guess there's no reason why a large buffer just couldn't be scaled to a small applet size as suggested above, as a kind of overview. Would probably slow things down, but could be a useful keypressed() {display thumbnail} type method.
