Just make a big sketch surface. You can post-process the image with a good image viewer to change the DPI setting, if needed. You can also change the memory settings of Processing in its preferences dialog.

That could work but depends on what you render and what you need in the end. If you really need Highres Data about 10.000x12.000 pixels for example like i used to need when i do print stuff. This is probably a big loss in quality.

I was trying to decode the lines but I stuck at the very beginning of "import toxi.geom.*;"

I already download the unlekkerLib0003 library, but I don't know how to use this library.... Cry

I tried a bigger sketch surface, it didn't work, I need an image big enough to print in 36 * 42 inch size....

go back to the threat i mentioned. at the end of it toxi posted some code. you can simply use this code by pasting it into a new tab, or at the end of your sketch.
Seems like this code needs the toxiclib. Load the toxiclib core from here : http://code.google.com/p/toxiclibs/downloads/list
and install it. You isntall a librarie by extracting it to your libraries folder.
The libraries folder is a folder that has to be created when used the first time. It should be in your processing sketch folder.
You can find your sketch folder by looking at File->Preferences...

can you upload the pdf ? i will take a look and tell you why.

edit: ok i guess i know why, because you draw these lines by movint alot of ellipses, right? you probably used the pdf export that only exports a single frame. If you want to save everyframe with every ellipse you have to use an alternative way of exporting. It is described there too... but you probably get to many objects and opening the PDF becomes a problem... if it does, you should think about the HiRes Image again.
