Exporting Data??? (Read 1036 times)

jknox YaBB Newbies Offline Posts: 8	Exporting Data??? Feb 3^rd, 2010, 7:30pm I have a script that has two loops in void draw(). as it goes through each time it exports a different jpeg image. (25) I was wondering if there is a command that allows me to also export the data or code that made the image. It would be beneficial to be able to retrieve the exact floats and integers that created that specific image. thanks

yes, you can save txt files and save all kind of information in it.
take a look at http://processing.org/reference/createWriter_.html

but maybe it would be enough in your case to write all the information to the name of the image. that would make it easy to read the data.
so instead of just saveFrame("image.tif");
you could write
saveFrame(x+"-"+y"-"+size+"-"+count".tif");

this would save images named 30-40-100-0001.tif for example..
Hope that makes sense
