Using arrays in a save function?

in Programming Questions • 1 year ago

Hi --

I'm loading data in from a dataset, parsing it, and saving each variable into an array. I then would like to loop through the data, drawing each observation, and saving the resulting image. Unfortunately I can't seem to be able to call an array in the save() function -- the filename has to be entirely in quotes. Any thoughts?

Thanks!

Matt

Looks like you misunderstood the purpose of the parameter in save(). It is a file name, not data. To save the content of an array of strings, use saveStrings(). If you want to save an image, use save() as function (saving the sketch) or as method of a PImage.

I understand that the parameter in save() is a file name, but I'm wondering if the file name can be specified by the data in my array. Specifically, I'm looping the program through many observations of data and would like to save the image created by each observation as it runs through the program.

Well, you already do a loop, so call save() on each iteration to save the corresponding image. You can use nf() to include a formatted number in the file name.
