Store memory of int change after processing exits

in Programming Questions • 11 months ago

Hey all

I'm currently running a piece of work for a show which needs to run for 6 minutes, take a screengrab, exit the program and restart.. I've currently achieved this using a separate program to start the processing app, then exit the program within processing..

I'm having difficulty archiving my screengrabs..

The code thats produced the best results so far is very basic.. however it potentially overwrites previously existing images and is not chronological.

{

if (millis()>=350000) {

saveFrame("data/portrait-######.bmp");

exit();

}

i've experimented with archiving in numeric order using a string, however i'm not sure how to create a memory of the current value of the image. My screengrabs overwrite each-other.

int number = 0;

void draw()

{

if (millis()>= 350000) {

{

String s = "data/portrait" + nf(number,4) +".bmp";

save(s);

number++;

}

Any suggestions on ways to create a memory of the 'number' integer?

Cheers!

Save it to a text file at the end.
Load it from a text file at the beginning.

Alternatively, you can use a timestamp down to the millisecond: a nice side effect is that you know when the image has been saved.
DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd--HH-mm-ss-SSS");
OR
DateFormat formatter = new SimpleDateFormat("yyyyMMdd-HHmmss-SSS"); // Or other combinations

Date d = new Date(); // Current date
println(formatter.format(d)); // Use the result in the file name
