processing - What is the filename of last saved frame using saveFrame() -

in processing, can save frame using saveframe('output-####.png'). save frame, name output-0001.png, , place in sketch folder. filename different because follows sequence, replacing #### next number in sequence.

however, saveframe returns void. wish returned string of filename, doesn't.

how can find out name of frame saved saveframe(...)

you can wrap function tell framecount @ point:

void draw() {   println(saveframeandgetfilename("output-####.png")); } string saveframeandgetfilename(string filename) {   saveframe(filename);   string [] parts = filename.split("####"); //getting pedantic here...   return parts[0] + framecount + parts[1]; } 

or more simply:

void draw() {   saveframe("output-####.png");   println("output-" + framecount + ".png"); } 

edit: fixed give actual filename
