We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Not sure if the title describes this properly. I want to take say 100 images and extract a single row of pixels from each image and then reconstitute the images.
load initialPix1-100
get row 1 from each image and make finalpix_one from these rows
get row 2 from each image and make finalpix_two from these rows
get row 3 from each image and make finalpix_three from these rows
##########
void setup(){
size(400,400);
img_one = loadImage("initial_one.jpg");
img_two = loadImage("initial_two.jpg");
img_three = loadImage("initial_three.jpg");
finalpix_one.set(0,0, initial_one.get(0,1,initial_one.width,1) );
finalpix_one.set(0,1, initial_two.get(0,1,initial_two.width,1) );
finalpix_one.set(0,2, initial_three.get(0,1,initial_three.width,1) );
finalpix_two.set(0,0, initial_one.get(0,2,initial_one.width,1) );
finalpix_two.set(0,1, initial_two.get(0,2,initial_two.width,1) );
finalpix_two.set(0,2, initial_three.get(0,2,initial_three.width,1) );
finalpix_three.set(0,0, initial_one.get(0,3,initial_one.width,1) );
finalpix_three.set(0,1, initial_two.get(0,3,initial_two.width,1) );
finalpix_three.set(0,2, initial_three.get(0,3,initial_three.width,1) );
My question is -- does this make sense or would it be easier to do this with pixels[] can anyone see an easy way to pick if this works with taking 2 rows at a time rather than a single row? If I keep spitting out to the final pix will it overwrite it or append like I want-- there has to be a way to do this that I am not seeing.

You want to do a same task with lots of pictures, so you need an algorithm to do it. First, have an array of images:
PImage[] images = new PImage[numImages];
, if you rename all your pictures to be 0.jpg, 1.jpg, 2.jpg and so on, you can load them with a loop:now, you can loop through all of the images and extract needed row, fortunately, each row of pixels corresponds with the number of picture!
This is untested, but you get an idea, and I hope can debug if it does not work.
Also mind that it is assumed that all pictures have the same size.
