Chops up an image so that it may be used for scrolling image videos. Not very sophisticated.

imagechop.py

from PIL import Image
#what image?
im = Image.open("./xgCGa.jpg")
outdir = "./output/"

#define time to match
time = 177.0
frametime = .03

#define size of image
size_x = im.size[0]
size_y = im.size[1]

#define stepsize
total_frames = time / frametime
stepsize = (float(size_y) - float(size_x)) / total_frames
steps = []
val = 0
while val < (size_y - size_x):
    steps.append(val)
	val += stepsize

#go through steps of the image
a = 0
for val in steps:
    step = int(val)
    stepim = im.crop((0, step, size_x, step + size_x))
    stepim.save(outdir + "frame" + str(a) + ".jpg", "JPEG")
    a += 1
