time_slice.R requires the number of pixels wide or tall the image is to be a multiple of the number of images in your timelapse.
time_slice_v2.R attempts to get around this. Some images will contribute more pixels per slice than others. This is done by making the first
x% of the images cover the first
x% of the pixels (with appropriate rounding). It does not deal with number of images being greater than the height or width of the images in pixels. Version 2 will probably work better for you.
For example, if the images are 150 pixels wide and your timelapse has 100 images,
time_slice.R will make the first image have a slice which is 51 pixels wide. The remaining 99 images will get slices which are 1 pixel wide.
time_slice_v2.R will alternate between 1 pixel per image and 2 pixels per image. All of the odd numbered images will get 1 pixel and all of the even numbered images will get 2 pixels. I haven't tested it out enough to tell if this causes any weird undesired (or desired) effects.
Time Slice Lapse
time_slice_lapse.R creates a time lapse out of time slices. (It actually creates the images necessary to create a time lapse. You still have to combine them into a movie.)
There are five options. As before, you can choose the
direction. Then I split the path into
source_path is where the original images are saved. The
save_path is where you want to save the time_slices, which will be used to create a time lapse.
The two new options are
images_per_slice controls how many images make up each slice and
num_of_slices controls how many slices will be in the time lapse. You probably want to use the default for the
num_of_slices (i.e. use all of the available images). For
images_per_slice, you can probably get different results based on this. The larger this is, the more time passes with a slice, but the fewer available slices for a time lapse. images_per_slice must be less than the number of pixels wide or tall.
I tried it out on a small example and it seems to work. I used only 10
images_per_slice which resulted in 36 total slices. It is posted here.
