Calculate the maximum and minimum x and y coordinates across the stimuli (or for each stimulus) and crop all image to this plus padding.
Usage
crop_tem(
stimuli,
top = 10,
right = top,
bottom = top,
left = right,
each = FALSE,
...
)
Arguments
- stimuli
list of stimuli
- top, right, bottom, left
numeric; number of pixels or proportion (<1) to pad each side
- each
logical; Whether to calculate bounds for the full set (default) or each image separately
- ...
