"""
Add files to your project from a directory, can look recursively.
Specify in- or exclude arguments, filetypes, duplicate-action and copy
or link raw files to save memory on the harddrive. For each found image,
a folder will be created in the "data" folder within the projects root
directory. If found images are in subfolders and search_mode is
recursive, the respective phenopype directories will be created with
flattened path as prefix.
E.g., with "raw_files" as folder with the original image files
and "phenopype_proj" as rootfolder:
- raw_files/file.jpg ==> phenopype_proj/data/file.jpg
- raw_files/subdir1/file.jpg ==> phenopype_proj/data/1__subdir1__file.jpg
- raw_files/subdir1/subdir2/file.jpg ==> phenopype_proj/data/2__subdir1__subdir2__file.jpg
Parameters
----------
image_dir: str
path to directory with images
filetypes: list or str, optional
single or multiple string patterns to target files with certain endings.
"default_filetypes" are configured in settings.py
include: list or str, optional
single or multiple string patterns to target certain files to include
exclude: list or str, optional
single or multiple string patterns to target certain files to exclude -
can overrule "include"
raw_mode: {"copy", "link"} str, optional
how should the raw files be passed on to the phenopype directory tree:
"copy" will make a copy of the original file, "link" will only send the
link to the original raw file to attributes, but not copy the actual
file (useful for big files)
search_mode: {"dir", "recursive"}, str, optional
"dir" searches current directory for valid files; "recursive" walks
through all subdirectories
unique_mode: {"filepath", "filename"}, str, optional:
how to deal with image duplicates - "filepath" is useful if identically
named files exist in different subfolders (folder structure will be
collapsed and goes into the filename), whereas filename will ignore
all similar named files after their first occurrence.
