# Script Name: collect-wallpapers.sh
|
|
#
|
|
# Description:
|
|
# Scans a directory tree for image files and prepares them for wallpaper use.
|
|
#
|
|
# The script:
|
|
# 1. Searches recursively for JPG, JPEG, and PNG images.
|
|
# 2. Renames files by replacing spaces with underscores.
|
|
# 3. Converts JPG/JPEG images to PNG format.
|
|
# 4. Calculates image aspect ratio and width.
|
|
# 5. Identifies images matching a target screen aspect ratio.
|
|
# 6. Optionally copies matching images to a wallpaper collection folder.
|
|
#
|
|
# Matching Criteria:
|
|
# - Aspect ratio close to 16:9 portrait (0.5625)
|
|
# - Configurable tolerance range
|
|
# - Minimum image width requirement
|
|
#
|
|
# Requirements:
|
|
# - Bash
|
|
# - ImageMagick (identify, convert)
|
|
# - bc
|
|
#
|
|
# Usage:
|
|
#
|
|
# Scan only:
|
|
# ./collect-wallpapers.sh <image_directory>
|
|
#
|
|
# Scan and copy matching images:
|
|
# ./collect-wallpapers.sh <image_directory> -m
|
|
#
|
|
# Examples:
|
|
#
|
|
# Analyze images:
|
|
# ./collect-wallpapers.sh ~/Pictures
|
|
#
|
|
# Collect wallpaper candidates:
|
|
# ./collect-wallpapers.sh ~/Pictures -m
|
|
#
|
|
# Output:
|
|
# Matching files are copied to:
|
|
#
|
|
# /data/Ubuntu_Data/Videos/.stuff/
|
|
#
|
|
# Notes:
|
|
# - JPG/JPEG files are converted to PNG.
|
|
# - Spaces in filenames are replaced with underscores.
|
|
# - Original PNG files remain unchanged.
|
|
# - Original JPG/JPEG files are removed after conversion.
