# PNG to JPEG Converter for ComfyUI Output
# ===============================================================
#
# Purpose:
# This script converts PNG images generated by ComfyUI to JPEG format.
# It's designed to process images in the 'comfyui-output/dev-dancing' 
# directory and save the converted files in a './covers' directory.
#
# Features:
# - Converts PNG to JPEG using ImageMagick (magick convert)
# - Applies '-strip' to remove metadata and '-quality 90' for compression
# - Skips already converted images to allow for incremental processing
# - Creates the output directory if it doesn't exist
#
# Usage:
# ./convert_to_jpg.sh
#
# Note: Ensure ImageMagick is installed on your system before running.
#
# Author: [Your Name]
# Date: [Current Date]
# Version: 1.0
