# Fast GNOME thumbnailer for JPEG files that uses the embedded EXIF thumbnail
# from the source file, if present. Greatly speeds up thumbnail generation when
# browsing a folder of images shared over a network.
# Usage:
#   jpeg-exif-thumbnailer [size] [source] [destination]

set -e

# Transform the input file URI (for example, file://... or smb://...) into its
# locally mounted path.
input_path=$(gio info "$2" | grep "^local path:" | cut -d ' ' -f 3-)

# Use exiftool to extract the embedded preview image.
exiftool -a -b -W! "$3" -preview:all "$input_path"

if [ -s "$3" ]; then
	# If the extraction succeeded, convert the extracted image to the requested
	# format based on the requested file extension, and resize it to the
	# requested size. Since Nautilus requires PNG files, the mogrify command
	# is required even if -resize is not specified.
	mogrify -resize $1x$1 "$3"
	# If the extraction failed, fall back to the default system thumbnailer.
	/usr/bin/gdk-pixbuf-thumbnailer -s "$1" "$2" "$3"
