# USAGE: transitions [-m mode] [-f frames] [-d delay] [-p pause] [-r] [-e] infile1 infile2 maskfile [outfile]
# USAGE: transitions [-h or -help]
#
# OPTIONS:
#
# -m      mode           mode of transition; wipe or dissolve; default=wipe
# -f      frames         number of frames in animation; frames>1; default=20
# -d      delay          delay between frames; delay>0; default=20
# -p      pause          pause delay for two undistorted input images;
#                        pause>0; default=50
# -r                     reverse the animation sequence and append it to the end
# -e                     exponentiate maskfile to make the animation
#                        start more gradually. Mostly useful for mode=dissolve
#
# The two input files and mask file must be the same size.
#
# The output file must be of type that supports multi-frames, such as gif.
#
# If no output file is specified, the animation will be displayed automatically
# but not saved to a file
#
###
#
# NAME: TRANSITIONS
#
# PURPOSE: To apply an animated transition between two images.
#
# DESCRIPTION: TRANSITIONS applies an animated transition between two images
# using a mask image to control the transition. The first image will show
# where the mask is black and the second image will show where the mask is
# white. The mask will be made gradually more an more white as each frame
# is composited. NOTE that this is not a true warping morph. It is simply
# an animated masked composite.
#
# OPTIONS:
#
# -m mode ... MODE of transition. Values are wipe or dissolve. The default is wipe.
# Note that dissolve is generally only useful for very gradual graylevel changes
# in the mask image, such as a linear or radial gradient.
#
# -f frames ... FRAMES is the total number of frames in the animation (including
# infile1 and infile2 as the start and end frames. Values are integers > 1. The
# default is 20.
#
# -d delay ... DELAY between frames. Values are integers>0. The default=20
#
# -p pause ... PAUSE is the delay to use for the first and last frame of the
# animation, i.e. the delay for each of the input images. The default=50
#
# -r ... If supplied, then reverse the animation sequence, remove the first and
# last frames of the reversed sequence and append these reversed frames to
# the end of the animation.
#
# -e ... If supplied, then the maskfile will be exponentiated to make the
# animation start more gradually. This is useful for most dissolve mode
# transitions.
#
# CAVEAT: No guarantee that this script will work on all platforms,
# nor that trapping of inconsistent parameters is complete and
# foolproof. Use At Your Own Risk.

"""Simple command-line tool to autoenhance photos via Google+.

To run this sample you will need the Google APIs Client Library for Python
Installation instructions here:
https://developers.google.com/api-client-library/python/start/installation

You will also need to set up a project in the APIs Console (or Cloud console)
https://code.google.com/apis/console or https://cloud.google.com/console
and create credentials for an "Installed applications".
You can then download a client_secrets.json and place it in the same folder

	# DESCRIPTION: TRANSITIONS applies an animated transition between two images
	# using a mask image to control the transition. The first image will show
	# where the mask is black and the second image will show where the mask is
	# white. The mask will be made gradually more an more white as each frame
	# is composited. NOTE that this is not a true warping morph. It is simply
	# an animated masked composite.
	#
	# OPTIONS:
	#
	# -m mode ... MODE of transition. Values are wipe or dissolve. The default is wipe.
	# Note that dissolve is generally only useful for very gradual graylevel changes
	# in the mask image, such as a linear or radial gradient.
	#
	# -f frames ... FRAMES is the total number of frames in the animation (including
	# infile1 and infile2 as the start and end frames. Values are integers > 1. The
	# default is 20.
	#
	# -d delay ... DELAY between frames. Values are integers>0. The default=20
	#
	# -p pause ... PAUSE is the delay to use for the first and last frame of the
	# animation, i.e. the delay for each of the input images. The default=50
	#
	# -r ... If supplied, then reverse the animation sequence, remove the first and
	# last frames of the reversed sequence and append these reversed frames to
	# the end of the animation.
	#
	# -e ... If supplied, then the maskfile will be exponentiated to make the
	# animation start more gradually. This is useful for most dissolve mode
	# transitions.
	#
	# CAVEAT: No guarantee that this script will work on all platforms,
	# nor that trapping of inconsistent parameters is complete and
	# foolproof. Use At Your Own Risk.

	"""Simple command-line tool to autoenhance photos via Google+.

	To run this sample you will need the Google APIs Client Library for Python
	Installation instructions here:
	https://developers.google.com/api-client-library/python/start/installation

	You will also need to set up a project in the APIs Console (or Cloud console)
	https://code.google.com/apis/console or https://cloud.google.com/console
	and create credentials for an "Installed applications".
	You can then download a client_secrets.json and place it in the same folder
