# Must be run on an Amazon Linux AMI that matches AWS Lambda's runtime which can be found at:
# https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html
#
# As of Jan 10, 2019, this is:
# Amazon Linux AMI 2017.03.1.20170812 x86_64 HVM GP2 (ami-4fffc834)
#
# Lambda includes ImageMagick 6.7.8-9 preinstalled, so you need to prepend PATH
# with the folder containing these binaries in your Lambda function to ensure
# these newer binaries are used.
#
# In a NodeJS runtime, you would add something like the following to the top of
# your Lambda function file:
# process.env['PATH'] = process.env['LAMBDA_TASK_ROOT'] + '/imagemagick/bin:' + process.env['PATH']
