because "base64" could conceivably appear within the data string. Also implemented -u, --uri_only option.

# png2uri is a command-line application that creates an HTML "img" tag on
|
|
# standard output containing a data URI in accordance with RFC-2397, from
|
|
# a PNG file or from a PNG datastream received from standard input.
|
|
#
|
|
# Usage: png2uri [-u|--uri_only] [file]
|
|
#
|
|
# options: -u|--uri_only|--url_only: omit the surrounding "img" tag
|
|
# and only write the data URI.
|
|
#
|
|
# Requires /bin/sh and a uuencode(1) that takes the "-m" option to mean
|
|
# to encode in base64 according to RFC-3548.
|
|
#
|
|
# If you prefer a web-based converter or a java application, this isn't
|
|
# it. Use your search engine and look for "png data uri" to find one.
