#
#
# This little script uses convert from ImageMagick to generate CUPS buttons.
# It requires ImageMagick version 6.2.4 or higher.
#
# It can generate 20-pixel high one-line buttons and 40-pixel high two-line
# buttons.
#
# Usage:
#
# tools/makebuttons [--font filename] locale buttons.txt
#
# "Locale" is the locale name, either "ll" or "ll_CC" where "ll" is the
# 2-letter language abbreviation and "CC" is the 2-letter ISO country
# code. The new "ll-region" syntax is *not* supported at this time
# and should not be used!
#
# "Buttons.txt" is a file containing the buttons to be created and must
# be formatted as follows:
#
# filename.gif color text for button
#
# "filename.gif" is the name of the image file to create.
#
# "color" is the color of the button, one of "std" (the normal olive
# background), "black", "green", or "red".
#
# The remainder of the line following the color is used as the text
# for the button. Use "@UP" and "@DOWN" to include up and down arrows,
# and "\\n" to break the text into 2 lines (not generally recommended).
#
# Lines starting with '#' are treated as comments. See the file
# "tools/buttons.txt" for inspiration...
