The opacity value is a number from 0 to 1, with zero being fully transparent and 1 being fully opaque. If no opacity argument is given, a default value of 0.75 is used for the opacity value. If neither --inc nor --dec are given, the opacity is treated as an absolute value and set to the given opacity value. If --inc or --dec is specified, then the opacity is treated as a relative value to increase or decrease the current opacity by.
8 -display display This option specifies the server to use; see X(__miscmansuffix__).
8 -h ", " --help This option displays a help message and exits.
8 -t ", " --toggle This option forces a toggle of opacity. If the current opacity is not set to fully opaque (opacity 1.0), it will be reset to fully opaque. If the window is already fully opaque, the opacity will be set normally.
8 -c ", " --click This option selects the target window by waiting for the user to click the mouse - the topmost window under the mouse cursor when the mouse click occurs will be used as the target.
8 -p ", " --point This option selects the window currently under the cursor to be the target.
8 -a ", " --actual This option selects the window that currently has input focus to be the target.
8 -n ", " --name " name" This option selects the target window by name, where name is matched as a regular expression, unless --no-regex is also specified.
8 --no-regex This option disables treating the name argument to --name as a regular expression.
8 -i ", " --id This option selects the target window by window id.
8 --inc This option increases the window opacity by the given opacity argument.
8 --dec This option decreases the window opacity by the given opacity argument.
8 -m ", " --min " opacity" This option sets the minimum possible opacity value. It defaults to 0 if this option is not given.
8 -x ", " --max " opacity" This option sets the maximum possible opacity value. It defaults to 1 if this option is not given.
8 -v ", " --verbose This option prints some additional debug info as the program operates.
8 -V ", " --version This option prints the program version number and exits.
