--[[ EQUALIZER WIDGET
v1.0 by wlourf (10 Feb. 2010)
This widget draw a simple bar like (old) equalizers on hi-fi systems.
http://u-scripts.blogspot.com/ The arguments are :
- "name" is the type of stat to display; you can choose from 'cpu', 'memperc', 'fs_used_perc', 'battery_used_perc'.
- "arg" is the argument to the stat type, e.g. if in Conky you would write ${cpu cpu0}, 'cpu0' would be the argument.
If you would not use an argument in the Conky variable, use ''.
- "max" is the maximum value of the bar. If the Conky variable outputs a percentage, use 100.
- "nb_blocks" is the umber of block to draw
- "cap" id the cap of a block, possibles values are CAIRO_LINE_CAP_ROUND , CAIRO_LINE_CAP_SQUARE or CAIRO_LINE_CAP_BUTT
see
http://www.cairographics.org/samples/set_line_cap/ - "xb" and "yb" are the coordinates of the bottom left point of the bar
- "w" and "h" are the width and the height of a block (without caps)
- "space" is the space betwwen two blocks, can be null or negative
- "bgc" and "bga" are background colors and alpha when the block is not LIGHT OFF
- "fgc" and "fga" are foreground colors and alpha when the block is not LIGHT ON
- "alc" and "ala" are foreground colors and alpha when the block is not LIGHT ON and ALARM ON
- "alarm" is the value where blocks LIGHT ON are in a different color (values from 0 to 100)
- "led_effect" true or false : to show a block with a led effect
- "led_alpha" alpha of the center of the led (values from 0 to 1)
- "smooth" true or false : colors in the bar has a smooth effect
- "mid_color",mid_alpha" : colors of the center of the bar (mid_color can to be set to nil)
- "rotation" : angle of rotation of the bar (values are 0 to 360 degrees). 0 = vertical bar, 90 = horizontal bar
