- Background by londonali1010 (2009)
- This script draws a background to the Conky window. It covers the whole of the Conky window, but you can specify rounded corners, if you wish.
- To call this script in Conky, use (assuming you have saved this script to ~/scripts/):
- lua_load ~/.scripts/draw_bg.lua
- lua_draw_hook_pre draw_bg
- Changelog:
- + v1.0 -- Original release (07.10.2009)
- ]]
- -- Change these settings to affect your background.
- -- "corner_r" is the radius, in pixels, of the rounded corners. If you don't want rounded corners, use 0.
- corner_r=20
- -- Set the colour and transparency (alpha) of your background.
- bg_colour=0x4D4D4D
- bg_alpha=0.40
- require 'cairo'
- function rgb_to_r_g_b(colour,alpha)
- return ((colour / 0x10000) % 0x100) / 255., ((colour / 0x100) % 0x100) / 255., (colour % 0x100) / 255., alpha
