Description

Utilities for manipulating [[Bool]] as images

Synopsis

data Placement
- = OffsetLeft Int Int
- | OffsetRight Int Int
- | CenterLeft Int
- | CenterRight Int
iconPosition :: Rectangle -> Placement -> [[Bool]] -> (Position, Position)
drawIcon :: (Functor m, MonadIO m) => Display -> Drawable -> GC -> String -> String -> Position -> Position -> [[Bool]] -> m ()

Usage:

This module uses matrices of boolean values as images. When drawing them, a True value tells that we want the fore color, and a False value that we want the background color to be painted. In the module we suppose that those matrices are represented as [[Bool]], so the lengths of the inner lists must be the same.

See XMonad.Layout.Decoration for usage examples

data Placement Source #

Placement of the icon in the title bar

Constructors

OffsetLeft Int Int	An exact amount of pixels from the upper left corner
OffsetRight Int Int	An exact amount of pixels from the right left corner
CenterLeft Int	Centered in the y-axis, an amount of pixels from the left
CenterRight Int	Centered in the y-axis, an amount of pixels from the right
