Dep.Bricks.Layered

Contents

A type synoniem for one layer.
Merge several layers to one layer.

Description

This module exports the mergeLayers function that combine multiple Layers in a single layer. This is used if writing several layers is easier than writing a single image.

Synopsis

type Layer a = [[a]]
createImage :: [[(Attr, Char)]] -> Image
mergeLayers :: (Char -> Bool) -> [(Attr, Layer Char)] -> Image

A type synoniem for one layer.

type Layer a = [[a]] Source #

A raster is a list of lists of characters.

Merge several layers to one layer.

createImage Source #

Arguments

:: [[(Attr, Char)]]	The given list of lists of `Char`s
-> Image

Convert a list of lists of 2-tuples that contain an Attributes and a Char to an Image.

mergeLayers Source #

Arguments

:: (Char -> Bool)	The predicate that determines if the upper layer will override the layer directly below.
-> [(Attr, Layer Char)]	The list of `Layer`s, the first item is the top item and the last item is the bottom layer.
-> Image	An image that we create by merging the different layers together.

Merge the given Layers with the corresponding Attributes to a single Image.
