data AreaDimensions Source #
Height and width of a 2D map region
upperLeftToBottomRight :: AreaDimensions -> Location -> Location Source #
Incorporates an offset by -1
, since the area is
"inclusive" of the lower-right coordinate.
Inverse of cornersToArea
.
cornersToArea :: Location -> Location -> AreaDimensions Source #
Converts the displacement vector between the two
diagonal corners of the rectangle into an AreaDimensions
record.
Adds one to both dimensions since the corner coordinates are "inclusive".
Inverse of upperLeftToBottomRight
.
isEmpty :: AreaDimensions -> Bool Source #
Has zero width or height.
getAreaDimensions :: [[a]] -> AreaDimensions Source #
Extracts the dimensions of a map grid.
