Instance Method Summary

• #blit(src : Buffer, dst_x : Int32, dst_y : Int32, ignore_spaces : Bool = false) : Nil

  Blits (copies) another buffer onto this buffer at the given coordinates.

• #cells : Array(Cell)
• #clear : Nil
• #clone : Buffer
• #dim_all : Nil

  Dims the entire buffer to create a backdrop effect.

• #dim_rect(x : Int32, y : Int32, w : Int32, h : Int32) : Nil

  Applies dimming attribute to all cells within the given rectangle.

• #fill(x : Int32, y : Int32, w : Int32, h : Int32, cell : Cell = Cell.empty) : Nil
• #get(x : Int32, y : Int32) : Cell
• #height : Int32
• #in_bounds?(x : Int32, y : Int32) : Bool
• #put_char(x : Int32, y : Int32, char : Char, fg : Color = Color.none, bg : Color = Color.none, bold : Bool = false, dim : Bool = false, italic : Bool = false, underline : Bool = false, reverse : Bool = false) : Nil
• #put_string(x : Int32, y : Int32, text : String, fg : Color = Color.none, bg : Color = Color.none, bold : Bool = false, dim : Bool = false, italic : Bool = false, underline : Bool = false, reverse : Bool = false, max_width : Int32 | Nil = nil) : Int32
• #render_to_string(with_ansi : Bool = true) : String

  Renders the buffer content to a string, optionally including ANSI color and style sequences.

• #set(x : Int32, y : Int32, cell : Cell) : Nil
• #to_s(io : IO) : Nil

  Appends a short String representation of this object which includes its class name and its object address.

• #width : Int32
