Coerce to bitmap list objects

Source: R/as_bm_list.R
as_bm_list.Rd

as_bm_list() turns an existing object into a bm_list() object. In particular as_bm_list.character() turns a string into a bitmap list.

Usage

as_bm_list(x, ...)

# Default S3 method
as_bm_list(x, ...)

# S3 method for class 'bm_list'
as_bm_list(x, ...)

# S3 method for class 'list'
as_bm_list(x, ..., FUN = identity)

# S3 method for class 'character'
as_bm_list(x, ..., font = bm_font())

Arguments

x

An object that can reasonably be coerced to a bm_list() object.

...

Further arguments passed to or from other methods.

FUN

Function to apply to every element of a list such as as_bm_bitmap() or as_bm_pixmap().

font

A bm_font() object that contains all the characters within x.

Value

A bm_list() object.

Examples

  # as_bm_list.character()
  font_file <- system.file("fonts/spleen/spleen-8x16.hex.gz", package = "bittermelon")
  font <- read_hex(font_file)
  bml <- as_bm_list("RSTATS", font = font)
  bml <- bm_extend(bml, sides = 1L, value = 0L)
  bml <- bm_extend(bml, sides = c(2L, 1L), value = 2L)
  bm <- do.call(cbind, bml)
  print(bm, px = c(" ", "#", "X"))
