Description

cbind.bm_bitmap() / cbind.bm_pixmap() and rbind.bm_bitmap() / rbind.bm_pixmap() combine by columns or rows respectively.

Usage

# S3 method for bm_bitmap
cbind(..., direction = "left-to-right", vjust = "center-top")
# S3 method for bm_bitmap
rbind(..., direction = "top-to-bottom", hjust = "center-left")
# S3 method for bm_pixmap
cbind(..., direction = "left-to-right", vjust = "center-top")
# S3 method for bm_pixmap
rbind(..., direction = "top-to-bottom", hjust = "center-left")

Value

A bm_bitmap() or bm_pixmap() object.

Arguments

...

bm_bitmap() or bm_pixmap() objects.

direction

For cbind() either "left-to-right" (default) or its aliases "ltr" and "lr" OR "right-to-left" or its aliases "rtl" and "rl". For rbind() either "top-to-bottom" (default) or its aliases "ttb" and "tb" OR "bottom-to-top" or its aliases "btt" and "bt". The direction argument is not case-sensitive.

vjust

Used by bm_extend() if bitmap heights are different.

hjust

Used by bm_extend() if bitmap widths are different.

Examples

  font_file <- system.file("fonts/spleen/spleen-8x16.hex.gz", package = "bittermelon")
  font <- read_hex(font_file)
  capital_b <- font[[str2ucp("B")]]
  capital_m <- font[[str2ucp("M")]]
  cbm <- cbind(capital_b, capital_m)
  print(cbm)
  cbm_rl <- cbind(capital_b, capital_m, direction = "right-to-left")
  print(cbm_rl)
  rbm <- rbind(capital_b, capital_m)
  print(rbm)
  rbm_bt <- rbind(capital_b, capital_m, direction = "bottom-to-top")
  print(rbm_bt)
