## S3 method for class 'nativeRaster'
bm_expand(x, width = 1L, height = width)

## S3 method for class 'raster'
bm_expand(x, width = 1L, height = width)

Arguments

x	Either a bm_bitmap(), bm_font(), bm_list(), "magick-image", "nativeRaster", bm_pixmap(), or "raster" object.
width	An integer of how many times to repeat each column.
height	An integer of how many times to repeat each row.
...	Additional arguments to be passed to or from methods.

Value

Depending on x either a bm_bitmap(), bm_font(), bm_list(), magick-image, "nativeRaster", bm_pixmap(), or raster object.

Examples

 font_file <- system.file("fonts/spleen/spleen-8x16.hex.gz", package = "bittermelon")
 font <- read_hex(font_file)
 capital_r <- font[[str2ucp("R")]]
 print(capital_r)
 print(bm_expand(capital_r, 2L),
       px = px_ascii)
 print(bm_expand(capital_r, width = 1L, height = 2L),
       px = px_ascii)
 print(bm_expand(capital_r, width = 2L, height = 1L),
       px = px_ascii)
