bm_expand: Expand bitmaps by repeating each row and/or column

Description

bm_expand() expands bitmap(s) by repeating each row and/or column an indicated number of times.

Usage

bm_expand(x, width = 1L, height = width)
# S3 method for bm_bitmap
bm_expand(x, width = 1L, height = width)
# S3 method for bm_list
bm_expand(x, ...)
# S3 method for bm_pixmap
bm_expand(x, width = 1L, height = width)
# S3 method for `magick-image`
bm_expand(x, width = 1L, height = width)
# S3 method for nativeRaster
bm_expand(x, width = 1L, height = width)
# S3 method for raster
bm_expand(x, width = 1L, height = width)

Value

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

Arguments

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.
