Widths or heights of bitmaps

Description

bm_widths() returns the widths of the bitmaps while bm_heights() returns the heights of the bitmaps. bm_widths() and bm_heights() are S3 generic functions.

Usage

bm_heights(x, ...)

## S3 method for class 'bm_matrix'
bm_heights(x, ...)

## S3 method for class 'bm_list'
bm_heights(x, unique = TRUE, ...)

## S3 method for class ''magick-image''
bm_heights(x, ...)

## S3 method for class 'nativeRaster'
bm_heights(x, ...)

## S3 method for class 'raster'
bm_heights(x, ...)

bm_widths(x, ...)

## S3 method for class 'bm_matrix'
bm_widths(x, ...)

## S3 method for class 'bm_list'
bm_widths(x, unique = TRUE, ...)

## S3 method for class ''magick-image''
bm_widths(x, ...)

## S3 method for class 'nativeRaster'
bm_widths(x, ...)

## S3 method for class 'raster'
bm_widths(x, ...)

Arguments

x	Either a bm_bitmap(), bm_font(), bm_list(), "magick-image", "nativeRaster", bm_pixmap(), or "raster" object.
...	Ignored.
unique	Apply base::unique() to the returned integer vector.

Value

A integer vector of the relevant length of each of the bitmap objects in x. If unique is TRUE then any duplicates will have been removed.

Examples

font_file <- system.file("fonts/spleen/spleen-8x16.hex.gz", package = "bittermelon")
font <- read_hex(font_file)
bm_widths(font) # every glyph in the font is 8 pixels wide
bm_heights(font) # every glyph in the font is 16 pixels high
corn <- farming_crops_16x16()$corn$portrait
bm_widths(corn)
bm_heights(corn)
