resize_to_standard: Resize an Image According to the Other Image or to Ratios
In plothelper: New Plots Based on 'ggplot2' and Functions to Create Regular Shapes

Simple wrapper of magick::image_resize. See the parameters below.

1	resize_to_standard(x, standard = 0.5, what = "all", scale = TRUE)

`x`	the image you want to resize.
`standard`	either the image whose size is the standard or two ratios. When it specifies two ratios, it should be a numeric vector whose first and second elements are multipliers for width and height. For example, x's width and height are 100 and 60, and `standard = c(0.5, 3)`, then the result image's width and height will be 50 and 180. If one of the two number is NA, then the dimension represented by this NA will be modified automatically.
`what`	this parameter is used only when `standard` is an image. It specifies the way to resize. When it is "width", let x's width be the same as `standard`; whether its height is automatically scaled depends on `scale`. When it is "height", let x's height be the same as `standard`; whether its width is automatically scaled depends on `scale`. When it is "all" (or "both"), the default, let x's width and height be the same as `standard`. When it is two number linked with a "_", it means resizing a according to b's width and height multiplied. For example, if it is "3_2" and b's width and height are 50, 70, then the result's width and height are 50 * 3 = 150, 70 * 2 = 140. Forms like "_2" or "3_" are also accepted.
`scale`	Default is TRUE. It is only used when only one of width and height is to be modified. This parameter decides whether the image is automatically scaled.
