Image chunk wrapper

Source: R/chunk_images.R

The function lets add images within flextable objects with functions:

as_image(src, width = NULL, height = NULL, unit = "in", guess_size = TRUE, ...)

Arguments

src

image filename

width, height

size of the image file. It can be ignored if parameter guess_size=TRUE, see parameter guess_size.

unit

unit for width and height, one of "in", "cm", "mm".

guess_size

If package 'magick' is installed, this option can be used (set it to TRUE and don't provide values for paramters width and height). When the flextable will be printed, the images will be read and width and height will be guessed. This should be avoid if possible as it can be an extensive task when several images.

...

unused argument

Note

This chunk option requires package officedown in a R Markdown context with Word output format.

PowerPoint cannot mix images and text in a paragraph, images are removed when outputing to PowerPoint format.
