flextable (version 0.7.2)

save_as_image: save a flextable as an image

Description

save a flextable as a png, pdf or jpeg image.

Image generated with package 'webshot' or package 'webshot2'. Package 'webshot2' should be prefered as 'webshot' can have issues with some properties (i.e. bold are not rendered for some users).

The image is coming from a screenshot of the 'HTML' output. save_as_image() is a tool to make life easier for users. Nevertheless, the features have some limitations that can't be solved with flextable because they are not related to flextable:

• png does support transparency,

• jpeg does not support transparency,

• webshot2 does not allow transparent background,

• webshot does allow transparent background.

save_as_image(x, path, zoom = 3, expand = 10, webshot = "webshot")

Arguments

x

path

image file to be created. It should end with .png, .pdf, or .jpeg.
