\title{save a flextable as an image}
\usage{
save_as_image(x, path, zoom = 3, expand = 10, webshot = "webshot")
}
\arguments{
\item{x}{a flextable object}
\item{path}{image file to be created. It should end with .png, .pdf, or .jpeg.}
\item{zoom, expand}{parameters used by \code{webshot} function.}
\item{webshot}{webshot package as a scalar character, one of "webshot" or
"webshot2".}
}
\description{
save a flextable as a png, pdf or jpeg image.
Image generated with package 'webshot' or package 'webshot2'.
\strong{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.
\code{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:
\itemize{
\item \code{png} does support transparency,
\item \code{jpeg} does not support transparency,
\item webshot2 does not allow transparent background,
\item webshot does allow transparent background.
}
}
\note{
This function requires package webshot or webshot2.
The screenshot process is rather slow because it is managed by
an external program (see webshot or webshot2 documentation).
}
\examples{
ft <- flextable(head(mtcars))
ft <- autofit(ft)
tf <- tempfile(fileext = ".png")
\dontrun{
if (require("webshot")) {
save_as_image(x = ft, path = "myimage.png")
}
}
