First the grViz
object is exported to an SVG file (using DiagrammeRsvg::export_svg
).
Then the SVG file is converted to a bitmap (using rsvg::rsvg
).
Then the bitmap is exported as a PNG file (using png::writePNG
).
Note that the SVG file and the PNG file will be named using the name of the g
parameter
