rsvg {rsvg} | R Documentation |
Render svg image into a high quality bitmap. When both width
and height
are NULL
, the output resolution matches that of the input. When either width
or height
is specified, the image is scaled proportionally. When both width
and height
are specified, the image is stretched into the requested size.
rsvg(svg, width = NULL, height = NULL) rsvg_raw(svg, width = NULL, height = NULL) rsvg_webp(svg, file = NULL, width = NULL, height = NULL) rsvg_png(svg, file = NULL, width = NULL, height = NULL) rsvg_pdf(svg, file = NULL, width = NULL, height = NULL) rsvg_svg(svg, file = NULL, width = NULL, height = NULL) rsvg_ps(svg, file = NULL, width = NULL, height = NULL)
