fa_png: Create a PNG version of a Font Awesome icon
Description
Get a Font Awesome icon as a PNG file. We can optionally set the fill
attribute before writing the PNG. Additionally, there is control over the
output width and height (usually, icons are 512 by 512 pixels). Please note
that this function requires that the rsvg is installed on the system.
Attempting to use fa_png() without rsvg available will result in an
error message.
the path to the output file. If NULL, then filename will take
the short name of the icon and a .png extension will be applied.
fill, fill_opacity
The fill color of the icon can be set with fill.
If not provided then the default fill color will be black. The opacity
level of the fill color can be controlled with a decimal value between 0
and 1.
stroke, stroke_width, stroke_opacity
The stroke options allow for
setting the color, width, and opacity of the outline stroke. By default,
the stroke width is very small at "1px" so a size adjustment with
"stroke_width" can be useful. The "stroke_opacity" value can be any
decimal values between 0 and 1 (bounds included).
height, width
The output height and width of the rendered PNG. If
nothing is provided then the output dimensions will match that of the input
SVG viewBox.
