Convert a tRNA structure SVG to PNG — structure_to_png • clover

Renders an SVG file (typically produced by plot_tRNA_structure()) to a PNG bitmap. Requires the rsvg package.

Usage

structure_to_png(svg_path, output = NULL, width = NULL, height = NULL)

Arguments

svg_path: Path to an SVG file, typically the return value of plot_tRNA_structure().
output: Path for the output PNG file. If NULL (default), replaces the .svg extension with .png.
width: Width of the output PNG in pixels. If NULL (default), uses the intrinsic SVG width.
height: Height of the output PNG in pixels. If NULL (default), uses the intrinsic SVG height.

Value

The path to the PNG file (invisibly).

Examples

# \donttest{
svg <- plot_tRNA_structure("tRNA-Glu-TTC", "Escherichia coli")
structure_to_png(svg)
# }
