unigd (version 0.2.0)

ugd_save: Render unigd plot to a file.

Description

See ugd_render() for accessing plot data directly in memory without saving as a file. This function will only work after starting a device with ugd().

Usage

ugd_save(
  file,
  page = 0,
  width = -1,
  height = -1,
  zoom = 1,
  as = "auto",
  which = dev.cur()
)

Value

No return value. Plot will be saved to file.

Arguments

file

Filepath to save plot.

page

Plot page to render. If this is set to 0, the last page will be selected. Can be set to a numeric plot index or plot ID (see ugd_id()).

width

Width of the plot. If this is set to -1, the last width will be selected.

height

Height of the plot. If this is set to -1, the last height will be selected.

zoom

Zoom level. (For example: 2 corresponds to 200%, 0.5 would be 50%.)

as

Renderer. When set to "auto" renderer is inferred from the file extension.

which

Which device (ID).

Examples

ugd()

plot(1, 1)

tf <- tempfile()
on.exit(unlink(tf))

ugd_save(file = tf, width = 600, height = 400, as = "png")

dev.off()
