c19_inkmagick: Produce high-quality PNG & JPEG (along with SVG).

In StanTraykov/c19bg: COVID-19 Charts for Bulgaria

Description

Production quality output using Inkscape for rasterization & ImageMagick for JPEG compression. (SVG output is the same quality as other functions.)

Usage

c19_inkmagick(
  var = TRUE,
  eu = TRUE,
  r = TRUE,
  d_all = FALSE,
  dl = TRUE,
  rl = TRUE
)

Arguments

var	whether to output various data.egov.bg-sourced plots
eu	whether to output EUROSTAT/ECDC-sourced plots
r	whether to plot r (incl. time-consuming calculation)
d_all	whether to plot age band death plots for countries other than BG
dl	whether to refresh all data sets from the Internet
rl	whether to refresh all data sets from disk

Details

Using these programs yields slightly better results but is not really necessary. c19_save_all() saves SVG of the same quality but produces lower-quality PNG/JPEG. You can also save individual plots using ggplot2::ggsave() or plot to screen (e.g. c19_heat() or print(c19_heat()) in non-interactive mode).

Output files will be stored in folders c19bg/plots/MMMDD (month-day). Downloaded and calculated data will be stored in c19bg/data.

Paths to Inkscape and ImageMagick can be set via options.
