Description

Writes the hillshaded map to file.

Usage

save_png(
  hillshade,
  filename,
  title_text = NA,
  title_offset = c(20, 20),
  title_color = "black",
  title_size = 30,
  title_font = "sans",
  title_style = "normal",
  title_bar_color = NULL,
  title_bar_alpha = 0.5,
  title_position = "northwest",
  rotate = 0,
  asp = 1
)

Arguments

hillshade	Array (or matrix) of hillshade to be written.
filename	String with the filename. If '.png' is not at the end of the string, it will be appended automatically.
title_text	Default 'NULL'. Text. Adds a title to the image, using 'magick::image_annotate()'.
title_offset	Default 'c(20,20)'. Distance from the top-left (default, 'gravity' direction in image_annotate) corner to offset the title.
title_color	Default 'black'. Font color.
title_size	Default '30'. Font size in pixels.
title_font	Default 'sans'. String with font family such as "sans", "mono", "serif", "Times", "Helvetica", "Trebuchet", "Georgia", "Palatino" or "Comic Sans".
title_style	Default 'normal'. Font style (e.g. 'italic').
title_bar_color	Default 'NULL'. If a color, this will create a colored bar under the title.
title_bar_alpha	Default '0.5'. Transparency of the title bar.
title_position	Default 'northwest'. Position of the title.
rotate	Default 0. Rotates the output. Possible values: 0, 90, 180, 270.
asp	Default '1'. Aspect ratio of the resulting plot. Use 'asp = 1/cospi(mean_latitude/180)' to rescale lat/long at higher latitudes to the correct the aspect ratio.

Examples

filename_map = tempfile()

#Save the map into `filename_map`
montereybay %>%
 sphere_shade() %>%
 save_png(filename_map)
 
#Rotate the map 180 degrees:

montereybay %>%
 sphere_shade() %>%
 save_png(filename_map,rotate=180)
