Description

Raster Animation

Usage

raster_animation(
  rasters,
  filename,
  bbox,
  outdir,
  framerate = 4,
  width = 7,
  height,
  dpi = 100
)

Arguments

rasters	Any RasterStack
filename	The output filename with a video extension, such as mp4, mkv, mov, or flv. For more information visit av::av_encode_video()
bbox	A vector with four values corresponding to xmin, ymin, xmax, ymax
outdir	Output directory for storing video frames (graphics). The default is a temporary folder
framerate	A number of frames per seconds. For more information visit av::av_encode_video()
width	The width the plot. The default is 7 (inches). For more information visit tmap::tmap_save()
height	The height of the plot. The default value is calculated automatically based on the RasterStack dimensions
dpi	The default is 100. For more information visit tmap::tmap_save()

Value

A video file
