prepareRaster: Prepare raster for plotting

In quickPlot: A System of Plotting Optimized for Speed and Modularity

Prepare raster for plotting

Description

Internal function. Takes a raster .quickPlotGrob, and converts zoomExtent into a zoom, and legendRange into a legend. Then calculates the maxpixels to plot for speed.

Usage

.prepareRaster(
  grobToPlot,
  zoomExtent,
  legendRange,
  takeFromPlotObj,
  arr,
  speedup,
  newArr
)

Arguments

grobToPlot	A .quickPlotGrob object.
zoomExtent	an extent object
legendRange	a numeric vector of length >=2 indicating the desired legend range.
takeFromPlotObj	logical. Should the object be found in the Plot call or .GlobalEnv
arr	an .arrangement object
speedup	numeric, greater than 1 will usually speed up plotting at the expense of resolution
newArr	logical, whether this is a new arrangement or just adding to a previous one
