R Documentation

Generates a legend bar (PNG file)

Description

Produces a PNG file that can be used as a screen overlay — legend bar for numeric and factor type variables.

Usage

kml_legend.bar(x, width, height, pointsize = 14, legend.file, legend.pal, 
     z.lim = range(x, na.rm=TRUE, finite=TRUE), factor.labels, png.type = "cairo-png")

Arguments

`x`	numeric or factor-type vector
`width`	numeric; (optional) width of image in pixels
`height`	numeric; (optional) height of image in pixels
`pointsize`	numeric; point size for the plot
`legend.file`	PNG file name
`legend.pal`	character; color palette
`z.lim`	numeric; lower and upper limits
`factor.labels`	character; class names if applicable
`png.type`	character; PNG type

Details

When exporting raster layers to KML the legend bar is generated by default. If the width and height are not provided, the function will try to estimate them automatically.
