Create base map. This is meant to be the deepest layer of contour plot map. Axes coordinates are supposed to be in meters.
Usage
createBaseMap(
imageFile,
domain = c(0, 0, 1000, 1000, 5, 5),
font_size = 10,
font_family = "sans"
)Arguments
- imageFile
(string) Path to the background 'png' file.
- domain
Six components vector with the domain SW corner coordinates, the X and Y extensions, and the number of breaks along the to axis (X, Y, DX, DY, NX, NY)
- font_size
This is the font size for axis labels
- font_family
This is the font family for labels
Examples
if (FALSE) {
# Import image 'img'. Divide the axis with 9 ticks.
v <- createBaseMap(img, c(minx, miny, extent, extent, 9, 9), font_size=10)
}
