hc_png-HilbertCurve-method {HilbertCurve} | R Documentation |
Save Hilbert curve as a PNG figure
## S4 method for signature 'HilbertCurve' hc_png(object, file = "HilbertCurve.png")
object |
A |
file |
file name. If the suffix of the file name is not |
A PNG figure with resolution of 2^level x 2^level
is generated.
Only the body of the Hilbert curve will be written to PNG file.
This function only works under 'pixel' mode.
No value is returned.
