x3p objects can be presented in different units. ISO standard 5436_2 asks for specification of values in meters.
For topographic surfaces collected by microscopes values in microns are
more readable. This functions allows to convert between different units.
Usage
x3p_scale_unit(x3p, scale_by)
Value
x3p with header information in microns
Arguments
x3p
object in x3p format, 3d topographic surface.
scale_by
numeric value. Value the surface to be scaled by. While not enforced, values of scale_by make most sense as multiples of 10 (for a metric system).
logo <- x3p_read(system.file("csafe-logo.x3p", package="x3ptools"))
