Print Basic Facts about a TransferFunction

Description

Each TransferFunction object is actually a list of so-called elementary transfer functions; for details on this see composition(). This print() calls an internal print() function for each elementary function individually. The internal print() also calls an internal validate() (with default arguments) which runs some basic tests and formats the results nicely for printing, see validate().

Usage

## S3 method for class 'TransferFunction'
print( x, ... )

Arguments

x	a TransferFunction object consisting of M elementary transfer functions
...	further arguments ignored, but required by the generic print()

Value

The function returns TRUE or FALSE.

Examples

tf = sRGB.EOTF^-1 * power.EOTF(2.5)
tf
##  #--------------------   [sRGB.EOTF]^-1    ---------------------#
##  [sRGB.EOTF]^-1 is a univariate TransferFunction.
##  domain:      [0,1]  (linear display)
##  range:       [0,1]  (non-linear signal)
##  invertible:  Yes
##  orientation: preserving
##  range-test points = 1300, max(distance)=0.
##  validation:  Passed
##  #--------------------   power.EOTF(2.5)    ---------------------#
##  power.EOTF(2.5) is a univariate TransferFunction.
##  domain:      [0,1]  (non-linear signal)
##  range:       [0,1]  (linear display)
##  invertible:  Yes
##  orientation: preserving
##  range-test points = 1300, max(distance)=0.
