class PostScriptCalculatorFunction : Function

Namespace:Datalogics::PDFL

Inherits from:: Function

Detailed Description

A function represented as a stream containing code written in a small subset of the PostScript language.

Uses types

Constructor & Destructor Documentation

PostScriptCalculatorFunction(System.Collections.Generic.IList< System.Double > domain, System.Collections.Generic.IList< System.Double > range, string code)

Parameters

domain: System.Collections.Generic.IList< System.Double >: an array of 2 * m numbers, where m is the number of input values
range: System.Collections.Generic.IList< System.Double >: an array of 2 * n numbers, where n is the number of output values
code: string: the code of the function, written in a subset of the PostScript language

Create PostScript calculator function, represented as a stream containing code written in a small subset of the PostScript language.

Property Documentation

string Code[get]

The code of the function, written in a subset of the PostScript language.

The code defines how input values are transformed into output values.

static Function Default[get]

Gets the Default named function.

A Function representing the Default named function.

System.Collections.Generic.IList< System.Double > Domain[get, set]

The domain of the function.

Contains 2 * m elements, where m is the number of inputs to the function. Each successive pair of elements gives the minimum and maximum values for one of the inputs. Input values to the function are clamped to these minimum and maximum values.

static Function Identity[get]

Gets the Identity named function.

A Function representing the Identity named function, which returns its input values unchanged.

int NInputs[get]

The number of inputs to the function.

int NOutputs[get]

The number of outputs from the function.

System.Collections.Generic.IList< System.Double > Range[get, set]

The range of the function.

Contains 2 * n elements, where n is the number of outputs from the function. Each successive pair of elements gives the minimum and maximum values for one of the outputs. Output values from the function are clamped to these minimum and maximum values.

PDFStream Stream[get]

The underlying PDF stream for this PostScriptCalculatorFunction.

The stream contains the PostScript code that defines the function.

Member Function Documentation

System.Collections.Generic.IList< System.Double > Apply(System.Collections.Generic.IList< System.Double > args)

Parameters

args: System.Collections.Generic.IList< System.Double >: input values for the function. The number of input values must agree with the number of inputs the function takes.

Returns:

System.Collections.Generic.IList< System.Double >

a list of the result values from the function

Apply the function to supplied input values

void Dispose()

Returns:

void

override string ToString()

Returns:

override string

A string representation of the PostScriptCalculatorFunction, including the number of inputs and outputs, domain, range, and the PostScript code.

A string value describing the function.

static bool operator!=(Function a, Function b)

Parameters

a: Function: The first Function to compare.
b: Function: The second Function to compare.

Returns:

bool

true if the two Functions are not equal; otherwise, false.

Tests two Function objects for inequality.

static bool operator==(Function a, Function b)

Parameters

a: Function: The first Function to compare.
b: Function: The second Function to compare.

Returns:

bool

true if the two Functions are equal; otherwise, false.

Tests two Function objects for equality.
