Class Detail
PDFNet.Function(id)
Although PDF is not a programming language it provides several types of function
object that represent parameterized classes of functions, including mathematical
formulas and sampled representations with arbitrary resolution. Functions are used
in various ways in PDF, including device-dependent rasterization information for
high-quality printing (halftone spot functions and transfer functions), color
transform functions for certain color spaces, and specification of colors as a
function of position for smooth shadings. Functions in PDF represent static,
self-contained numerical transformations.
PDF::Function represents a single, flat interface around all PDF function types.
PDF::Function represents a single, flat interface around all PDF function types.
- Parameters:
- id
Method Detail
assign(right)
Copy Constructor
- Parameters:
- {Function} right
- (generated documentation)
<static>
{Function}
PDFNet.Function.create(funct_dict)
create a PDF::Function object from an existing SDF function dictionary. If funct_dict
is null, a non valid Function object is created.
- Parameters:
- {Obj} funct_dict
- (generated documentation)
- Returns:
- {Function} A promise that resolves to an object of type: "Function" (generated documentation)
destroy()
Frees the native memory of the object.
eval(inval, outval)
[Documentation Not Yet Added]
- Parameters:
- {number} inval
- (generated documentation)
- {number} outval
- (generated documentation)
{number}
getInputCardinality()
- Returns:
- {number} A promise that resolves to the number of input components required by the function
{number}
getOutputCardinality()
- Returns:
- {number} A promise that resolves to the number of output components returned by the function
{Obj}
getSDFObj()
- Returns:
- {Obj} A promise that resolves to the underlying SDF/Cos object
{number}
getType()
Return value enum:
PDFNet.Function.Type = {
e_sampled : 0
e_exponential : 2
e_stitching : 3
e_postscript : 4
}
- Returns:
- {number} A promise that resolves to the function type
