val parse_function : Pdf.t -> Pdf.pdfobject -> t

Parse a function given a document and function object.

exception BadFunctionEvaluation of string

Raised from eval_function (see below) in the case of inputs which don't match the evaluation

val eval_function : t -> float list -> float list

Evaluate a function given a list of inputs.

val pdfobject_of_function : Pdf.t -> t -> Pdf.pdfobject

Flatten a function to its PDF representation

val print_function : t -> unit

Print a function to Standard Output. For debug only.
