A flat representation of the PDF graphics stream operators. Where the operator contains the asterisk character (not allowable in OCaml syntax), a prime is substituted.

val parse_single_stream : Pdf.t -> Pdf.pdfobject -> Pdfio.bytes -> t list

Parse a single byte streams to an operator list given a document and resource dictionary.

val parse_stream : Pdf.t -> Pdf.pdfobject -> Pdfio.bytes list -> t list

Parse a list of byte streams to an operator list given a document and resource dictionary.

val concat_bytess : Pdfio.bytes list -> Pdfio.bytes

Concatenate a list of bytes, padding with whitespace between.

val parse_operators : Pdf.t -> Pdf.pdfobject -> Pdf.pdfobject list -> t list

Given a pdf document, resource dictionary and list of streams representing the graphics content (PDF allows a single page's graphics content to be split over several streams), return a list of operators. Raises PDFError on bad content.

val stream_of_ops : t list -> Pdf.pdfobject

Flatten a list of operators to an uncompressed PDF stream.

val string_of_op : t -> string

Make a string of a single operator (for debug purposes).

val string_of_ops : t list -> string

Same as string_of_op, but of several operators (for debug purposes).

val components : Pdf.t -> Pdf.pdfobject -> Pdf.pdfobject -> int

Given a pdf, a resources dictionary and a colourspace dictionary, give the number of bytes per pixel in the stored image data.

val debug : bool ref

When this reference is set, some debug information is printed to Standard Output.
