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 listParse 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 listParse a list of byte streams to an operator list given a document and resource dictionary.
val concat_bytess : Pdfio.bytes list -> Pdfio.bytesConcatenate a list of bytes, padding with whitespace between.
val parse_operators : Pdf.t -> Pdf.pdfobject -> Pdf.pdfobject list -> t listGiven 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.pdfobjectFlatten a list of operators to an uncompressed PDF stream.
val string_of_op : t -> stringMake a string of a single operator (for debug purposes).
val string_of_ops : t list -> stringSame as string_of_op, but of several operators (for debug purposes).
val components : Pdf.t -> Pdf.pdfobject -> Pdf.pdfobject -> intGiven a pdf, a resources dictionary and a colourspace dictionary, give the number of bytes per pixel in the stored image data.
