Module dict

Parsing for PostScript DICTs.

Structs

BcdComponents

Components for computing a fixed point value for a binary coded decimal number.

Blues

Operand for the BlueValues, OtherBlues, FamilyBlues and FamilyOtherBlues operators.

StemSnaps

Operand for the StemSnapH and StemSnapV operators.

Enums

Entry

PostScript DICT Operator with its associated operands.

Operator

PostScript DICT operator.

Token

Either a PostScript DICT operator or a (numeric) operand.

MAX_STEM_SNAPS 🔒

Summary: older PostScript interpreters accept two values, but newer ones accept 12. We’ll assume that as maximum. https://adobe-type-tools.github.io/font-tech-notes/pdfs/5049.StemSnap.pdf
