Module Svg_types 

module Svg_types : sig..end

SVG types with variants. (See also Svg.M)

This module defines basic data types for data, attributes and element occuring in SVG documents. It is based on the specification available at http://www.w3.org/TR/SVG/.

This module is experimental, it may lack of some attributes, and the interface is very low level and do not take deeply into account the needs of SVG elements.

Categories of elements and attributes

This part defines the categories of elements and attributes

Generic data types 

type iri = string

An IRI reference is an Internationalized Resource Identifier with an optional fragment identifier, as defined in Internationalized Resource Identifiers RFC3987. An IRI reference serves as a reference to a resource or (with a fragment identifier) to a secondary resource. See References and the ‘defs’ element..

Units 

module Unit : sig..end

SVG defines several units to measure time, length, angles.

type transform =  | Matrix of (float * float * float * float * float * float) | Translate of (float * float option) | Scale of (float * float option) | Rotate of (Unit.angle * (float * float) option) | SkewX of Unit.angle | SkewY of Unit.angle
