Style:: (61 methods):

Class: Style  - X-Ref

Represents CSS properties.

The Style class is responsible for handling and storing CSS properties.
It includes methods to resolve colours and lengths, as well as getters &
setters for many CSS properites.

Actual CSS parsing is performed in the {@link Stylesheet} class.

param: Stylesheet $stylesheet the stylesheet this Style is associated with.

dispose()   X-Ref

returns the {@link Stylesheet} this Style is associated with.

return: Stylesheet

length_in_pt($length, $ref_size = null)   X-Ref
Converts any CSS length value into an absolute length in points.

length_in_pt() takes a single length (e.g. '1em') or an array of
lengths and returns an absolute length.  If an array is passed, then
the return value is the sum of all elements.

If a reference size is not provided, the default font size is used
({@link Style::$default_font_size}).
