Attributes

clazz	CSS class string.
default_sheet
id
parent_fml
propagators
vertices
legs
sheet
style	CSS style string.

add_rule(rule: str)

Add a rule to the style.

add_rules(rules: str)

Add rules to the style.

clazz: str | None = None

CSS class string.

classmethod from_xml(xml: str)

Load self from XML.

classmethod from_xml_file(file: str)

Load self from XML file.

get_bounding_box()

Get the bounding box of the diagram, i.e. the smallest rectangle that contains all vertices and legs.

Returns:

The bounding box

Return type:

(min_x, min_y, max_x, max_y)

get_sheet()

Return the sheet.

get_sheets()

Return the sheet.

get_style(obj, xml: XML | None = None) → CSSStyleDeclaration

Get the style of an object.

This is prefered over accessing the style attribute directly, since it includes class and pdgid definitions.

get_style_property(obj, property_name, xml: XML | None = None) → str

Get a style property of an object.

put_style(key, value)

Deprecated since version 0.0.0.

put_styles(**kwargs)

Deprecated since version 0.0.0.

scale_positions(scale)

Scale the positions of the vertices and legs.

style: CSSString

CSS style string.

to_xml() → str

Return self as XML.

with_id(id: str)

set id

with_legs(value, k='legs')

Set legs to value and return self.

with_new_id()

generate new id

with_propagators(value, k='propagators')

Set propagators to value and return self.

with_rule(rule: str)

Replace rules of the style.

with_rules(rules: str)

Replace rules of the style.

with_sheet(sheet)

Return the object with the sheet.

with_vertices(value, k='vertices')

Set vertices to value and return self.
