brown.core.repeating_music_text_line

classes

A spanner of repeating music text over its length.

int: The number of text repetitions needed to cover the line.

This value rounds down, such that the real length of the drawn text will always be <= self.length.

__init__ (start, parent, end_x, text, end_parent=None, font=None, scale_factor=1) permalink view source

overriden from GraphicObject

arguments:

start (Point or init tuple): The starting point.

parent (GraphicObject): The parent of the starting point.

end_x (Unit): The end x position.

text (str, tuple, MusicChar, or list of these): The text to be repeated over the spanner, represented as a str (glyph name), tuple (glyph name, alternate number), MusicChar, or a list of them.

end_parent (GraphicObject): An optional parent of the end point. If omitted, the end position is relative to the main object.

font (MusicFont): The music font to be used. If not specified, the font is taken from the ancestor staff.

scale_factor (float): A hard scaling factor to be applied in addition to the size of the music font.

end_x: Unit The x position of the endpoint permalink view source

inherited from Spanner

end_y: Unit The y position of the endpoint permalink view source

inherited from Spanner

end_pos: Point The position of the endpoint permalink view source

inherited from Spanner

end_parent: GraphicObject The parent of the endpoint. permalink view source

self.end_pos is measured relative to this. To make self.end_pos relative to self.pos, simply set this to self.

inherited from Spanner

spanner_x_length: Unit The x-axis length of the spanner. permalink view source

Implementing subclasses will often want to override GraphicObject.length to return this.

inherited from Spanner

spanner_length: Unit The 2d length of the spanner. permalink view source

Note: This takes into account both the x and y axis. For only the horizontal length, use spanner_x_length.

staff: Staff The staff associated with this object permalink view source

inherited from StaffObject

pos_in_staff: Point The position of this object relative to the staff. permalink view source

This position is in non-flowed space.

inherited from StaffObject

length: Unit The breakable length of the object. permalink view source

This is used to determine how and where rendering cuts should be made.

bounding_rect: The bounding rect override for this text. permalink view source

inherited from Text

text: str The text to be drawn permalink view source

font: Font The text font permalink view source

inherited from Text

baseline_y: Unit The y coordinate of the first text line's baseline. permalink view source

scale_factor: float A hard scale factor to be applied to the rendered text permalink view source

inherited from Text

interfaces: set(GraphicObjectInterface) The interfaces for this object permalink view source

Interface objects are created upon calling GraphicObject.render()

Typically each GraphicObject will have one interface for each flowable line it appears in. Objects which fit completely in one visual line will typically have exactly one interface.

If this is an empty set, the object has not been rendered yet with the render() method.

pos: Point The position of the object relative to its parent. permalink view source

inherited from GraphicObject

x: Unit The x position of the object relative to its parent. permalink view source

inherited from GraphicObject

y: Unit The x position of the object relative to its parent. permalink view source

inherited from GraphicObject

pen: Pen The pen to draw outlines with permalink view source

inherited from GraphicObject

brush: Brush The brush to draw outlines with permalink view source

As a convenience, this may be set with a hex color string for a solid color brush of that color. For brushes using alpha channels and non-solid-color fill patterns, a fully initialized brush must be passed to this.

inherited from GraphicObject

parent: GraphicObject The parent object. permalink view source

If this is set to None, it defaults to the first page of the document.

inherited from GraphicObject

children: set(GraphicObject) All objects who have self as their parent. permalink view source

inherited from GraphicObject

descendants: iter[GraphicObject] All of the objects in the children subtree. permalink view source

This recursively searches all of the object's children (and their children, etc.) and provides an iterator over them.

The current implementation performs a simple recursive DFS over the tree, and has the potential to be rather slow.

read-only.

inherited from GraphicObject

ancestors: iter[GraphicObject] All ancestors of this object. permalink view source

Follows the chain of parents until a document page is reached. The iterable will not include the document Page.

The order begins with self.parent and traverses upward in the tree.

inherited from GraphicObject

flowable: Flowable or None The flowable this object belongs in. permalink view source

read-only.

inherited from GraphicObject

page_index: The index of the page this object appears on. permalink view source

>>> from brown.core import brown; brown.setup()
>>> some_object = GraphicObject((Mm(20), Mm(50)),
...                             parent=brown.document.pages[5])
>>> some_object.page_index
