entry in VexFlow.articulationCodes in tables.ts or Glyph code.
Notes default positions (see https://w3c.github.io/smufl/latest/tables/articulation.html):
Readonly typeArticulation code provided to the constructor.
Static DEBUGTo enable logging for this class. Set VexFlow.Articulation.DEBUG to true.
Returns the CSS compatible font string for the text font.
Provide a CSS compatible font string (e.g., 'bold 16px Arial') that will be applied to text (not glyphs).
a CSS font-size string (e.g., '18pt', '12px', '1em').
The size is 1) a string of the form '10pt' or '16px', compatible with the CSS font-size property. or 2) a number, which is interpreted as a point size (i.e. 12 == '12pt').
the font size in px.
the font size in pt.
a CSS font-style string (e.g., 'italic').
Set the font style.
a CSS font-weight string (e.g., 'bold'). As in CSS, font-weight is always returned as a string, even if it was set as a number.
Set the font weight.
Static CATEGORYArticulations category string.
Static PositionModifiers can be positioned almost anywhere, relative to a note.
Static PositionAdds a child Element to the Element, which lets it inherit the same style as the parent when setGroupStyle() is called.
Examples of children are noteheads and stems. Modifiers such as Accidentals are generally not set as children.
Note that StaveNote calls setGroupStyle() when setStyle() is called.
Add a class label (An element can have multiple class labels).
Apply the element style to context.
Validate and return the rendering context.
Check and get ModifierContext.
Return the element attributes.
Get the boundingBox.
Return the context, such as an SVGContext or CanvasContext object.
Get ModifierContext.
Get the element style used for rendering.
Call back from registry after the element is registered.
Remove a class label (An element can have multiple class labels).
Render the element text.
Restore the style of context.
Set an attribute such as 'id', 'class', or 'type'.
Set if articulation should be rendered between lines.
Set the context to an SVGContext or CanvasContext object
Optional context: RenderContextSet the element's text font family, size, weight, style
(e.g., Arial, 10pt, bold, italic).
This attribute does not determine the font used for musical Glyphs like treble clefs.
Optional font: string | FontInfois 1) a FontInfo object or
2) a string formatted as CSS font shorthand (e.g., 'bold 10pt Arial') or
3) a string representing the font family (at least one of size, weight, or style must also be provided).
Optional size: string | numbera string specifying the font size and unit (e.g., '16pt'), or a number (the unit is assumed to be 'pt').
Optional weight: string | numberis a string (e.g., 'bold', 'normal') or a number (100, 200, ... 900).
Optional style: stringis a string (e.g., 'italic', 'normal').
If no arguments are provided, then the font is set to the default font.
Each Element subclass may specify its own default by overriding the static TEXT_FONT property.
Change the font size, while keeping everything else the same.
Optional size: string | numberSet the element & associated children style used for rendering.
Set note index, which is a specific note in a chord.
Every modifier must be part of a ModifierContext.
Set attached note.
(StaveNote, TabNote, etc.)
Set position.
CENTER | LEFT | RIGHT | ABOVE | BELOW
Set the rendered status.
Set the element style used to render.
Example:
element.setStyle({ fillStyle: 'red', strokeStyle: 'red' });
element.draw();
Note: If the element draws additional sub-elements (ie.: Modifiers in a Stave), the style can be applied to all of them by means of the context:
element.setStyle({ fillStyle: 'red', strokeStyle: 'red' });
element.getContext().setFillStyle('red');
element.getContext().setStrokeStyle('red');
element.draw();
or using drawWithStyle:
element.setStyle({ fillStyle: 'red', strokeStyle: 'red' });
element.drawWithStyle();
Set element text.
Set the textLine for the modifier.
Set element width.
Set the X coordinate.
Shift modifier x pixels in the direction of the modifier. Negative values
shift reverse.
Set the Y coordinate.
Shift modifier down y pixels. Negative values shift up.
Static easyStatic formatFIXME: Most of the complex formatting logic (ie: snapping to space) is actually done in .render(). But that logic belongs in this method.
Unfortunately, this isn't possible because, by this point, stem lengths have not yet been finalized. Finalized stem lengths are required to determine the initial position of any stem-side articulation.
This indicates that all objects should have their stave set before being formatted. It can't be an optional if you want accurate vertical positioning. Consistently positioned articulations that play nice with other modifiers won't be possible until we stop relying on render-time formatting.
Ideally, when this function has completed, the vertical articulation positions should be ready to render without further adjustment. But the current state is far from this ideal.
