utils.dom.getFastTextWidth() function

Gets the width of a text element using a faster method than getTextWidth. This method requires that we know the text element's font family and size in advance. Similar to getTextWidth, we cache the width we compute.

Signature:

export declare function getFastTextWidth(textElement: SVGTextElement, fontSize: number, fontWeight: string, fontFamily: string): number;

Parameters

Parameter	Type	Description
textElement	SVGTextElement	An SVG 'text' element.
fontSize	number	The font size to use.
fontWeight	string	The font weight to use.
fontFamily	string	The font family to use.

Returns:

number

Width of element.
