SVGTextContentElement

The SVGTextContentElement interface is implemented by elements that support rendering child text content. It is inherited by various text-related interfaces, such as SVGTextElement, SVGTSpanElement, and SVGTextPathElement.

Instance properties

This interface also inherits properties from its parent, SVGGraphicsElement.

SVGTextContentElement.textLength Read only

An SVGAnimatedLength reflecting the textLength attribute of the given element.

SVGTextContentElement.lengthAdjust Read only

An SVGAnimatedEnumeration reflecting the lengthAdjust attribute of the given element. The numeric type values represent one of the LENGTHADJUST_* constant values.

Instance methods

This interface also inherits methods from its parent, SVGGraphicsElement.

SVGTextContentElement.getNumberOfChars()

Returns a long representing the total number of addressable characters available for rendering within the current element, regardless of whether they will be rendered.

SVGTextContentElement.getComputedTextLength()

Returns a float representing the computed length for the text within the element.

SVGTextContentElement.getSubStringLength()

Returns a float representing the computed length of the formatted text advance distance for a substring of text within the element. Note that this method only accounts for the widths of the glyphs in the substring and any extra spacing inserted by the CSS 'letter-spacing' and 'word-spacing' properties. Visual spacing adjustments made by the 'x' attribute is ignored.

SVGTextContentElement.getStartPositionOfChar()

Returns a DOMPoint representing the position of a typographic character after text layout has been performed.

SVGTextContentElement.getEndPositionOfChar()

Returns a DOMPoint representing the trailing position of a typographic character after text layout has been performed.

SVGTextContentElement.getExtentOfChar()

Returns a DOMRect representing the computed tight bounding box of the glyph cell that corresponds to a given typographic character.

SVGTextContentElement.getRotationOfChar()

Returns a float representing the rotation of typographic character.

SVGTextContentElement.getCharNumAtPosition()

Returns a long representing the character which caused a text glyph to be rendered at a given position in the coordinate system. Because the relationship between characters and glyphs is not one-to-one, only the first character of the relevant typographic character is returned.

SVGTextContentElement.selectSubString() Deprecated

Selects text within the element.

Static properties
