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.

• textLength Read only
  • : An SVGAnimatedLength reflecting the textLength attribute of the given element.
• 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.

• 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.
• getComputedTextLength()
  • : Returns a float representing the computed length for the text within the element.
• 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.
• getStartPositionOfChar()
  • : Returns a DOMPoint representing the position of a typographic character after text layout has been performed.
• getEndPositionOfChar()
  • : Returns a DOMPoint representing the trailing position of a typographic character after text layout has been performed.
• getExtentOfChar()
  • : Returns a DOMRect representing the computed tight bounding box of the glyph cell that corresponds to a given typographic character.
• getRotationOfChar()
  • : Returns a float representing the rotation of typographic character.
• 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.
• selectSubString() Deprecated
  • : Selects text within the element.

Static properties

• LENGTHADJUST_UNKNOWN (0)
  • : The type is not one of predefined types. It is invalid to attempt to define a new value of this type or to attempt to switch an existing value to this type.
• LENGTHADJUST_SPACING (1)
  • : Corresponds to the value spacing.
• LENGTHADJUST_SPACINGANDGLYPHS (2)
  • : Corresponds to the value spacingAndGlyphs.
