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`, `SVGTRefElement`, and `SVGTextPathElement`.

| Constant | Value | Description |

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 constant values above.

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.

**Note:** In SVG 1.1 this method returned an `SVGPoint`.

`SVGTextContentElement.getEndPositionOfChar()`

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

**Note:** In SVG 1.1 this method returned an `SVGPoint`.

`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.
