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, SVGAltGlyphElement and SVGTextPathElement.

Constants
| Constant | Value | Description |
| LENGTHADJUST_UNKNOWN | 0 | Some other value. |
| LENGTHADJUST_SPACING | 1 | The spacing keyword. |
| LENGTHADJUST_SPACINGANDGLYPHS | 2 | The spacingAndGlyphs keyword. |
Properties
This interface also inherits properties from its parent, SVGGraphicsElement.
SVGTextContentElement.textLengthRead only- An
SVGAnimatedLengthreflecting thetextLengthattribute of the given element. SVGTextContentElement.lengthAdjustRead only- An
SVGAnimatedEnumerationreflecting thelengthAdjustattribute of the given element. The numeric type values represent one of the constant values above.
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
DOMPointrepresenting 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
DOMPointrepresenting 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
DOMRectrepresenting 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()- Selects text within the element.
Specifications
| Specification | Status | Comment |
|---|---|---|
| Scalable Vector Graphics (SVG) 2 The definition of 'SVGTextContentElement' in that specification. |
Candidate Recommendation | Changed inheritance from SVGElement to SVGGraphicsElement and getStartPositionOfChar() and removed implementations of SVGTests, SVGLangSpace, SVGExternalResourcesRequired, SVGStylable interfaces and getEndPositionOfChar() to return a DOMPoint instead of an SVGPoint. |
| Scalable Vector Graphics (SVG) 1.1 (Second Edition) The definition of 'SVGTextContentElement' in that specification. |
