The SVGTextContentElement is inherited by various text-related
interfaces, such as SVGTextElement, SVGTSpanElement,
SVGTRefElement, SVGAltGlyphElement and
SVGTextPathElement.
| Properties |
|---|
| const unsigned short | - LENGTHADJUST_SPACING = 1
- Corresponds to value 'spacing'.
|
| const unsigned short | - LENGTHADJUST_SPACINGANDGLYPHS = 2
- Corresponds to value 'spacingAndGlyphs'.
|
| const unsigned short | - LENGTHADJUST_UNKNOWN = 0
- The enumeration was set to a value that 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.
|
| SVGAnimatedString | - className
- Corresponds to attribute ‘class’ on the given element.
|
| SVGAnimatedBoolean | - externalResourcesRequired
- Corresponds to attribute ‘externalResourcesRequired’ on the given
element. Note that the SVG DOM defines the attribute
‘externalResourcesRequired’ as being of type
SVGAnimatedBoolean, whereas the SVG language definition says that
‘externalResourcesRequired’ is not animated.
|
| SVGAnimatedEnumeration | - lengthAdjust
- Corresponds to attribute ‘lengthAdjust’ on
the given element. The value must be one of the length adjust constants
defined on this interface.
|
| SVGStringList | - requiredExtensions
- Corresponds to attribute ‘requiredExtensions’ on the given element.
|
| SVGStringList | - requiredFeatures
- Corresponds to attribute ‘requiredFeatures’ on the given element.
|
| CSSStyleDeclaration | - style
- Corresponds to attribute ‘style’ on the given element. If the
user agent does not support styling
with CSS, then this attribute must always have the value of null.
|
| SVGStringList | - systemLanguage
- Corresponds to attribute ‘systemLanguage’ on the given element.
|
| SVGAnimatedLength | - textLength
- Corresponds to attribute ‘textLength’ on
the given element.
|
| DOMString | - xmllang
- Corresponds to attribute ‘xml:lang’ on the given element. Exceptions on settingDOMException, code NO_MODIFICATION_ALLOWED_ERR Raised on an
attempt to change the value of a read only attribute.
|
| DOMString | - xmlspace
- Corresponds to attribute ‘xml:space’ on the given element. Exceptions on settingDOMException, code NO_MODIFICATION_ALLOWED_ERR Raised on an
attempt to change the value of a read only attribute.
|
| Operations |
|---|
| long | - getCharNumAtPosition(SVGPoint point)
- Returns the index of the character whose corresponding glyph cell
bounding box contains the specified point. The calculations assume that
all glyphs occupy the full standard glyph cell for the font. If no such
character exists, a value of -1 is returned.
|
| float | - getComputedTextLength()
- The total sum of all of the advance values from rendering all of the
characters within this element, including the advance value on the
glyphs (horizontal or vertical), the effect of properties
‘kerning’, ‘letter-spacing’ and ‘word-spacing’ and
adjustments due to attributes ‘dx’ and ‘dy’ on
‘tspan’ elements.
|
| SVGPoint | - getEndPositionOfChar(unsigned long charnum)
- Returns the current text position after rendering the character in the
user coordinate system for rendering the glyph(s) that correspond to
the specified character. This current text position does not take into
account the effects of any inter-character adjustments to prepare for
the next character, such as properties ‘kerning’,
‘letter-spacing’ and ‘word-spacing’ and adjustments due to
attributes ‘x’,
‘y’, ‘dx’
and ‘dy’.
|
| SVGRect | - getExtentOfChar(unsigned long charnum)
- Returns a tightest rectangle which defines the minimum and maximum X and
Y values in the user coordinate system for rendering the glyph(s) that
correspond to the specified character. The calculations assume that all
glyphs occupy the full standard glyph cell for the font.
|
| long | - getNumberOfChars()
- Returns the total number of characters available for rendering within
the current element, which includes referenced characters from
‘tref’ reference, regardless of whether they will be rendered. Effectively, this is equivalent to the length of the
Node::textContent
attribute from DOM Level 3 Core ([DOM3],
section 1.4), if that attribute also expanded ‘tref’
elements.
|
| CSSValue | - getPresentationAttribute(DOMString name)
- Returns the base (i.e., static) value of a given presentation attribute as an object of type CSSValue. The returned object
is live; changes to the objects represent immediate changes to the
objects to which the CSSValue is attached. Note: The getPresentationAttribute method is deprecated,
and may be dropped from future versions of the SVG specification.
|
| float | - getRotationOfChar(unsigned long charnum)
- Returns the rotation value relative to the current user coordinate
system used to render the glyph(s) corresponding to the specified
character. If multiple glyph(s) are used to render the given character
and the glyphs each have different rotations (e.g., due to
text-on-a-path), the user agent shall return an average value (e.g., the
rotation angle at the midpoint along the path for all glyphs used to
render this character).
|
| SVGPoint | - getStartPositionOfChar(unsigned long charnum)
- Returns the current text position before rendering the character in the
user coordinate system for rendering the glyph(s) that correspond to
the specified character. The current text position has already taken
into account the effects of any inter-character adjustments due to
properties ‘kerning’, ‘letter-spacing’ and
‘word-spacing’ and adjustments due to attributes
‘x’, ‘y’,
‘dx’ and
‘dy’.
|
| float | - getSubStringLength(unsigned long charnum, unsigned long nchars)
- The total sum of all of the advance values from rendering the specified
substring of the characters, including the advance value on the glyphs
(horizontal or vertical), the effect of properties ‘kerning’,
‘letter-spacing’ and ‘word-spacing’ and adjustments due to
attributes ‘dx’ and ‘dy’ on ‘tspan’ elements.
|
| boolean | - hasExtension(DOMString extension)
- Returns true if the user agent supports the given extension, specified
by a URI. ParametersDOMString extension The name of the extension, expressed as a URI. Returns True or false, depending on whether the given extension is
supported.
|
| void | - selectSubString(unsigned long charnum, unsigned long nchars)
- Causes the specified substring to be selected just as if the user
selected the substring interactively. Parametersunsigned long charnum The index of the start character which is at the given
point, where the first character has an index of 0. unsigned long nchars The number of characters in the substring.
