Attributes

x

This attribute defines the corresponding absolute x-coordinates for rendering the element. Value type: <list-of-coordinates> ; Default value: Absolute x-coordinate of ancestor <text> or <tspan>; Animatable: yes

y

This attribute defines the corresponding absolute y-coordinates for rendering the element. Value type: <list-of-coordinates> ; Default value: Absolute y-coordinate of ancestor <text> or <tspan>; Animatable: yes

dx

This attribute indicates a shift along the x-axis on the position of the element. Value type: <list-of-coordinates> ; Default value: Relative x-coordinate of ancestor <text> or <tspan>; Animatable: yes

dy

This attribute indicates a shift along the x-axis on the position of the element. Value type: <list-of-coordinates> ; Default value: Relative y-coordinate of ancestor <text> or <tspan>; Animatable: yes

rotate

This attribute defines the supplemental rotation that will be applied to the element. Value type: <list-of-numbers> ; Default value: none; Animatable: yes (non-additive)

glyphRef

format

The format of the given font. Value type: <string> ; Default value: none; Animatable: no

xlink:href

An <iri> reference either to a <glyph> element in an SVG document or to an <altGlyphDef> element.

If the reference is to a <glyph> element and that glyph is available, then that glyph is rendered instead of the character(s) that are inside of the <altGlyph> element.

If the reference is to an <altGlyphDef> element, then if an appropriate set of alternate glyphs is located from processing the <altGlyphDef> element, then those alternate glyphs are rendered instead of the character(s) that are inside of the <altGlyph> element. Value type: <iri> ; Default value: none; Animatable: no
