In addition to the methods listed above,
class RVG::Tspan also implements the styles method.
class methods
new
RVG::Tspan.new(text=nil, x=0, y=0) [
{ |tspan| ...} ] -> tspan
Description
This method may be invoked indirectly via the
tspan method in RVG::Text.
Tspan objects are containers, so this method yields to a block if one is present. The only objects that a tspan can contain are other tspans. Styles
defined on a tspan propagate to any tspans contained within it.
Arguments
All arguments are optional.
- text
-
A string. If present, this string is drawn at the current text position. By default the string is positioned with the lower-left corner of the first
glyph at the current text position. Use the
:text_anchor style to override this behavior. After the string is rendered, the current text position is moved
to the end of the string.
- x, y
- Specify a new current text position within the current user coordinate system.
Examples
instance methods
d
tspan.d(dx[, dy=0]) [ { |self| ...} ] ->
self
Description
The dx and dy arguments are added to the the current text position to form a new current text
position. Yields to a block if one is present.
Arguments
- dx, dy
- The distance, in the user coordinate system, to be added to the current text position.
Example
Returns
self
rotate
tspan.rotate(degrees) [ { |self| ...} ] -> self
Description
Rotates the text about the current text position by the specified number of degrees. Yields to a block if one is present.
Arguments
- degrees
- The amount of rotation
Example
Returns
self
tspan
tspan.tspan(string=0, x=nil, y=0) [
{ |tspan| ...} ] -> tspan
Description
Calls RVG::Tspan.new to construct a tspan and adds it to the tspan. Yields to a block if one is present, passing the new tspan as an
argument. Styles defined on the container tspan propagate to the contained tspan.
Arguments
- string
- A text string.
- x, y
- A new initial text position
Returns
The new tspan, so other RVG::Tspan methods can be chained to it.
