In addition to the methods listed above, class
RVG::ClipPath also implements the styles method and the shape methods.
class methods
new
RVG::ClipPath.new(clip_path_units)
[ { |clippath| drawing method calls }
] -> aClipPath
Description
Creates a clipping path. A clipping path is a
combination of path, text, and basic shape objects that define
an outline. Attach the clipping path to an object such as a
raster image or RVG object with the :clip_path style. When RVG
draws the object, things "outside" the path are not drawn.
The ClipPath.new method yields to a block. Within the block
define the clipping path with a combination of path, basic
shape, and text objects. You can also use
the use method to refer to a
previously-defined object or group of objects.
Arguments
- clip_path_units
- Defines the coordinate system for the contents of the
clipping path. This argument can take either of two values,
userSpaceOnUse, or
objectBoundingBox. If
userSpaceOnUse, the contents of the clipping
path represent values in the current user coordinate system
in place at the time when the clipping path is referenced. if
objectBoundingBox, then the user coordinate system for the
contents of the clipping path is established using the
bounding box of the object to which the clipping path is
applied. The default is userSpaceOnUse.
Example
See Also
The :clip_rule style.
attributes
desc, desc=
clippath.desc -> aString
clippath.desc = aString
Description
Use the desc attribute to
assign a text description to the clipping path.
clippath.metadata ->
aString
clippath.metadata = aString
Description
Use the metadata attribute to
assign additional metadata to the clipping path.
title, title=
clippath.title -> aString
clippath.title = aString
Description
Use the title attribute to
assign a title to the clipping path.
instance methods
text
clippath.text(x=0, y=0, text=nil) [{|aText| ...}]
-> aText
Description
Calls RVG::Text.new to
construct a text object and adds it to the clipping path.
Yields to a block if one is present, passing the new text
object as an argument.
Returns
The RVG::Text object, so other
RVG::Text methods can be chained to this
method.
use
clippath.use(obj, x=0, y=0, width=nil,
height=nil) -> aUse
Description
Calls RVG::Use.new to
constructs a use object and adds it to the
clipping path.
When the referenced argument is another RVG object,
width and height can be used to specify the width and height
of the viewport. If present and non-nil, these arguments
override any width and height specified when the RVG object was
created. You must specify the viewport size either when
creating the RVG object or when referencing it with
use.
Examples
See RVG::Use.new
Returns
The RVG::Use object, so other
RVG::Use methods can be chained to this
method.
