Description Slots Extends Methods Author(s) See Also

A description of a clipping path that is meant to be used as part of a larger picture (as it does not directly draw anything itself). This is primarily used for determining the bounding box of the clipping region (because R graphics only supports rectangular clipping regions). This object will have a greater effect with it is used in conjunction with the gridSVG package as it can apply non-rectangular clipping regions.

content:: Object of class "list". A list of "PictureContent" objects that describe the outline(s) of the clipping region(s).
label:: Object of class "character". A label to identify the clipping path by so that it may be referred to by content within the image.

Class PictureContent, directly.

grobify

signature(object = "PictureClipPath"): convert the clipping path into a grid grob. Useful only in conjunction with the gridSVG package for non-rectangular paths.

This grobify method takes three arguments:

defs: Required. This argument expects a "PictureDefinitions" object that contains referenced content.
gpFUN: A function that takes a gpar object and returns a modified gpar object. The default value for this arugment is the identity function.
ext: A character vector. See grid.picture for more information on what this extension selection parameter means, in addition to the valid values this argument takes.
