PathSegment-class

applyTransform,PathSegment,matrix-method

A segment of a path that is not intended to be used directly, merely
 as a convenience base class for path segment operators.

Functions for importing external vector images and
drawing them as part of 'R' plots.  This package is different from the
'grImport' package because, where that package imports 'PostScript'
format images, this package imports 'SVG' format images.  Furthermore,
this package imports a specific subset of 'SVG', so external images
must be preprocessed using a package like 'rsvg' to produce 'SVG'
that this package can import.  'SVG' features that are not supported
by 'R' graphics, e.g., gradient fills, can be imported and then
exported via the 'gridSVG' package.

<dl>
 <dt>applyTransform</dt>
<dd><code>signature(object = "PathSegment", tm =
 "matrix")</code>: When given a 3x3 numeric transformation matrix, the
 points in the segment are transformed, and produce a new object
 representing a path segment. Not intended to be used directly on
 path segments, but objects that inherit from path segments
 (e.g. the <code>"M"</code>, <code>"L"</code>, <code>"C"</code>, and <code>"Z"</code>
 operators.</dd>
