Module: Postsvg::Visitors::PsVisitor::Path

Included in:
Postsvg::Visitors::PsVisitor
Defined in:
lib/postsvg/visitors/ps_visitor/path.rb

Overview

Path construction operator handlers. Each appends a command to @path (PathState). CTM-aware: when the current CTM is not identity, the renderer will wrap emitted paths in a <g transform=>. Points are stored in user-space coordinates; the visitor delegates to the SvgBuilder for transform emission.
