dee 0.1.1

Initial features

• dee() creates “dee” class objects.

  • Can be plotted with plot.dee() if suggested packages omsvg and nanosvgr are installed.
  • Can be converted to an omsvg “svg” class object with as_omsvg() if suggested package omsvg is installed.

• dee_options() returns a list of (current or default) dee package option values.

• Absolute coordinate svg d path command helpers:

  • A(), AZ() are the elliptical arc curve commands.
  • C(), CZ(), S(), SZ() are the cubic Bézier curve commands.
  • L(), LZ(), H(), HZ(), V(), VZ() are the “lineto” commands.
  • M(), MZ() are the “moveto” commands.
  • Q(), QZ(), T(), TZ() are the quadratic Bézier curve commands.
  • Z() is the “closepath” command.

• Relative coordinate svg d path command helpers:

  • aa(), az() are the elliptical arc curve commands.
  • cc(), cz(), ss(), sz() are the cubic Bézier curve commands.
  • ll(), lz(), hh(), hz(), vv(), vz() are the “lineto” commands.
  • mm(), mz() are the “moveto” commands.
  • qq(), qz(), tt(), tz() are the quadratic Bézier curve commands.
  • zz() is the “closepath” command.

• svg d path convenience wrappers:

  • d_aabb() is a wrapper around d_rect() to create an axis-aligned bounding box.

  • d_arc1() d_arc2(), d_arc3(), d_arc4(), d_arc12(), d_arc23(), d_arc34(), d_arc41(), d_arc123(), d_arc234(), d_arc341(), and d_arc412() are wrappers to create elliptical arc paths.

  • d_fslash() and d_bslash() are wrappers around MZ() to build forward/backward slash paths.

  • d_ellipse() is a wrapper around M() and AZ() to build ellipse paths.

    • d_circle() is a wrapper around d_ellipse() to build circle paths.

  • d_polygon() is a wrapper around MZ() to build polygon paths. If its argument offset is nonzero will compute an offset region.

    • d_isotoxal_2ngon() is a wrapper around d_polygon() to create isotoxal 2n-gon polygons. d_star() is an alias.
    • d_regular_ngon() is a wrapper around d_polygon() to create regular polygons.

  • d_rect() is a wrapper around d_polygon() to build rectangle paths.

• Miscellaneous helper functions:

  • height_slash_left(), height_slash_right(), width_slash_left(), and width_slash_right() return the height or width of the left or right end of a d_fslash() or d_bslash() shape.
  • x_ellipse_left(), x_ellipse_right(), y_ellipse_top(), and y_ellipse_bottom() return the leftmost/rightmost x-coordinate or topmost/bottommost y-coordinate on a (possibly rotated) ellipse at a given y or x value.
