|phoenix_title|  **wx.svg._nanosvg.SVGimageBase**
==========================================================================================================================================

A SVGimageBase can be created either from an SVG file or from an in-memory
buffer containing the SVG XML code. The result is a collection of cubic
bezier shapes, with fill, stroke, gradients, paths and other information.

This class is a Cython-based wrapper around the nanosvg ``NSVGimage`` structure,
providing just the basic wrapped functionality from nanosvg. Please see the
:class:`wx.svg.SVGimage` class for a derived implementation that adds
functionality for integrating with wxPython.

.. class:: SVGimageBase(object)

   A SVGimageBase can be created either from an SVG file or from an in-memory
   buffer containing the SVG XML code. The result is a collection of cubic
   bezier shapes, with fill, stroke, gradients, paths and other information.
   
   This class is a Cython-based wrapper around the nanosvg ``NSVGimage`` structure,
   providing just the basic wrapped functionality from nanosvg. Please see the
   :class:`wx.svg.SVGimage` class for a derived implementation that adds
   functionality for integrating with wxPython.

   .. method:: Rasterize(self, float tx=0.0, float ty=0.0, float scale=1.0, int width=-1, int height=-1, int stride=-1) -> bytes

      Renders the SVG image to a ``bytes`` object as a series of RGBA values.
      
      :param float `tx`: Image horizontal offset (applied after scaling)
      :param float `ty`: Image vertical offset (applied after scaling)
      :param float `scale`: Image scale
      :param int `width`: width of the image to render, defaults to width from the SVG file
      :param int `height`: height of the image to render, defaults to height from the SVG file
      :param int `stride`: number of bytes per scan line in the destination buffer, typically ``width * 4``
      
      :returns: A bytearray object containing the raw RGBA pixel color values


   .. method:: RasterizeToBuffer(self, buf, float tx=0.0, float ty=0.0, float scale=1.0, int width=-1, int height=-1, int stride=-1) -> bytes

      Renders the SVG image to an existing buffer as a series of RGBA values.
      
      The buffer object must support the Python buffer-protocol, be writable,
      and be at least ``width * height * 4`` bytes long. Possibilities include
      bytearrays, memoryviews, numpy arrays, etc.
      
      :param `buf`: An object supporting the buffer protocol where the RGBA bytes will be written
      :param float `tx`: Image horizontal offset (applied after scaling)
      :param float `ty`: Image vertical offset (applied after scaling)
      :param float `scale`: Image scale
      :param int `width`: width of the image to render, defaults to width from the SVG file
      :param int `height`: height of the image to render, defaults to height from the SVG file
      :param int `stride`: number of bytes per scan line in the destination buffer, typically ``width * 4``


   .. attribute:: height

      SVGimageBase.height: float
      
      Returns the height of the SVG image


   .. attribute:: shapes

      A generator that iterates over the :class:`SVGshape` objects that comprise the SVG image


   .. attribute:: width

      SVGimageBase.width: float
      
      Returns the width of the SVG image
