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
wx.svg.SVGimage class for a derived implementation that adds
functionality for integrating with wxPython.

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.
tx (float) – Image horizontal offset (applied after scaling)
ty (float) – Image vertical offset (applied after scaling)
scale (float) – Image scale
width (int) – width of the image to render, defaults to width from the SVG file
height (int) – height of the image to render, defaults to height from the SVG file
stride (int) – number of bytes per scan line in the destination buffer, typically width * 4
A bytearray object containing the raw RGBA pixel color values
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.
buf – An object supporting the buffer protocol where the RGBA bytes will be written
tx (float) – Image horizontal offset (applied after scaling)
ty (float) – Image vertical offset (applied after scaling)
scale (float) – Image scale
width (int) – width of the image to render, defaults to width from the SVG file
height (int) – height of the image to render, defaults to height from the SVG file
stride (int) – number of bytes per scan line in the destination buffer, typically width * 4
height¶SVGimageBase.height: float
Returns the height of the SVG image
width¶SVGimageBase.width: float
Returns the width of the SVG image
