phoenix_title wx.SVGBitmapHandler

Abstract base class for handling bitmaps inside a wx.SVGFileDC.

To use it you need to derive a new class from it and override ProcessBitmap to generate a properly a formed SVG image element (see http://www.w3.org/TR/SVG/struct.html#ImageElement).

Two example bitmap handlers are provided in /dcsvg.h . The first (default) handler will create PNG files in the same folder as the SVG file and uses links to them in the SVG. The second handler ( wx.SVGBitmapEmbedHandler) will embed the PNG image in the SVG file using base 64 encoding.

The handler can be changed by calling wx.SVGFileDC.SetBitmapHandler .

New in version 4.1/wxWidgets-3.1.0.

class wx.SVGBitmapHandler(object)

Abstract base class for handling bitmaps inside a SVGFileDC.


Methods

ProcessBitmap(self, bitmap, x, y, stream)

Writes the bitmap representation as SVG to the given stream.

The XML generated by this function will be inserted into the SVG file inline with the XML generated by the main wx.SVGFileDC class so it is important that the XML is properly formed.

Parameters
  • bitmap (wx.Bitmap) – A valid bitmap to add to SVG.

  • x (int) – Horizontal position of the bitmap.

  • y (int) – Vertical position of the bitmap.

  • stream (wx.OutputStream) – The stream to write SVG contents to.

Return type

bool
