我現在面臨的廢棄警告如何用SVG圖標創建一個wxPython按鈕？
wxPyDeprecationWarning: Call to deprecated item ImageFromStream. Use :class:`Image` instead.
svgimg = wx.ImageFromStream(StringIO.StringIO(svgpng),wx.BITMAP_TYPE_PNG)
wxPyDeprecationWarning: Call to deprecated item BitmapFromImage. Use :class:`wx.Bitmap` instead
svgbmp = wx.BitmapFromImage(svgimg)
爲
def getBmpFromSvg(self,svgxml, width, height):

svgpng = cairosvg.svg2png(svgxml)
svgimg = wx.ImageFromStream(StringIO.StringIO(svgpng),wx.BITMAP_TYPE_PNG)
svgimg = svgimg.Scale(width, height, wx.IMAGE_QUALITY_HIGH)
svgbmp = wx.BitmapFromImage(svgimg)
return svgbmp
playButtonImg = self.getBmpFromSvg(resource_string("[name]", os.path.join("resources", "icons", 'play-button.svg')), icon_size_default, icon_size_default)
self.playButton = buttons.GenBitmapButton(self.videoPanel, bitmap=playButtonImg, name="play")
我似乎還沒有找到如何從Icon's documentation創建一個SVG圖標按鈕信息（指出圖標應該是位圖，在SVG時間周圍似乎有點過時）和the icons overview。 Button's documentation也只提及位圖。
即使我必須使用位圖，我想消除棄用警告。
我使用的是從Ubuntu 16.10源代碼構建的Phoenix 9b743cf3（它們未能使用git標籤）。
