How can I create a wxBitmap from png data already in memory without
having to write it to a file and then loading it?

Thanks

See the ImageFromStream sample in the demo.

Thanks. I think I should have looked at the demos before asking.

copied from the demo:

data = open(opj('bitmaps/image.png'), "rb").read()
stream = cStringIO.StringIO(data)
bmp = wx.BitmapFromImage(wx.ImageFromStream(stream))

That's *much* too complicated:

bmp = wx.Image( opj('bitmaps/image.png'),
wx.BITMAP_TYPE_ANY ).ConvertToBitmap()

Done ! There's no need for all that conversion nonsense

Do you one better :wink:

bmp = wx.Bitmap(path_to_file)

He wanted to be able to load it from a stream of already in memory
data though so the use of ImageFromStream would still be necessary for
that use case.
