Save image as string

Hello,

is there any function to save an image to a string? I tried this:

import cStringIO
outputStream = cStringIO.StringIO()
img.SaveFile( wx.OutputStream(outputStream), wx.BITMAP_TYPE_PNG )

but it fails. Calling img.GetData() is not what I want because it returns the raw image data and not the image as saved to a file.

You might take a look at the img2py utility. You can read a little bit about it here: http://www.blog.pythonlibrary.org/?p=34

And here's the official docs: wxPython API Documentation — wxPython Phoenix 4.2.2 documentation

It's called SaveStream.

That did the trick, thank you. I must've overlooked it when I did dir(wx.Image).

Thanks, didn't think about looking at it.
