How can I read an image from the clipboard? I'm able to read text from the clipboard using wx.Clipboard, but not images.

Is it possible to read images with wx.Clipboard? If not, is there another way?

I'm using Python 2.5 and Windows Vista 64-bit.

The following works for me (tested on Mac OSX)

import wx
class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, -1, 'test frame',size=(790, 524))
        self.Bind(wx.EVT_LEFT_DOWN, self.OnClick)
        self.Bind(wx.EVT_PAINT, self.OnPaint)
        self.clip = wx.Clipboard()
        self.x = wx.BitmapDataObject()
        self.bmp = None

    def OnClick(self, evt):
        self.clip.Open()
        self.clip.GetData(self.x)
        self.clip.Close()
        self.bmp = self.x.GetBitmap()
        self.Refresh()

    def OnPaint(self, evt):
        if self.bmp:
            dc = wx.PaintDC(self)
            dc.DrawBitmap(self.bmp, 20, 20, True)

if __name__ == '__main__':
    app = wx.App()
    frame = MyFrame()
    frame.Show()
    app.MainLoop()

To use this, I run it and when the frame comes up I copy an image using another program and then click in the wx frame, which then causes the copied image to be drawn within it.

Python Imaging Library has an ImageGrab module that can do just that. This works on windows only.
