Write image to Windows clipboard in python with PIL and win32clipboard?

Question

I'm trying to open an image file and copy the image to the Windows clipboard. Is there a way to fix this:

import win32clipboard
from PIL import Image

def send_to_clipboard(clip_type, data): 
    win32clipboard.OpenClipboard()
    win32clipboard.EmptyClipboard()
    win32clipboard.SetClipboardData(clip_type, data) 
    win32clipboard.CloseClipboard()

clip_type = win32clipboard.CF_BITMAP
filepath = 'c:\\temp\\image.jpg'

im = Image.open(filepath) 
data = im.tobitmap() # fails with valueerror: not a bitmap
# data = im.tostring() runs, but receiving programs can't read the results
send_to_clipboard(clip_type, data)

I could install PythonMagick, etc., but would prefer not installing yet another library for a one-off program

Answer 1

from cStringIO import StringIO
import win32clipboard
from PIL import Image

def send_to_clipboard(clip_type, data):
    win32clipboard.OpenClipboard()
    win32clipboard.EmptyClipboard()
    win32clipboard.SetClipboardData(clip_type, data)
    win32clipboard.CloseClipboard()

filepath = 'image.jpg'
image = Image.open(filepath)

output = StringIO()
image.convert("RGB").save(output, "BMP")
data = output.getvalue()[14:]
output.close()

send_to_clipboard(win32clipboard.CF_DIB, data)
