Question Convert Screen Capture to base64

I was wondering how do you convert a screen capture of the running scene to base64 and put the base64 data into a file?

Here is a sample script that will save the raw image data of the screen to a base64 encoded file when the spacebar is pressed:
import viz
import viztask
import base64


model = viz.addChild('maze.osgb')

def SaveScreenTask():

	while True:

		# Wait for key press
		yield viztask.waitKeyDown(' ')

		# Capture screen to texture
		texture = viz.addBlankTexture([1,1])

		# Wait a frame for image to be captured
		yield viztask.waitFrame(1)

		# Save raw texture data to base64 encoded buffer
		data = base64.b64encode(texture.saveToBuffer('<raw>'))

		# Save data to file
		with open('screen_data', 'wb') as f:

		# Remove texture

viztask.schedule( SaveScreenTask() )
