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?
:confused:

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:
Code:

import viz
import viztask
import base64

viz.go()

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])
                viz.window.screenCapture(texture)

                # 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(''))

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

                # Remove texture
                texture.remove()

viztask.schedule( SaveScreenTask() )
