Add a Remote Screenshot

[53845714nF]

Add a Remote Screenshot Function this creates a screenshot like the normal screenshot, except that it outputs the image as Base64 String. It could be useful for example on embedded devices, where you do not want to save images on the device.

For an Example, use in Python:

session = ServerProxy('http://192.168.178.142:9000')

image_string = session.takeScreenshotRemote('mainWindow/header/burgerMenu')

print("Remote Image:" + str(image_string))

image_data = b64decode(image_string)

with open('burgerMenu.png', 'wb') as f:
    f.write(image_data)

You get:

Remote Image:iVBORw0KGgoAAAANSUhEUgAAADIAAAAyCAIAAACRXR/mAAAACXBIWXMAAA9hAAAPYQGoP6dpAAAAnklEQVRYhe3WMQrAIBBEUTek1xvruZJLeQPTS4oZUJxifi3xYRYxxhhJr+s04D+zmMxiMovJLCazmMxiMovpBtdFxJL9wOed6GmJstCfmHPe6pgKv+WJRFnobLXWluwHfgedLd9bKcmy0NmqtW51TPneYhJlobNVSlmyX+8dWeZ7i0mU5QuCySwms5jMYjKLySwmUdb9PO9pw0+ip/UB/cMlMpXl7ngAAAAASUVORK5CYII=

Which reflects in to this image:

There you can then see whether the component looks as it is supposed to.

I like the functionality, but am wondering about the "Remote" naming, which seems to be specific to your use case. However one could also use it in a GTest running locally, where the base64 string is just compared with an expected value. Then, nothing "remote" would be involved.

Could we rename it to something that more describes what it does, rather than how it could be used? Though I'm also not sure what a good name would be.... Maybe something like takeScreenshotAsString? or takeScreenshotAsBase64?

What do you think @53845714nF ?

Sorry that I am writing so late, I am a little ill.

That sounds fine to me, I can fully understand that.

Cool, then what about we go with takeScreenshotAsBase64? Could you do the renaming once you're fully recovered? Until then, "Gute Besserung"!

Thank you very much, I'm still not completely healthy, but I've got to work on it now. I think there are some viruses going around in Germany, so take care.

I pulled the branch to the current master branch, so it looks like there are 5 new commits, but there are actually only two new ones. The last one is the one where I renamed the function. It would be good if the PR became one commit, but I think GitHub does that automatically.
