Screenshots

With Panopti you can capture screenshots directly from the interactive viewer (using the screenshot UI button), or programmatically like so:

import panopti
viewer = panopti.connect(server_url="http://localhost:8080", viewer_id='client')

# Frame your shot:
viewer.set_camera(
    position=(5.0, 2.5, 7.5),
    target=(0.0, 1.5, 0.0),
    projection_mode="orthographic"
)

# Take screenshot
img_arr = viewer.screenshot(filename='screenshot.png',
                            bg_color=(0.75, 0.3, 0.3)) # use bg_color=None for fully transparent background

viewer.hold()
