Polyscope includes simple functionality for saving screenshots from the current camera view to disk. The ImGUI interface windows will be automatically hidden when taking a screenshot.

Screenshots can be taken manually by pressing the [screenshot] button in the options GUI window, or programmatically using the functions below. Clicking the GUI button generates a numbered screenshot file in the current directory; the arrow to the side of the button can be used to adjust file format and transparency settings for these screenshots.

It is not necessary to call show() before taking screenshots. You can set up you scene and programmatically configure the camera view, then call screenshot() to save a rendered image to disk, all without any user interaction.

Example: Register a mesh, position the camera, and take a screenshot

import polyscope as ps

# Initialize

# Register a mesh
verts = # ... your data ...
faces = # ... your data ...
ps_mesh = ps.register_surface_mesh("my mesh", verts, faces)

# Position the camera
ps.look_at((0., 0., 5.), (1., 1., 1.))

# Adjust some screenshot default settings if you'd like

# Take a screenshot
# It will be written to your current directory as screenshot_000000.jpg, etc

screenshot(filename=None, transparent_bg=True)

Saves a screenshot to the path given as filename, with format inferred from the file extension.

The extension should be one of .png, or .jpg.

If no name is is given, screenshots are saved to the current directory, with file named like screenshot_000000.png numbered automatically in increasing order. The numbering is reset to 0 for each run of the program; existing files will be silently overwritten.

If transparent_bg is true, the background will be rendered as transparent, and set as transparency alpha in the saved image if the file format supports it.

screenshot extension

Set the extension used when taking automatically-numbered screenshots, either with screenshot() or by clicking the GUI button.

The extension should be .png, or .jpg.
