def draw():
    for _ in range(10):
        py5.rect(py5.random_int(py5.width), py5.random_int(py5.height), 10, 10)
    py5.save_frame('/tmp/random_squares_####.jpg')

Description

Save the current frame as an image. This method uses the Python library Pillow to write the image, so it can save images in any format that that library supports.

Use the drop_alpha parameter to drop the alpha channel from the image. This defaults to True. Some image formats such as JPG do not support alpha channels, and Pillow will throw an error if you try to save an image with the alpha channel in that format.

The use_thread parameter will save the image in a separate Python thread. This improves performance by returning before the image has actually been written to the file.

This method is the same as save() except it will replace a sequence of # symbols in the filename parameter with the frame number. This is useful when saving an image sequence for a running animation. The first frame number will be 1.

Syntax

save_frame(filename: Union[str, Path, BytesIO], *, format: str = None, drop_alpha: bool = True, use_thread: bool = False, **params) -> None

Parameters

  • drop_alpha: bool = True - remove the alpha channel when saving the image

  • filename: Union[str, Path, BytesIO] - output filename

  • format: str = None - image format, if not determined from filename extension

  • params: - keyword arguments to pass to the PIL.Image save method

  • use_thread: bool = False - write file in separate thread
