Backend: Pillow

Because bewegung is literally built around Pillow, the Pillow backend is by far the most simple one in the collection. For further details, please consult the documentation of Pillow.

from PIL import ImageDraw
from bewegung import Video

v = Video(width = 480, height = 270, seconds = 1.0)

@v.sequence()
class Foo:

    @v.layer(canvas = v.canvas(backend = 'pillow'))
    def bar(self, canvas): # a Pillow Image, mode RGBA

        draw = ImageDraw.Draw(canvas)
        draw.line(
            ((5, 5), (v.width - 5, v.height - 5)),
            fill = (255, 0, 0, 255), width = 3,
        )

        return canvas

v.reset()
v.render_frame(v.time(0))

Similar to PIL.Image.new, the function call v.canvas(backend = 'pillow') accepts the following additional keyword arguments:

• mode, by default 'RGBA'. If a format other than 'RGBA' is specified, the user has to convert the Image to 'RGBA' before returning it from the layer method.
• size, a tuple of width and height. Width and height of the video by default.
• color, a background color. Uses Pillow's default, black.
• width, mapped to size if provided together with height.
• height, mapped to size if provided together with width.
• background_color, mapped to color. Accepts bewegung.Color objects.
