Function Documentation

find_supported_scaling_factor()

tuple[int, int] | None homeassistant.components.camera.img_util.find_supported_scaling_factor	(	int	current_width,
		int	current_height,
		int	target_width,
		int	target_height
	)

Find a supported scaling factor to scale the image.

If there is no exact match, we use one size up to ensure
the image remains crisp.

scale_jpeg_camera_image()

bytes homeassistant.components.camera.img_util.scale_jpeg_camera_image	(	Image	cam_image,
		int	width,
		int	height
	)
