cannot use Adafruit_RGBMatrixQT with adafruit_led_animation

[mraveloarinjaka]

I wanted to use Adafruit_RGBMatrixQT to display some animations
adafruit_led_animation various animations expect a pixels object.
I wanted to use IS31FL3741_PixelBuf but it was missing the "write" method.
Please find below an adapter I wrote that allows to create a pixels object.
I would like to know:

• is being able to create an adafruit_pixelbuf.PixelBuf from Adafruit_RGBMatrixQT is a valid need?
• is an adapter such as the one below a relevant way to address this issue?

Thank you in advance for your feedback.

WIDTH = 13
HEIGHT = 9
LEDS_MAP = tuple(
    (
        address
        for x in range(WIDTH)
        for y in range(HEIGHT)
        for address in Adafruit_RGBMatrixQT.pixel_addrs(x, y)
    )
)


class RGBMatrixQTToPixelBufAdapter(Adafruit_RGBMatrixQT):
    """Additional properties so that Adafruit_RGBMatrixQT can be used with IS31FL3741_PixelBuf."""

    def __init__(
        self,
        i2c,
        allocate,
    ):
        super().__init__(i2c, allocate=allocate)

    def write(self, mapping, buffer):
        temp_buffer = FrameBuffer(
            buffer,
            WIDTH,
            HEIGHT,
            adafruit_framebuf.RGB888,
        )
        self.image(temp_buffer)
        self.show()


i2c = board.STEMMA_I2C()
is31 = RGBMatrixQTToPixelBufAdapter(i2c, allocate=adafruit_is31fl3741.PREFER_BUFFER)
# is31.set_led_scaling(0xFF)
is31.set_led_scaling(1)
is31.global_current = 0xFF
is31.enable = True
pixels = IS31FL3741_PixelBuf(is31, LEDS_MAP, init=False, auto_write=False)
