Method draw_image

lib/matplotlib/backend_bases.py:438–469

Draw an RGBA image. Parameters ---------- gc : `.GraphicsContextBase` A graphics context with clipping information. x : float The distance in physical units (i.e., dots or pixels) from the left hand side of the canvas.

(self, gc, x, y, im, transform=None)

        return 1.0

        Draw an RGBA image.

        Parameters
        ----------
        gc : `.GraphicsContextBase`
            A graphics context with clipping information.

        x : float
            The distance in physical units (i.e., dots or pixels) from the left
            hand side of the canvas.

        y : float
            The distance in physical units (i.e., dots or pixels) from the
            bottom side of the canvas.

        im : (N, M, 4) array of `numpy.uint8`
            An array of RGBA pixels.

        transform : `~matplotlib.transforms.Affine2DBase`
            If and only if the concrete backend is written such that
            `~.RendererBase.option_scale_image` returns ``True``, an affine
            transformation (i.e., an `.Affine2DBase`) *may* be passed to
            `~.RendererBase.draw_image`.  The translation vector of the
            transformation is given in physical units (i.e., dots or pixels).
            Note that the transformation does not override *x* and *y*,
            and has to be applied *before* translatingthe result by
            *x* and *y* (this can be accomplished by adding *x*
            and *y* to the translation vector defined by *transform*).
