Function drop_shadow_only

pub fn drop_shadow_only(
    offset: impl Into<Vector>,
    (sigma_x, sigma_y): (scalar, scalar),
    color: impl Into<Color4f>,
    color_space: impl Into<Option<ColorSpace>>,
    input: impl Into<Option<ImageFilter>>,
    crop_rect: impl Into<CropRect>,
) -> Option<ImageFilter>

Create a filter that renders a drop shadow, in exactly the same manner as ::DropShadow, except that the resulting image does not include the input content. This allows the shadow and input to be composed by a filter DAG in a more flexible manner.

• offset - The offset of the shadow.
• sigma_x - The blur radius for the shadow, along the X axis.
• sigma_y - The blur radius for the shadow, along the Y axis.
• color - The color of the drop shadow.
• color_space - The color space of the drop shadow color.
• input - The input filter, or will use the source bitmap if this is null.
• crop_rect - Optional rectangle that crops the input and output.
