Struct MaskFixed 

pub struct MaskFixed<const W: usize, const H: usize, const MASK_N: usize> {
    pub bits: [u8; MASK_N],
}

A packed binary visibility mask with one bit per image pixel.

Set bits are drawn and clear bits are transparent. Create a mask from an Image888Fixed with Image888Fixed::to_mask_magenta, then pass it to MaskedDrawable::draw_masked.

Example

Fields

bits: [u8; MASK_N]

Row-major visibility bits, least-significant bit first within each byte.

Implementations

impl<const W: usize, const H: usize, const MASK_N: usize> MaskFixed<W, H, MASK_N>

pub const fn is_set(&self, index: usize) -> bool

Returns whether the row-major pixel at index is visible.

See the MaskFixed example.
