pub trait MaskedDrawable<const W: usize, const H: usize>: Drawable<Output = ()> {
// Required method
fn draw_masked<const MASK_N: usize, D>(

}Expand description
Draws a fixed RGB565 image through a matching binary mask.
This image-specific counterpart to
Drawable
is implemented for both an
Image565Fixed and the positioned value returned by
Image565Fixed::at. The W and H const arguments require the image and
MaskFixed dimensions to match at compile time. It is intentionally not
implemented for arbitrary Drawable types, whose pixels might not
correspond to a fixed, row-major mask.
Import this trait to make draw_masked
available. See the visual MaskFixed example, which draws an
opaque image beside its positioned, masked result.
Required Methods§
Sourcefn draw_masked<const MASK_N: usize, D>(
&self,
mask: &MaskFixed<W, H, MASK_N>,
target: &mut D,
) -> Result<(), D::Error>where
D: DrawTarget<Color = Self::Color>,
fn draw_masked<const MASK_N: usize, D>(
&self,
mask: &MaskFixed<W, H, MASK_N>,
target: &mut D,
) -> Result<(), D::Error>where
D: DrawTarget<Color = Self::Color>,
Draws the image, skipping pixels whose corresponding mask bits are clear.
An Image565Fixed draws at (0, 0). The value returned by
Image565Fixed::at draws at the supplied position. See the visual
MaskFixed example for the masked output.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
