only.Expand description
Canvas which is drawable at the provided Point
(location) on the display.
Fields§
§top_left: Point
The top left offset where the CanvasAt
will be drawn to the display.
canvas: Size
The size of the CanvasAt
.
pixels: Box<[Option<C>]>
The pixels of the CanvasAt
.
Implementations§
source§impl<C: PixelColor> CanvasAt<C>
impl<C: PixelColor> CanvasAt<C>
sourcepub fn with_default_color(
top_left: Point,
canvas: Size,
default_color: C
) -> Self
pub fn with_default_color( top_left: Point, canvas: Size, default_color: C ) -> Self
sourcepub fn with_center(center: Point, canvas: Size) -> Self
pub fn with_center(center: Point, canvas: Size) -> Self
Create a new blank CanvasAt
with a set center on the display.
sourcepub fn crop(&self, area: &Rectangle) -> Option<CanvasAt<C>>
pub fn crop(&self, area: &Rectangle) -> Option<CanvasAt<C>>
Create a new cropped CanvasAt
.
This method takes into account the top left Point
of the area
you’d like to crop relative to the display.
If the width or height of the Rectangle
is 0
, this method will
return None
(see Rectangle::bottom_right()
)
