vectorio – Lightweight 2D shapes for displays¶
The vectorio module provide simple filled drawing primitives for
use with displayio.
group = displayio.Group()
palette = displayio.Palette(1)
palette[0] = 0x125690
circle = vectorio.Circle(pixel_shader=palette, radius=25, x=70, y=40)
group.append(circle)
rectangle = vectorio.Rectangle(pixel_shader=palette, width=40, height=30, x=55, y=45)
group.append(rectangle)
points=[(5, 5), (100, 20), (20, 20), (20, 100)]
polygon = vectorio.Polygon(pixel_shader=palette, points=points, x=0, y=0)
group.append(polygon)
Available on these boards
- class vectorio.Circle(pixel_shader: displayio.ColorConverter | displayio.Palette, radius: int, x: int, y: int)¶
Circle is positioned on screen by its center point.
- Paramètres:
pixel_shader (Union[ColorConverter,Palette]) – The pixel shader that produces colors from values
radius (int) – The radius of the circle in pixels
x (int) – Initial x position of the axis.
y (int) – Initial y position of the axis.
- radius :int¶
The radius of the circle in pixels.
- x :int¶
X position of the center point of the circle in the parent.
- y :int¶
Y position of the center point of the circle in the parent.
- location :Tuple[int, int]¶
(X,Y) position of the center point of the circle in the parent.
- pixel_shader :Union[displayio.ColorConverter, displayio.Palette]¶
The pixel shader of the circle.
- class vectorio.Polygon(pixel_shader: displayio.ColorConverter | displayio.Palette, points: List[Tuple[int, int]], x: int, y: int)¶
Represents a closed shape by ordered vertices. The path will be treated as “closed”, the last point will connect to the first point.
- Paramètres:
pixel_shader (Union[ColorConverter,Palette]) – The pixel shader that produces colors from values
x (int) – Initial screen x position of the 0,0 origin in the points list.
y (int) – Initial screen y position of the 0,0 origin in the points list.
- points :List[Tuple[int, int]]¶
Vertices for the polygon.
- x :int¶
X position of the 0,0 origin in the points list.
- y :int¶
Y position of the 0,0 origin in the points list.
- location :Tuple[int, int]¶
(X,Y) position of the 0,0 origin in the points list.
- pixel_shader :Union[displayio.ColorConverter, displayio.Palette]¶
The pixel shader of the polygon.
- class vectorio.Rectangle(pixel_shader: displayio.ColorConverter | displayio.Palette, width: int, height: int, x: int, y: int)¶
Represents a rectangle by defining its bounds
- Paramètres:
- x :int¶
X position of the top left corner of the rectangle in the parent.
- y :int¶
Y position of the top left corner of the rectangle in the parent.
- location :Tuple[int, int]¶
(X,Y) position of the top left corner of the rectangle in the parent.
- pixel_shader :Union[displayio.ColorConverter, displayio.Palette]¶
The pixel shader of the rectangle.
