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.
- Parameters:
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.
color_index (int) – Initial color_index to use when selecting color from the palette.
Hide the circle or not.
- pixel_shader: 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.
- Parameters:
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.
color_index (int) – Initial color_index to use when selecting color from the palette.
Hide the polygon or not.
- pixel_shader: 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
- Parameters:
pixel_shader (Union[ColorConverter,Palette]) – The pixel shader that produces colors from values
width (int) – The number of pixels wide
height (int) – The number of pixels high
x (int) – Initial x position of the top left corner.
y (int) – Initial y position of the top left corner.
color_index (int) – Initial color_index to use when selecting color from the palette.
Hide the rectangle or not.
- pixel_shader: displayio.ColorConverter | displayio.Palette
The pixel shader of the rectangle.
