Triangle class

This page explains the Triangle class.

What class is this?

The Triangle class creates a triangle vector graphics object.

Basic usage

The Triangle class constructor requires the x1, y1, x2, y2, x3, and y3 arguments.

The x1 and y1 arguments are the first vertex’s coordinates.

Similarly, the x2 and y2 are the second vertex’s coordinates, and the x3 and y3 are the third.

The constructor also accepts each style’s argument, such as the fill_color.

import apysc as ap

ap.Stage(
    background_color=ap.Color("#333"),
    stage_width=150,
    stage_height=150,
    stage_elem_id="stage",
)
triangle: ap.Triangle = ap.Triangle(
    x1=75,
    y1=50,
    x2=50,
    y2=100,
    x3=100,
    y3=100,
    fill_color=ap.Color("#0af"),
)

Note of the draw_triangle interface

you can also create a triangle instance with the draw_triangle interface.
