Square

The Square class draws a square.

There is also a square function that just creates a square as a new path.

Square class methods

The Square class inherits add, fill, stroke, fill_stroke, path, clip and other methods from Shape.

It has an additional method:

• of_corner_size

of_corner_size

Creates a square based on the position and size.

of_corner_size(corner, width)

square function

Adds a square as a new path, without the need to create a Square object in code.

square(ctx, corner, width, height)

Example

Here is some example code that draws squares using the class and the utility function. The full code can be found on github.

from generativepy.drawing import make_image, setup
from generativepy.color import Color
from generativepy.geometry import Square, square

'''
Create squares using the geometry module.
'''

def draw(ctx, width, height, frame_no, frame_count):
    setup(ctx, width, height, width=5, background=Color(0.8))

    # The square function is a convenience function that adds a square as a new the path.
    # You can fill or stroke it as you wish.
    square(ctx, (1, 1), 1)
    ctx.set_source_rgba(*Color(1, 0, 0))
    ctx.fill()

    # Square objects can be filled, stroked, filled and stroked.
    Square(ctx).of_corner_size((3, 1), 1).fill(Color(0, .5, 0))
    Square(ctx).of_corner_size((1, 3), 1).stroke(Color(0, .5, 0), 0.1)
    Square(ctx).of_corner_size((3, 3), 1).fill_stroke(Color(0, 0, 1), Color(0), 0.2)
