In this article we will see how to create an SVG file using generativepy.

SVG files

SVG (Standard Vector Graphics) is a file format that stores a vector image. Vector images can be printed at any size without blurring or loss of detail.

SVG files can also be opened by most vector drawing programs (for example, Inkscape) and edited. This allows you to use generativepy to create an image, and then add finishing touches manually with a drawing program.

Creating an SVG

Creating an SVG file is very easy. It is exactly the same as creating a PNG file, except that you call make_svg instead of `make_image:

from generativepy.drawing import setup, make_svg
from generativepy.color import Color
from generativepy.geometry import Rectangle

def draw(ctx, pixel_width, pixel_height, frame_no, frame_count):

    setup(ctx, pixel_width, pixel_height, background=Color(0.4))

    color = Color(1, 0.5, 0)

    Rectangle(ctx).of_corner_size((100, 150), 250, 200).fill(color)

make_svg("rectangle-svg.svg", draw, 500, 400)

One thing to note is that the page size is just a nominal value. You can easily resize or scale the image in Inkscape.

This code is available on github in tutorial/getting-started/rectangle-svg.py.
