How Can You Draw More Detailed/smoother Images In Pygame?

I have been trying to get into the vector-styled art world and recently I've tried blitting a vector image using the .blit() method but when I do blit it, it comes out as pixelated

Solution 1:

Use pygame.transform.smoothscale instead of pygame.transform.scale:

img = pygame.transform.scale(img, (500,500))

img = pygame.transform.smoothscale(img, (500,500))

While pygame.transform.scale performs a fast scaling with the nearest pixel, pygame.transform.smoothscale scales a surface smoothly to any size with interpolation of the pixels.

For an even better result, you may want to switch to a vector graphic format such as SVG (Scalable Vector Graphics).
See the answers to the question SVG rendering in a PyGame application a nd the following minimal example:

import pygame

pygame.init()
window = pygame.display.set_mode((300, 300))
clock = pygame.time.Clock()

pygame_surface = pygame.image.load('Ice.svg')

run = True
while run:
    clock.tick(60)
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False

    window.fill((127, 127, 127))
    window.blit(pygame_surface, pygame_surface.get_rect(center = window.get_rect().center))
    pygame.display.flip()

pygame.quit()
exit()
