Load svg into Pygame image using pynanosvg (https://github.com/ethanhs/pynanosvg)

svgsurf.py

from svg import Parser, Rasterizer

    """Returns Pygame Image object from rasterized SVG

    svg = Parser.parse_file(filename)
    tx, ty = 0, 0
    if size is None:
        w, h = svg.width, svg.height
    else:

    return image


if __name__ == '__main__':
    pygame.init()
    screen = pygame.display.set_mode((480, 420))
    img = load_svg('img.svg')
    while True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                sys.exit()
        screen.fill(pygame.colordict.THECOLORS['white'])
        screen.blit(img, img.get_rect())
        pygame.display.flip()

This was not working for me - with a plain object (opaque yellow star, transparent background, no border) on a 50% grey background -

I get a very-translucent yelowish star with a cyan-coloured-ish translucent border.

Changing the pygame.image.frombuffer() 'ARGB' to 'RGBA' fixes this for me. Using Pygame 1.9.4 on Python 3.6.7 on Linux.

Bad Star ARGB
Good Star RGBA

Star SVG: (I can't upload it, computer says "No")

Same issue with me. Changing it the RGBA fixed it. THanks @kt-- I would have never solved this without your comment :)

Thanks guys. The ARGB was working for couple my images so I assumed it's common setting.

I also had the same issue, maybe it's time to update the gist?

OK, I updated the gist. Note that pynanosvg has been archived and is no longer maintained so please use with caution.

Still seems to work fine for me, although it may have issues with using SVG's made in illustrator
