Anti-aliasing with rounded_rectangle()

[ahmed4end]

the rounded edges is very sharp for a squircle! is there a way to use anti aliasing in the edges?

For the record, this was also discussed in #4765.

There isn't currently a direct way to do that. You could draw a larger image and then resize it using antialiasing.

from PIL import Image, ImageDraw
im = Image.new("RGBA", (200, 100), (0, 0, 0, 0))
draw = ImageDraw.Draw(im, "RGBA")
draw.rounded_rectangle((20, 20, 180, 80), 30, outline="#000")
im.save("normal.png")

for factor in range(2, 5):
    im = Image.new("RGBA", (factor*200, factor*100), (0, 0, 0, 0))
    draw = ImageDraw.Draw(im, "RGBA")
    draw.rounded_rectangle((factor*20, factor*20, factor*180, factor*80), factor*30, outline="#000", width=factor)
    im = im.resize((200, 100), Image.ANTIALIAS)
    im.save(str(factor)+".png")

• Normal
• 2
• 3
• 4

@radarhere this solution works for now, Is there any plans to implement anti-aliasing in general for the rounded rect and also the line func ?

[radarhere]

No active plans, no.

@radarhere I have a question I would really love to answer That I am trying to use code:

draw = ImageDraw.Draw (im)
draw.rounded_rectangle ((20, 20, 180, 80), outline = "# 000")

I have this error: AttributeError: 'ImageDraw' object has no attribute 'rounded_rectangle' thank you very much In the end what I want to do is something like this:

[radarhere]

What version of Pillow are you using?

from PIL import Image
print(Image.__version__)

rounded_rectangle() was only added in 8.2.0.

[radarhere]

@ahmed4end is there something new that you were after?

[ahmed4end]

@radarhere performance of generating a rounded rectangle that's bigger by number of times then resizing is not great on some projects

[radarhere]

on some projects

So it is ok on some projects? What is the difference between those?
