圆枕蟒蛇

Question

我希望您能在枕头模块方面帮助我 我的问题是，当我尝试在im1中粘贴“ result.png”时，它会粘贴，但作为正方形，我想成为一个圆形。 备注>>'result.png'是圆形图像

    draw = ImageDraw.Draw(alpha)
    draw.pieslice([0, 0, h, w], 0, 360, fill=255)

    # Convert alpha Image to numpy array
    npAlpha = np.array(alpha)

    # Add alpha layer to RGB
    npImage = np.dstack((npImage, npAlpha))

    # Save with alpha
    Image.fromarray(npImage).save('result.png')
    im2_ = Image.open(r'C:\Users\SIDALI\PycharmProjects\Original\result.png')
    im2_.thumbnail(size, Image.ANTIALIAS)
    back_im = im1.copy()
    back_im.paste(im2_, (430, 98))
    back_im.save(r'C:\Users\SIDALI\PycharmProjects\Original\tests.png', quality=95)

    await ctx.send(file=(discord.File('tests.png')))
