Question

我正在创建的PIL图像有问题。似乎灰色背景的边框边缘采用在背景顶部绘制的椭圆的颜色。

首先，我使用辅助功能通过使用抗锯齿功能使椭圆看起来更平滑。但是，我认为此辅助功能中的蒙版引起了一个问题，即它在灰色背景的每个角上都留下了一个很小的（绿色）轮廓。

对于我的角落，我正在使用另一个帮助器函数来创建它们。也许这两个功能都有些冲突，但我不太确定。

这就是我想要做的：

def draw_ellipse(image, bounds, width=1, outline='white', antialias=4):
    """Improved ellipse drawing function, based on PIL.ImageDraw."""

    # Use a single channel image (mode='L') as mask.
    #The size of the mask can be increased relative to the imput image
    # to get smoother looking results. 
    mask = Image.new(size=[int(dim * antialias) for dim in image.size], mode='L', color='black')
    draw = ImageDraw.Draw(mask)

    # draw outer shape in white (color) and inner shape in black (transparent)
    for offset, fill in ( -7, 'white' ), ( width, 'black' ):
        left, top = [(value + offset) * antialias for value in bounds[:2]]
        right, bottom = [(value - offset) * antialias for value in bounds[2:]]
        draw.ellipse([left, top, right, bottom], fill=fill)

    # downsample the mask using PIL.Image.LANCZOS 
    # (a high-quality downsampling filter).
    mask = mask.resize(image.size, Image.LANCZOS)
    # paste outline color to input image through the mask
    image.paste(outline, mask=mask

def add_corners(im, rad):
    circle = Image.new('L', (rad * 2, rad * 2), 0)
    draw = ImageDraw.Draw(circle)
    draw.ellipse((0, 0, rad * 2, rad * 2), fill=255)
    alpha = Image.new('L', im.size, 255)
    w, h = im.size
    alpha.paste(circle.crop((0, 0, rad, rad)), (0, 0))
    alpha.paste(circle.crop((0, rad, rad, rad * 2)), (0, h - rad))
    alpha.paste(circle.crop((rad, 0, rad * 2, rad)), (w - rad, 0))
    alpha.paste(circle.crop((rad, rad, rad * 3, rad * 3)), (w - rad, h - rad))
    im.putalpha(alpha)
    return im

    #Grey background
    im = Image.new("RGBA", (900, 296), (44, 44, 44, 255))
    #Add some corners
    im = add_corners(im, 50) 
    im_draw = ImageDraw.Draw(im)


    #Green Ellipse
    ellipse_box = [55, 37, 107 + 48 + 46, 103 + 80]
    draw_ellipse(im, ellipse_box, width=20, outline=(52, 235, 52))

    im.save("image.png")

输出：

Answer 1

    int[] random_numbers = {10, 30, 44, 21, 51, 21, 61, 24, 14}
    int array_length = random_numbers.Length;
    for (int i = 0; i < array_length; i++){
        if(i == array_length - 1){
              Console.Write($"{random_numbers[i]}\n");
        } else{
              Console.Write($"{random_numbers[i]}, ");
         }
     }

这部分代码应放在

之后

#SingleInstance force
#warn

SetTimer, HN, 2500
return

r::Reload
x::ExitApp

HN:
If WinActive("ahk_class Notepad")
WinSet, Style, -0xC00000, A
return

这可以解决问题。
