Question

我有一个用文本格式写的图像，我需要设置接近黑色到黑色的像素和接近白色的像素。

该文件使用ʜꜱʟ colour space，如下所示：

那么我（例如）如何替换上面的值（除了前2个数字（x,x:），它们给出像素坐标） by { {1}}使用vim或awkor使用其他脚本工具？

我正在考虑使用ʜꜱʟ值的light / last部分来确定是否需要替换（除了(0%,0%,0%) #000000 hsl(0%,0%,0%)）这一行，但我不知道该如何做此

你可以试试这个：

awk '
    BEGIN {
        black="(0%,0%,0%)  #000000  hsl(0%,0%,0%)"
        white="(0%,0%,100%)  #FFFFFF  hsl(0%,0%,100%)"
    }
    {
        line=$0
        coords=$1
        FS=","
        $0=$0
        match($4, "%")
        sub("%.*", "", $4)
        if ($4 < 25)
            printf("%s %s\n", coords, black)
        else if ($4 > 75)
            printf("%s %s\n", coords, white)
        else print line
        FS=" "
    }
' <img.txt

如果大于或小于？，如何替换写为字符串的浮点数？
