README
这是一个处理纵横比的项目。虽然纵横比是一个简单的计算，但最近的“良好”纵横比不是，这正是这个项目的亮点。您可以输入任何尺寸集，实际的纵横比将以整数和小数形式计算，此外，您还将获得最近的“良好”纵横比，例如16:9，3:4等。作为额外奖励，还会计算与宽度相对应的黄金分割比。
以下是CLI输出的示例。
$ aspratio 768x634

- 附近的比率按与原始高度的差异顺序列出，差异最小者排在前面。
使用Composer全局安装
要能够在CLI中的任何目录使用aspratio，您可能需要全局安装此软件包。
composer global require aklump/aspect-ratio
请确保您的PATH中包含composer的bin目录。默认值为~/.composer/vendor/bin，但您可以通过运行composer global config bin-dir --absolute来检查需要使用的值。
要检查此设置，您必须打开~/.bash_profile（或~/.bashrc）；您正在寻找的行如下，如果您找不到，则需要添加它。
export PATH=~/.composer/vendor/bin:$PATH
快速入门

要确定尺寸集的纵横比、附近纵横比和黄金分割比，请在您的终端中键入以下内容；差异显示了附近比率高度变化的程度

微调
-
使用
--nearby和--variance来微调附近计算 -
--nearby返回从结果集中返回的附近值数量，按比例的宽度部分排序，从低到高。设置此值较低将减少更准确附近比率的数量，这些比率的分子较大。 -
--variance设置允许的最大差异。这可能是一个百分比或一个数字。此示例中首先显示的输入为百分比。因为此值低于默认值，所以比例值更准确，但比例不那么“良好”，也就是说数字更高。与默认差异值相比，默认差异值的比例更“良好”。$ aspratio 370x111 --variance=2% Type Ratio Dimensions Variance Variance % whole 10:3 370 x 111 0 0% decimal 3.333 370 x 111 0 0% nearby 10:3 370 x 111 0 0% nearby 27:8 370 x 110 -1 -0.9% nearby 33:10 370 x 112 1 0.9% nearby 37:11 370 x 110 -1 -0.9% nearby 43:13 370 x 112 1 0.9% nearby 47:14 370 x 110 -1 -0.9% nearby 17:5 370 x 109 -2 -1.8% nearby 23:7 370 x 113 2 1.8% nearby 36:11 370 x 113 2 1.8% nearby 44:13 370 x 109 -2 -1.8% golden 1.618 370 x 229 118 106.3% $ aspratio 370x111 --variance=80% Type Ratio Dimensions Variance Variance % whole 10:3 370 x 111 0 0% decimal 3.333 370 x 111 0 0% nearby 10:3 370 x 111 0 0% nearby 17:5 370 x 109 -2 -1.8% nearby 13:4 370 x 114 3 2.7% nearby 7:2 370 x 106 -5 -4.5% nearby 16:5 370 x 116 5 4.5% nearby 19:6 370 x 117 6 5.4% nearby 18:5 370 x 103 -8 -7.2% nearby 11:3 370 x 101 -10 -9% nearby 3:1 370 x 123 12 10.8% nearby 15:4 370 x 99 -12 -10.8% golden 1.618 370 x 229 118 106.3%
