How to skew in Unity with matrix values?
问题
我需要对Unity项目中的元素进行一些变换，使用我从XML文件中提取的矩阵数值：
<DOMBitmapInstance libraryItemName="Scene/Picture/CAM_U_cptgen_GEN_TOP_T1(4th_seat).png">
<matrix>
<Matrix a="0" b="1.66069030761719" c="-1.66069030761719" d="0" tx="178.5" ty="-673"/>
</matrix>
</DOMBitmapInstance>
我的问题是，如何倾斜我的图像，因为'a'和'd'应该是x和y的缩放，而'b'和'c'是y和x的倾斜。
我需要在Unity中显示图像并对其进行动画处理，因此这些值可能会更改。
到目前为止，我已提取了所有的值并已应用'a'和'd'。
提前感谢！
在项目的先前版本中，我曾在同一项目上工作，但是生成的不是源文件（如他们所说，计划已更改），它是在js中生成的，我可以轻松提取倾斜值，因为它是一个像'90'度这样的旋转值。但是对于同一项目，现在我有这些数值，我不太知道如何将它们应用到Unity Transform中。

I need to do some transform to elements in Unity for a project, with matrix values that I extract on a XML file :
<DOMBitmapInstance libraryItemName="Scene/Picture/CAM_U_cptgen_GEN_TOP_T1(4th_seat).png">
<matrix>
<Matrix a="0" b="1.66069030761719" c="-1.66069030761719" d="0" tx="178.5" ty="-673"/>
</matrix>
</DOMBitmapInstance>
My question is, how can I skew my image, because 'a' and 'd' are supposed to be for x and y scale, and 'b' and 'c' are for y and x skew.
I need to display images and to animate them in Unity, so this values can change.
For now on, I extract all values and already apply 'a' and 'd'.
Thanks in advance !
In a previous version of the project, I worked on the same project but generated, not the source file (plans have changed like they say) and It was generated in js, and I could easily extract Skew value because It was a rotation value like '90' degrees. But for the same project, now I have this numbers I don't really know how to apply them into a Unity Transform.

所以，我找到了一个解决方案，如果有人将来需要做和我一样的事情，我会在这里发布。
public void SetSkew(float b, float c)
{
float a = elementObject.transform.localScale.x;
elementObject.GetComponent<RectTransform>().localRotation = Quaternion.Euler(0, 0, Mathf.Atan2(c, a) * Mathf.Rad2Deg);
}

So, I found a solution, I'll post here if someone needs one day to do the same as me.
public void SetSkew(float b, float c)
{
float a = elementObject.transform.localScale.x;
elementObject.GetComponent<RectTransform>().localRotation = Quaternion.Euler(0, 0, Mathf.Atan2(c, a) * Mathf.Rad2Deg);
}
