什么是非注册com，举个例子：DirectX9, DirectX10, DirectX11,DirectX12那种非注册com只能根据c++接口定义调用，不能用易语言"对象".查看()，cha询到所有方法，只能自己手动实现


这个代码是编码器，还有一个方法是解码器（没实现），两个相互配合就可以做图片格式转换其他格式就不搞了，太麻烦了，默认格式是：bmp(32位RGBA)
这种非注册com组件，用易语言的对象没法调用，只是提供一个方法
这种com接口结构怎么算呢，比如：A继承B
c++里面是
struct B {
   a: int
   b: int
}


struct A: B {
   a: int
   b: int
   c: int
}
易语言里面就这么写  (谁是父类，谁就塞前面，b是a的父类)
{
  b_a
  b_b
  a_a
  a_b
  a_c
}

‘--------------这里可以修改图片格式----------------

不知道少了哪，这里不显示了

HEX解码，就是HEX到字节集

易语言自带的对象确实不好用。
有些东西还得自己造轮子前段时间我用易语言的对象调用“Quartz”死活不行
后 ...

这个还好，有函数信息，不像WIC，只有C的抽象接口
