Matrix4

一种被记录、可重放的 Matrix4 变换意图。

该类记录构造函数和会改变状态的方法调用，随后 Flet 会在 Flutter 中重放这些调用，为 matrix 构建出一个真实的 Matrix4。

属性

名称	类型	默认值	说明
ctor	_Matrix4Call	_Matrix4Call(name='identity'()	Recorded constructor call.
ops	list[_Matrix4Call]	[]	Ordered list of recorded mutating operations.

方法

名称	类型	默认值	说明
identity	'Matrix4'	—	Creates a matrix initialized with identity transform.
translation_values	'Matrix4'	—	Creates a matrix initialized with translation components.
diagonal3_values	'Matrix4'	—	Creates a matrix initialized with diagonal scale values.
rotation_z	'Matrix4'	—	Creates a matrix initialized with a z-axis rotation in radians.
skew_x	'Matrix4'	—	Creates a matrix initialized with x-axis skew in radians.
skew_y	'Matrix4'	—	Creates a matrix initialized with y-axis skew in radians.
translate	'Matrix4'	—	Appends translation operation.
scale	'Matrix4'	—	Appends scale operation. If only x is provided then uniform scale is used. If x and y are provided then 2D scale is used. If all three are provided then 3D scale is used.
rotate_z	'Matrix4'	—	Appends z-axis rotation operation in radians.
rotate_x	'Matrix4'	—	Appends x-axis rotation operation in radians.
rotate_y	'Matrix4'	—	Appends y-axis rotation operation in radians.
set_entry	'Matrix4'	—	Appends raw matrix entry mutation.
multiply	'Matrix4'	—	Appends multiplication by another recorded matrix.
