WebOct 11, 2024 · QTransform 用于指定坐标系的 2D 转换 - 平移、缩放、扭曲（剪切）、旋转或投影坐标系。 绘制图形时，通常会使用。 QTransform 与 QMatrix 不同之处在于，它是一个真正的 3x3 矩阵，允许视角转换，QTransform 的 toAffine () 方法允许将 QTransform 转换到 QMatrix。 如果视角转换已在矩阵指定，则转换将导致数据丢失。 常用接口 translate … WebDefinition. Let X be an affine space over a field k, and V be its associated vector space. An affine transformation is a bijection f from X onto itself that is an affine map; this means that () = () well defines a linear map from V to V; here, as usual, the subtraction of two points denotes the free vector from the second one to the first one, and "well-defined" means … twilight xobor https://adwtrucks.com
