rotationMatrix, scaleMatrix, translationMatrix compute the transformation matrix identityMatrix return a 4 x 4 identity matrix projectDown a 3D to 2D projection down a vector 还有一个函数 GramSchmidt,主要供内部使用:它对 3x3 矩阵进行 Gram-Schmidt 正交化,并对其在 cylinder3d 中使用进行了一些专门化。
包路径:org.geotools.referencing.operation.matrix.XAffineTransform类名称:XAffineTransform方法名:getRotation XAffineTransform.getRotation介绍 [英]Returns an estimation of the rotation angle in radians. This method assumes that the specified affine transform is built from arbitrary translations, scales or ...

使用int rotation = mActivity.getWindowManager().getDefaultDisplay().getRotation();可以获取屏幕旋转的方向,程序员大本营,技术文章内容聚合第一站。
I have similiar problem, trying to get rotation/transformation matrix of kGroupArt object. As documentation for AITransformArtSuite::TransformArt says: Text art, raster art, and placed art objects have associated transformation matrices. Functions such as AIRasterSuite::...
Transformation and Scene, Node, Scene Graph– Scene objects are represented by Nodes on the scene graph. So, this section explains how transformation (translation, rotation, scale) of the scene is done, scene compositions, scene objects and scene graphs manipulation & its traversing. ...

A page may have a rotation or translation associated with it and in this case (0, 0) may no longer correspond to the bottom left corner of the page relative to the viewer. For example here is the same page as above but rotated 90 degrees clockwise. Notice how the coordinates have all...
