Description: android.graphics.Camera可以对图像执行一些比较复杂的操作，诸如旋转与绽放，与Matrix可实现图像的倾斜。
个人总结Camera与Matrix的一些区别如下：
Camera的rotate()相关方法是指定某一维度上旋转指定的角度。
Matrix的rotate()相关方法实现的效果是顺时针旋转指定的角度；与Camera指定Z轴旋转效果相同，但方向相反。
Camera的translate()方法根据某一维度上视点的位移实现图像的缩放，与Matrix的scale()相关方法作用效果相似，只是Matrix的scale()相关方法是直接指定缩放比例。
Camera不支持倾斜操作，Matrix可以直接实现倾斜操作。-android.graphics.Camera Images can perform some of the more complex operations, such as rotation and bloom, and Matrix Figure
Like the tilt.
Personal summary of some of the differences in the Camera and Matrix are as follows:
Camera, rotate () related methods specify the angle of rotation specified in a dimension.
The Matrix, the rotate () related methods to achieve the effect clockwise rotation of the specified angle Camera specify the Z-axis has the same effect, but
The opposite direction.
Camera, the translate () method according to the displacement of a dimension point of view, image scaling and the scale of the Matrix () method
The effect is similar, only the scale () related to the Matrix approach is to directly specify the scaling.
Camera does not support the tilt, the Matrix can directly tilt operation. Platform: |
