当没有以90度角绘制线时，线的表面不是完全平滑的

Question

我正在使用倾斜效果将图像旋转到一定角度，但是当图像旋转时，直线会变得有点不均匀（线条表面不平滑）。

以下是它的图像：

如何删除此内容？我不认为这是代码的问题。我猜它与GPU或类似的东西有关。

以下是代码：

public class TiltAnimation extends Animation {

    private static final String TAG = "com.fourmob.tilteffect.TiltAnimation";

    public static final int ROTATE_AXIS_X = 0;
    public static final int ROTATE_AXIS_Y = 1;

    private final float mCenterX;
    private final float mCenterY;

    private Camera mCamera;

    private final ArrayList<Rotation> mRotations = new ArrayList<Rotation>();

    public TiltAnimation(float fromDegrees, float toDegrees, float centerX, float centerY, int rotateAxe) {
        this(centerX, centerY);
        mRotations.add(new Rotation(rotateAxe, fromDegrees, toDegrees));
    }

    public TiltAnimation(float centerX, float centerY) {
        mCenterX = centerX;
        mCenterY = centerY;
    }

    public void addRotation(float fromDegrees, float toDegrees, int rotateAxe) {
        mRotations.add(new Rotation(rotateAxe, fromDegrees, toDegrees));
    }

    @Override
    public void initialize(int width, int height, int parentWidth, int parentHeight) {
        super.initialize(width, height, parentWidth, parentHeight);
        mCamera = new Camera();
    }

    @Override
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        final float centerX = mCenterX;
        final float centerY = mCenterY;

        final Matrix matrix = t.getMatrix();

        mCamera.save();

        for(Rotation rotation : mRotations) {
            Log.d(TAG, "rotation : " + rotation);
            float degrees = rotation.mFromDegrees + ((rotation.mToDegrees - rotation.mFromDegrees) * interpolatedTime);
            if(rotation.mRotateAxis == ROTATE_AXIS_X) {
                mCamera.rotateX(degrees);
            } else if(rotation.mRotateAxis == ROTATE_AXIS_Y) {
                mCamera.rotateY(degrees);
            }
        }

        mCamera.getMatrix(matrix);
        mCamera.restore();

        matrix.preTranslate(-centerX, -centerY);
        matrix.postTranslate(centerX, centerY);

    }

    public void addRotations(Rotation... rotations) {
        mRotations.addAll(Arrays.asList(rotations));
    }


    public static final class Rotation {
        int mRotateAxis;
        float mFromDegrees;
        float mToDegrees;

        public Rotation(int mAxis, float mFromDegrees, float mToDegrees) {
            this.mRotateAxis = mAxis;
            this.mFromDegrees = mFromDegrees;
            this.mToDegrees = mToDegrees;
        }

        @Override
        public String toString() {
            return "Rotation{" +
                    "mRotateAxis=" + (mRotateAxis == ROTATE_AXIS_X ? "X":"Y") +
                    ", mFromDegrees=" + mFromDegrees +
                    ", mToDegrees=" + mToDegrees +
                    '}';
        }
    }
}
