setTransform () for SurfaceView

Question

When recording via TextureView to the screen is not mirrored used setTransform () method:

Matrix txform = new Matrix();
mTextureView.getTransform(txform);
txform.setScale((float) newWidth / viewWidth, (float) newHeight / viewHeight);
txform.postTranslate(xoff, yoff);
mTextureView.setTransform(txform);

And in my case I use SurfaceView instead TextureView and it turns out there is this method ...

Question: What should I do in order to mirror does not reflect, and what to use instead setTransform ()?

为了在 Y 轴上进行镜像，请使用以下命令：

txform.setScale(-(float) newWidth / viewWidth, (float) newHeight / viewHeight, viewWidth / 2.f , 0);
