Class TextureCameraPreview

    • Method Summary

      Modifier and Type Method Description
      View getRootView() For testing purposes, should return the root view that was inflated into theparent during onCreateView.
      Class<SurfaceTexture> getOutputClass() Returns the type of the output returned by getOutput.
      SurfaceTexture getOutput() Returns the output surface object (for example a SurfaceHolderor a SurfaceTexture).
      boolean supportsCropping() Whether this preview implementation supports cropping.The base implementation does not, but it is strongly recommended to do so.
      void setDrawRotation(int drawRotation) Should be called after setStreamSize!Sets the rotation, if any, to be applied when drawing.

      • setDrawRotation

         void setDrawRotation(int drawRotation)

        Should be called after setStreamSize!Sets the rotation, if any, to be applied when drawing.Sometimes we don't need this:- In Camera1, the buffer producer sets our Surface size and rotates it based on the valuethat we pass to setDisplayOrientation,so the stream that comes in is already rotated (if we apply SurfaceTexture transform).- In Camera2, for android.view.SurfaceView based previews, apparently it just worksout of the box. The producer might be doing something similar.But in all the other Camera2 cases, we need to apply this rotation when drawing the surface.Seems that Camera1 can correctly rotate the stream/transform to VIEW,while Camera2, that does not have any rotation API, will only rotate to BASE.That's why in Camera2 this angle is set as the offset between BASE and VIEW.

        Parameters:
        drawRotation - the rotation in degrees
