Hi I am trying to use the camera to capture an image in one of my application. What is special is that I need a square preview area (and picture in the end). I tried defining the size of both picture and preview to 1:1 pixel ratios, but nothing seams to work. No matter what I does the picture looks "squashed" on a square.
Anyone who has any idea about how to resolve this?
code:
public class AddFromCameraActivity extends Activity implements SurfaceHolder.Callback {
private Camera mCamera;
private Parameters mParameters;
private SurfaceView mCameraPreview;
private SurfaceHolder mSurfaceHolder;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.addimagefromcameramain);
initialise();
//Testing area
mCamera = Camera.open();
mParameters = mCamera.getParameters();
mParameters.setFlashMode(Camera.Parameters.FLASH_MODE_AUTO);
mParameters.setFocusMode(Camera.Parameters.FOCUS_MODE_AUTO);
mParameters.setJpegQuality(50);
mParameters.setJpegThumbnailQuality(50);
mParameters.setPictureSize(1024, 1024);
//mParameters.setPreviewFormat(ImageFormat.JPEG);
mParameters.setJpegThumbnailSize(256, 256);
mParameters.setPreviewSize(500, 500);
mCamera.setParameters(mParameters);
}
private void initialise()
{
mCameraPreview = (SurfaceView)findViewById(R.id.cameraSurfaceView);
mSurfaceHolder = mCameraPreview.getHolder();
mSurfaceHolder.addCallback(this);
mSurfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
mSurfaceHolder.setFixedSize(500, 500);
}
@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width,
int height) {
}
@Override
public void surfaceCreated(SurfaceHolder holder) {
try {
mCamera.setPreviewDisplay(mSurfaceHolder);
mCamera.startPreview();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
public void surfaceDestroyed(SurfaceHolder holder) {
mCamera.stopPreview();
mCamera.release();
}
@Override
public void onPause()
{
mCamera.release();
}
}
thanks
