Camera.setDisplayOrientation works for me, I could never seem to get any 
rotation stuff to work that I tried to set using the Camera.Parameters.

2012-10-22 Thread Haris

I don't know why it's not worked with me. If I set orientation as portrait 
in manifest file I am getting 90 degree rotated image in my preview. But in 
the case of landscape orientation I am getting normal image in my preview 
while my phone orientation is portrait I know it is 90 degree rotated from 
landscape ,  and while saving or drawing  to a canvas I am getting 90 
degree rotated image. For this issue I just rotated my image 90 degree 
backward. I thought it is better to set the orientation correctly rather 
than rotating the image after capture.

Have you tried you application on any other phone. As you are accessing 
setparameter/getparameter; which is more specific with your hardware 
support. 
Have you tried any android application from Google play which 
behaves the way you would like. Confirm whether Phone provides the 
functionality or not

I'm assuming that you have some specific reason for wanting to use
portrait, where "normal" camera orientation is landscape?  In every
camera I've seen, used, or read about, the normal orientation is
landscape.  If you want portrait, you have to rotate the camera.
I recall reading somewhere in the developer's guide docs on the
camera that (as with 35mm and DSLR cameras) the Android camera's
normal orientation is landscape.  You CAN change that in java,
if you want to, though (but why would you?  if the user wants
to rotate the camera for a portrait-oriented shot, they'll
just rotate the device)

Re: [android-developers] Re: Android camera orientation problem

2012-10-23 Thread Adam Ratana

Haris, take a look a this:

http://developer.android.com/reference/android/hardware/Camera.html#setDisplayOrientation(int)

This is for API 8 (2.2+) devices.  I've found that there's no reliable way 
to guarantee this to work on 2.1 devices by setting the camera parameters 
the way you are now, some just won't do it.

I've just spent quite a bit of my spare time working on implementing a 
portrait mode activity option for the camera preview - to answer Spooky's 
question, the main reason one might do this is because it goes well with 
the UI/UX of the application (specifically the other activities which share 
a common UI), and the application for the camera activity is augmented 
reality, and for most devices that I've had experience with, the sensors 
seem to be most accurate when the phone is held in portrait - though this 
can clearly vary.  It also was desired to have a working portrait mode 
version of the camera activity, instead of forcing the user to then change 
the way they were holding the device.  Instagram is one massively popular 
application which does this as well (or at least, appears to do so), and I 
think it works well with their UI.

You can of course, take advantage of the above method to simply rotate the 
preview depending on the current orientation of the device - either 
portrait or landscape, and indeed have different UIs for either scenario if 
you wish.  Of course then choosing the optimal preview size for your 
orientation, taking into account status bars or full screen, etc, can then 
be tricky and yield different results for each.  The default camera app 
seems to rotate it's UI elements which is a pretty neat solution.  Rotating 
any preview frames or shots is the least of the worries here, that's 
relatively simple to do.

I plan on cleaning up and open sourcing a proof of concept project I built 
which does a bunch of things, including dealing with having a camera 
orientation the same as the device orientation, and rotating it when the 
device rotates, etc, since this seems a really painful thing.  I'll post 
back here when it's up, probably within a month.

Hi thanks all for your replays.. 

Yesterday I have checked some application from google play like 
pudding camera etc. and it's working perfectly. Even if I access the 
default camera from my application I am getting normal preview but while 
saving it is rotated. The reason why I need to use in portrait mode is that 
after capture I have to do some image processing algorithms on the image 
using opencv, and  on the JNI part it seems that  height of the image 
became width and width became height and all these because of the rotation. 
To avoid that confusion, -I know that not a big issue I just need to rotate 
the image 90 degree  backward-  I thought it is better to modify the camera 
orientation . Can any one give me a working source code for changing the 
camera orientation, may be it's my coding problem

Thanks

Haris, check the link I provided, this is code you can call which will make
the camera orientation the same as the activity orientation.  for instance
if you set the activity orientation to portrait, calling the method will
also rotate the camera preview --

http://developer.android.com/**reference/android/hardware/**Camera.html#**
setDisplayOrientation(int)

they provide some code here.  Note that any preview frames will not be
rotate, though.

"If you want to make the camera image show in the same orientation as the
display, you can use the following code."

public static void setCameraDisplayOrientation(Activity activity,
 int cameraId, android.hardware.Camera camera) {
 android.hardware.Camera.CameraInfo info =
 new android.hardware.Camera.CameraInfo();
 android.hardware.Camera.getCameraInfo(cameraId, info);
 int rotation = activity.getWindowManager().getDefaultDisplay()
 .getRotation();
 int degrees = 0;
 switch (rotation) {
 case Surface.ROTATION_0: degrees = 0; break;
 case Surface.ROTATION_90: degrees = 90; break;
 case Surface.ROTATION_180: degrees = 180; break;
 case Surface.ROTATION_270: degrees = 270; break;
 }

 int result;
 if (info.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
 result = (info.orientation + degrees) % 360;
 result = (360 - result) % 360;  // compensate the mirror
 } else {  // back-facing
 result = (info.orientation - degrees + 360) % 360;
 }
 camera.setDisplayOrientation(result);
 }

Ahhh, yes.  Good point.  I hadn't thought about that.
