I am capturing an image using MediaStore.ACTION_IMAGE_CAPTURE in
Android 2.1
Intent cameraintent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
File file = new File(Environment.getExternalStorageDirectory(),
"MyTestFile.jpg");
cameraintent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
outputFileUri = Uri.fromFile(file);
startActivityForResult(cameraintent, CAMERA_PIC_REQUEST);
Thereafter, I am using the following function to create a new bitmap,
scaled from the existing bitmap. But I am not getting the correct
value for image orientation. As per my logic when the image has been
captured in landscape mode I should get img_orient=0 & for portrait
mode I should getimg_orient=90. But I am getting 0 for both cases.
But when I am using the same function for an existing image from
inside the media gallery, it is returning correct values i.e 0 for
landscape & 90 for portrait. Can someone please tell what is the
problem with this code?
private void setBitmap() {
if (photoUri != null) {
try {
Bitmap theBmp =
MediaStore.Images.Media.getBitmap(getContentResolver(), photoUri);
int img_orient=0;
String[] projection =
{ MediaStore.Images.Media.ORIENTATION };
Cursor mImageCursor = managedQuery(photoUri, projection,
"", null, null);
if ( mImageCursor != null ) {
mImageCursor.moveToFirst();
img_orient =
mImageCursor.getInt(mImageCursor.getColumnIndex(MediaStore.Images.Media.ORIENTATION));
mImageCursor.close();
}
// check to determine whether the image is rotated
Toast.makeText(getApplicationContext(), "orient:
"+img_orient, Toast.LENGTH_LONG).show();
if(img_orient==90) {
Bitmap scaledBmp = Bitmap.createScaledBitmap(theBmp,
(dm.widthPixels-100), (dm.widthPixels-100), true);
Matrix mat = new Matrix();
mat.preRotate(img_orient);
try {
mBitmap = Bitmap.createBitmap(scaledBmp, 0, 0,
(dm.heightPixels-50), (dm.widthPixels-100), mat, true);
scaledBmp.recycle();
scaledBmp = null;
} catch(Exception e) {
}
} else {
try {
mBitmap = Bitmap.createScaledBitmap(theBmp,
(dm.widthPixels-100), (dm.heightPixels-50), true);
} catch(Exception e) {
}
}
mZoomView.setImage(mBitmap);
theBmp.recycle();
theBmp = null;
play_audio();
} catch(Exception e) {
}
}
}
