I'm having problems with trying to rotate an image before cropping it. I have tried calling setRotation
on the Image View I want to rotate and it rotates the imageView successfully. I realized this wasn't a solution because when I call CropImageIntentBuilder it passes in the original Image View without any rotation.
In the code below I have tried a different approach by saving the image to a File and passing that file to CropImageIntentBuilder but I am still having the same problem. Please let me know if there is any advice you can offer on this or if I'm approaching this the wrong way. Also if I need to post more of the code from the app please let me know.
public static Bitmap rotateBitmap (Bitmap source, float angle){
Matrix matrix = new Matrix();
matrix.postRotate(angle);
return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(),matrix,true);
}
private void executeCropImageIntent() {
//This is the cropIntent that is called using nexuss 10
try{
bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), Uri.parse(mSingleton.mCropFileTemp.toURI().toString()));
//mSelectedImage.setImageBitmap(rotateBitmap(bitmap, 90));
rotateBitmap(bitmap, 90);
try{
FileOutputStream fOut = new FileOutputStream(mSingleton.mCropFileTemp);
bitmap.compress(Bitmap.CompressFormat.PNG, 85, fOut);
fOut.flush();
fOut.close();}
catch (Exception e) {
e.printStackTrace();
Log.i(null, "Save file error!");
// Toast.makeText(this, getResources().getString(R.string.messageMissingGPS), Toast.LENGTH_LONG).show();
}
}
catch (IOException e) {
Log.d("JudgeMainFragment", "cannot take picture", e);
}
CropImageIntentBuilder intentBuilder = new CropImageIntentBuilder(0, 0, 0, 0, Uri.parse(mSingleton.mCropFileTemp.toURI().toString()));
// intentBuilder.setSourceImage(Uri.parse(mData.getImage()));
intentBuilder.setSourceImage(Uri.parse(mSingleton.mCropFileTemp.toURI().toString()));
startActivityForResult(intentBuilder.getIntent(this), IJudgeSingleton.REQUEST_CODE_CROP_IMAGE);
}

You are calling rotateBitmap(bitmap, 90);
. but not assigning the returned BitMap
to any variable. and then you are using the old bitmap which is not rotated. so change this line
rotateBitmap(bitmap, 90);
into this
bitmap = rotateBitmap(bitmap, 90);
