I just finished my camera activity and it's wonderfully saving the data. What I do after the picture is taken:
protected void savePictureData() {
try {
FileOutputStream fs = new FileOutputStream(this.photo);
fs.write(this.lastCamData);
fs.close(); //okay, wonderful! file is just written to the sdcard
//---------------------
//---------------------
//TODO in here: dont save just the file but ROTATE the image and then save it!
//---------------------
//---------------------
Intent data = new Intent(); //just a simple intent returning some data...
data.putExtra("picture_name", this.fname);
data.putExtra("byte_data", this.lastCamData);
this.setResult(SAVED_TOOK_PICTURE, data);
this.finish();
} catch (IOException e) {
e.printStackTrace();
this.IOError();
}
}
What I want to is already as comment given in the code above. I dont want the image just to be saved to file but to be rotated and then saved! Thanks!
//EDIT: What I am currently up to (Works but still runs into memory issues with large images)
byte[] pictureBytes;
Bitmap thePicture = BitmapFactory.decodeByteArray(this.lastCamData, 0, this.lastCamData.length);
Matrix m = new Matrix();
m.postRotate(90);
thePicture = Bitmap.createBitmap(thePicture, 0, 0, thePicture.getWidth(), thePicture.getHeight(), m, true);
ByteArrayOutputStream bos = new ByteArrayOutputStream();
thePicture.compress(CompressFormat.JPEG, 100, bos);
pictureBytes = bos.toByteArray();
FileOutputStream fs = new FileOutputStream(this.photo);
fs.write(pictureBytes);
fs.close();
Intent data = new Intent();
data.putExtra("picture_name", this.fname);
data.putExtra("byte_data", pictureBytes);
this.setResult(SAVED_TOOK_PICTURE, data);
this.finish();
Before you create your FileOutputStream
you can create a new Bitmap
from the original that has been transformed using a Matrix
. To do that you would use this method:
createBitmap(Bitmap source, int x, int y, int width, int height, Matrix m, boolean filter)
Where the m
defines a matrix that will transpose your original bitmap.
For an example on how to do this look at this question: Android: How to rotate a bitmap on a center point
