Hi,
I'm using Camera.PreviewCallback.onPictureTaken to get an image byte
array, and try to do greyscale with this byte array. But it's not
working. It generates a broken image file in the sdcard.
Here is my code:
public void onPictureTaken(byte[] data, Camera camera){
byte[] newData=greyScale(data);
new SavePhotoTask().execute(newData);
camera.startPreview();
}
greyScale() is the function that doing grey-scaling, and
SavePhotoTask() is used to stored the byte array into sdcard.
I'm assuming that the array is correctly formatted since the data just
comes right from the camera, so what could the problem be?
