Use the following piece of code to set proper width and height for camera intent.

            Intent intent = new Intent( Intent.ACTION_PICK,
            MediaStore.Images.Media.INTERNAL_CONTENT_URI );
    intent.putExtra("outputX",
            width_of_output_image);
    intent.putExtra("outputY",
            height_of_output_image);
    intent.putExtra("aspectX", 1);
    intent.putExtra("aspectY", 1);
    intent.putExtra( "scale", true );
            startActivityForResult( intent, 1 );

I think this must help you:-

Bitmap.createScaledBitmap(Bitmap src, int dstWidth, int dstHeight, boolean filter);

回答4:

    BitmapFactory.Options optionsSignature = new BitmapFactory.Options();

    final Bitmap bitmapSignature = BitmapFactory.decodeFile(
            fileUriSignature.getPath(), optionsSignature);

    Bitmap resizedSignature = Bitmap.createScaledBitmap(
            bitmapSignature, 256, 128, true);

    signature.setImageBitmap(resizedSignature);
