Image rotation parameters

Parameter name Abbreviated command Types Value range Command description Default value Required or not
angle a int -360～360 Specify the image rotation mode.
A positive value indicates clockwise rotation, e.g., a_60;
a negative value indicates counterclockwise rotation, e.g., a_-30.		 0 No
orientation o int 0,1,2 Automatically rotate based on exif information.
o_0: Follow the original image’s default orientation without automatic rotation;
o_1: Rotate first, then thumbnail;
o_2: Thumbnail first, then rotate.

Example
