+Flips the image horizontally, vertically, or both. Can be used with the `rotate` parameter to set the orientation of an image.
+
+Flipping is performed before rotation. For example, if you apply `flip=h,rotate=90,` then the image will be flipped horizontally, then rotated by 90 degrees.
+
+Available options are:
+
+- `h`: Flips the image horizontally.
+- `v`: Flips the image vertically.
+- `hv`: Flips the image vertically and horizontally.
