Vertical inversion refers to an image or object being flipped vertically, resulting in it being upside down.
In simpler terms, if you imagine a line running horizontally through the center of an image, vertical inversion means that the top half of the image is swapped with the bottom half. This is different from horizontal inversion (also called mirroring or reflection), where the image is flipped left-to-right.
Think of it like this:
- Original Image: A person standing upright.
- Vertically Inverted Image: The same person standing on their head.
- Horizontally Inverted Image: The same person's mirror reflection.
Key Characteristics of Vertical Inversion:
- Upside-Down Orientation: The primary characteristic is the subject appearing upside down.
- Top and Bottom Swap: The content initially at the top of the image now appears at the bottom, and vice-versa.
- Preservation of Horizontal Relationships: The left-to-right relationships within the image remain unchanged.
Examples of Vertical Inversion:
- Photography: Flipping a photograph vertically can create an artistic effect or correct an improperly oriented image.
- Screen Display: Sometimes, screens can inadvertently display content vertically inverted, requiring a setting adjustment to correct.
- Image Editing: Image editing software provides tools to easily perform vertical inversions.
