# CGImagePropertyOrientation.left

The encoded image data is rotated 90° clockwise from the image’s intended display orientation.

## Declaration

```swift
case left
```

## Discussion

Discussion The (x,y) pixel coordinates of the origin point (0,0) represent the bottom row and leftmost column, respectively. Pixel (x,y) positions increase bottom-to-top, left-to-right. If an image is encoded with this orientation, then displayed by software unaware of orientation metadata, the image appears to be rotated 90° clockwise. (That is, to present the image in its intended orientation, you must rotate 90° counter-clockwise.)
