# CAMERA_I2CFlip*

## Syntax

  `#include <twl/camera.h>`
  `CAMERAResult CAMERA_I2CFlip(CAMERASelect camera, CAMERAFlip flip);`
  `CAMERAResult CAMERA_I2CFlipAsync(CAMERASelect camera, CAMERAFlip flip, CAMERACallback callback, void *arg);`
  `CAMERAResult CAMERA_I2CFlipEx(CAMERASelect camera, CAMERAContext context, CAMERAFlip flip);`
  `CAMERAResult CAMERA_I2CFlipExAsync(CAMERASelect camera, CAMERAContext context, CAMERAFlip flip, CAMERACallback callback, void *arg);`

## Arguments

camera | Camera to configure (`CAMERA_SELECT_IN`, `CAMERA_SELECT_OUT`, or `CAMERA_SELECT_BOTH`).
context | Context to change.
flip | Flipping to configure.
callback | Function that is called when asynchronous processing has completed.
arg | Arguments when the callback function is invoked.

## Return Values

Returns `CAMERA_RESULT_SUCCESS` if configuration was successful.

## Description

Changes the flipping setting for the camera.
The `CAMERA_I2CFlipEx` function is used to change the setting for a specified context. The non-Ex functions change the setting for both context A and B. See `CAMERAContext` for information on contexts.
Unlike `CAMERA_I2CFlip`, the `CAMERA_I2CFlipAsync` function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.
Note:
If camera settings are changed using any of the `CAMERA_I2C*` functions, the changes may be delayed for approximately one frame before they are applied. Consequently, note that if camera settings are changed while capturing, the application may not be able to get an updated image (an image with changes applied) at the time the application intended.
