CAMERA_I2CSize*

Syntax

#include <twl/camera.h>

CAMERAResult CAMERA_I2CSize(CAMERASelect camera, CAMERASize size);
CAMERAResult CAMERA_I2CSizeAsync(CAMERASelect camera, CAMERASize size, CAMERACallback callback, void *arg);
CAMERAResult CAMERA_I2CSizeEx(CAMERASelect camera, CAMERAContext context, CAMERASize size);
CAMERAResult CAMERA_I2CSizeExAsync(CAMERASelect camera, CAMERAContext context, CAMERASize size, CAMERACallback callback, void *arg);

Arguments

camera Camera to configure (CAMERA_SELECT_IN, CAMERA_SELECT_OUT, or CAMERA_SELECT_BOTH).
context Context to change.
size Camera resolution.
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 camera resolution.

The CAMERA_I2CSizeEx function is used to change the setting with a specified context. The non-Ex functions change the setting for both context A and B. See CAMERAContext for information on contexts.

Unlike CAMERA_I2CSize, the CAMERA_I2CSizeAsync function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.

Do not set CAMERA_SIZE_VGA in this function while either CAMERA_FRAME_RATE_30_TO_5 or CAMERA_FRAME_RATE_30 is specified in the CAMERA_I2CFrame* functions. You can no longer receive capture data if these two settings are made at the same time.
