54<H2>Description</H2>
55<P>
56Changes the camera resolution.<BR><BR> The <code>CAMERA_I2CSizeEx</code> 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 <A href="CAMERAContext.html"><CODE>CAMERAContext</CODE></A> for information on contexts.<BR><BR> Unlike <code>CAMERA_I2CSize</code>, the <code>CAMERA_I2CSizeAsync</code> function returns control immediately and runs asynchronously. Use <SPAN class="argument">callback</SPAN> to confirm that processing has completed.<BR><BR>Do not set <CODE>CAMERA_SIZE_VGA</CODE> in this function while either <CODE>CAMERA_FRAME_RATE_30_TO_5</CODE> or <CODE>CAMERA_FRAME_RATE_30</CODE> is specified in the <A href="CAMERA_I2CFrameRate.html"><CODE>CAMERA_I2CFrame*</CODE></A> functions. You can no longer receive capture data if these two settings are made at the same time.
