AnnRotate example for C++ 5.0 and later
Note: This topic is for Document/Medical only.
For more information on declaration and unlocking procedures used in testing this example, refer to Annotation Declaration Information.
//This example uses the AnnFlip, AnnReverse, and AnnRotate methods. To code this example, add a command button with and ID of IDC_TEST to the example you created in Loading and Displaying an Image. For best results when you run the example, draw two objects in opposite corners, and use the right mouse button to select all annotation objects. The command button then lets you cycle through the AnnFlip, AnnReverse, and AnnRotate methods.
