DrawImageAbort()
public DrawImageAbort()
invoke(System.IntPtr callbackdata)
public abstract boolean invoke(System.IntPtr callbackdata)
Provides a callback method for deciding when the DrawImage method should prematurely cancel execution and stop drawing an image.
Parameters:
| Parameter | Type | Description |

| callbackdata | com.aspose.ms.System.IntPtr | Internal pointer that specifies data for the callback method. This parameter is not passed by all DrawImage overloads. You can test for its absence by checking for the value System.IntPtr.Zero. |
Returns:
boolean - This method returns true if it decides that the DrawImage method should prematurely stop execution. Otherwise it returns false to indicate that the DrawImage method should continue execution.
