Method Detail

invoke

public abstract boolean invoke(com.aspose.ms.System.IntPtr callbackdata)

Provides a callback method for deciding when the DrawImage method should prematurely cancel execution and stop drawing an image.

Parameters:

callbackdata - 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:

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.
