Provides a callback method for the `EnumerateMetafile` method.

**Parameters:**
| Parameter | Type | Description |
| --- | --- | --- |
| recordType | int | Member of the [EmfPlusRecordType](../../com.aspose.drawing.imaging/emfplusrecordtype) enumeration that specifies the type of metafile record. |
| flags | int | Set of flags that specify attributes of the record. |
| dataSize | int | Number of bytes in the record data. |
| data | com.aspose.ms.System.IntPtr | Pointer to a buffer that contains the record data. |
| callbackData | [PlayRecordCallback](../../com.aspose.drawing.imaging/playrecordcallback) | The argument is not used. |

**Returns:**
boolean - Return true if you want to continue enumerating records; otherwise, false.
