From the release of Aspose.Imaging for Java 2.1.0, all Aspose.Metafile for Java packages have been merged and moved into Aspose.Imaging for Java. Migrating from legacy Aspose.Metafiles code to Aspose.Imaging 2.1.x or higher only requires a few changes in the existing code. This article provides a list of those changes and a class mapping for an overview of the changes.
Notable Changes for Existing Users
Since Aspose.Imaging has taken over the Aspose.Metafiles API, we have tried to keep everything as it was in Aspose.Metafiles API. However, a few changes were necessary. When migrating from Aspose.Metafiles to Aspose.Imaging, the following should be taken into account:
- The MetafileImage class no longer contains the write method, instead use the standard Aspose.Imaging approach using save method which provides the same functionality.
- The MetafileImage class no longer contains the static LoadMetafile method, instead use the standard factory method, Load, which provides the same functionality.
- The EmfMetafile and WmfMetafile classes have been renamed EmfMetafileImage and WmfMetafileImage respectively.
