Hi Xiong,


Thank you for contacting Aspose support.

We have evaluated your presented scenario while using the latest version of Aspose.Cells for Java 8.3.0.3, and we have noticed that setting the anti-aliasing isn’t taking effect while converting sparkline to image. We have logged this incident in our bug tracking system under the ticket CELLSJAVA-41118 for further investigation & correction purposes. Please spare us little time to properly analyze the scenario, and to provide the fix at earliest possible. In the meanwhile, we will keep you posted with updates in this regard.
