Thanks for your patience. I would like to update you that Gif v89a format is already supported by Aspose.Imaging. Can you please share some more details about tiff v6? If it is CCITT T6 then we already support it too. PNG support is planned in v2.1. However, we will update you as soon as it gets available.
Please feel free to contact us for any further assistance.
This is to inform you that we are preparing the release of Aspose.Imaging for Java 2.4.0. The aforesaid release fully supports Gif (v89a), Tiff (CCITT T6) & PNG (v2) formats. As soon as the new version is available for public use, we will notify you here with the download link to the upgraded API.
In the meanwhile, please feel free to write back in case you have any further questions or concerns.
