Please do not use com.sun.image.codec.jpeg.JPEGCodec

Aspose.Cells Product Family

I have noticed that from version 7.6.x onwards that the cells library for java is using this class. Please remove dependencies on the sun packages. This is preventing me from upgrading to the later versions of cells.

You are not recommended to use the sun packages as they are not supported apis. This will be problematic if they decide to remove these classes at some point. For more details see:


FAQ - Sun Packages

There are ways to code without the dependencies on sun packages, which I hope your developers are aware of. I couldn’t find your issue tracking system which is why I have posted here. Please add this to your system.

Cheers,
Agnes

To be more specific we use your Aspose libraries in an OSGi context, and com.sun.* classes are not available there. Also, this class is removed in java 7

Hi,

We have evaluated your requirements in details. We know we can use ImageIO to read/write JPEG images instead of com.sun.image... and that is just what we did with JPEG image data in the versions prior to 7.6. However, for some users' requirements regarding the quality of the output jpeg images, we have to use some advanced properties for the jpeg images, such as, PEGEncodeParam.XDensity/YDensity, ...etc. For those properties, we cannot find the corresponding settings that can be used by ImageIO APIs. Anyways, we will still try to make the invocation of com.sun.image to be used as an optional step, for those environments that APIs of com.sun.image... are unavailable, we will create JPEG image with default quality.

Thank you.
