How do I get PNG image data as a decoded bytearray?

[Xavier]

I would like to read a PNG image and have the data accessible to me as
a decoded bytearray. How would I go about doing this? Any help is
appreciated.

Use the Apache Sanlasan project if you cant load the PNG using java's
built in IOImage.

By read do you mean upload it from a location on the client side?

For that you need to use a GWT FormPanel and Apche commons ServletFileUpload to get the file item then do the usual java io process to convert to a byte array.

If this is not what you looking for , please elaborate on the question.

Yes I need the bytearray on the clientside. Can I use an
imageresource for this?
