I'm sure it could, but presumably there's a reason you want to do this?  It might help if you also explain what you want to achieve as you may not actually need to perform the conversion...

Hi blindfish and ALL,

     You are right. In fact, what I need is to write the content of a PImage / PGraphics object with a graphics format (e.g. GIF, PNG) into a Java outputstream. The "save()" and "saveFrame()" methods seem not providing this function. I think that if PImage / PGraphics could be converted into Java Image / Graphics, I may then pipe the graphics data into a Java outputstream for my purpose.

     Is there a way for achieving this ? Thanks.

Regards

Lawrence

 

Look at the http://forum.processing.org/topic/saving-a-file-to-the-web-my-server thread. To save to a Web server, an image must be converted to a stream, you should be able to reuse code there.

Hi phi.lho and ALL,

     It seems that the addon library "postToWeb" is just doing what I need.

     Thanks for your suggestion.
