GDI+ for format images (png, jpg, etc.) supports two
types of sources: files and IStream interface.
I am afraid there isn't flat DLL functions that would
allow to write data to IStream (as there were to read).

Though it would be possible to easily implement IStream
calls with the "pcall" addon, it seems not nice to provide
such dependency on a proof of concept example.

This is another reason and use case to include 
Pointer Call/Interface Call support in cd DLL
interface.

For an example of how easy it is to call native
COM interfaces like IStream (not IDispatch like wd 'ole...') see
    http://www.jsoftware.com/jwiki/Guides/Windows_Progress_Dialog
a small class to implement standard Windows async progress dialog.

In fact, in J it is even cleaner and nicer than in C or C++.
