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. See more at http://www.jsoftware.com/jwiki/Addons/general/pcall 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++. ____________________________________________________________________________________ Need a quick answer?
