Corel Painter was bought from MetaCreations and was better-known as Fractal Painter in the 'old days'. It has also supported network-painting for a long time. I don't know if they intend it to supercede PhotoPaint (that would be fine if it means a better chance of seeing a Linux version). Ahh, I didn't realize Corel had bought Painter ... so now the name "Network Painter" makes more sense! I agree that it would get messy - the stuff I saw on the screen was obviously the result of a bunch of clashing artists. I think the full power of the GIMP would be useful in many networked situations: I agree, although usefulness is a secondary consideration to me. I'll take fun over usefulness most days. Having both is just a bonus. =) Now now ... that's exactly the attitude that has got the GIMP the interface it has today. ... and I love it! :) If UI stuff was also transmitted then it would be a _great_ remote teaching tool. I don't know what the actual mechanism for Painter's network- painting is, but I understand that it works perfectly nicely over modem. Hence I assume that they try to avoid sending actual pixmap data as much as possible! As long as both images are sharing the same random number stream, two GIMPs should be able to duplicate each other's rendering exactly. So, in that diagram of all the components of GIMP 2.0, each edge should probably be considered a candidate for "networking".

FWIW, I was reading the release notes for gtk-xemacs last night. One missing feature of that port is multiple display capability, and the reason given is lack of support for it in Gtk/Gdk. sherm--

Basically there were a bunch of people all painting on the same image via the network. Something worth duplicating in the GIMP? This does sound like a fun thing to do, but I don't see it working all that well with the gimp. A large part of the gimp consists of filters and such. If many people were applying filters at the same time, hell would break loose on the poor image. If all that is wanted is drawing then a much simpler program would be better. Corel's PhotoPaint program is a full GIMP-like paint program and people seemed to be having a lot of fun with it. I agree that it would get messy - the stuff I saw on the screen was obviously the result of a bunch of clashing artists. I think the full power of the GIMP would be useful in many networked situations: As a collaborative work tool ... If only one person was working on each layer, there would be essentially no contention. With some workflow management it might be a good ink-paint-composite pipeline tool. If UI stuff was also transmitted then it would be a _great_ remote teaching tool. Imagine people popping into IRC with hard-to-explain problems and just granting access to their NetGIMP to someone who offers to help.

Basically there were a bunch of people all painting on the Something like emacs' opening multiple views on different DISPLAY's? Can gtk+ do that? One display server-specific thing that gets built into a particular compilation of GTK+-1.2.8 are choices about Xinput implementation, via the GTK--xinput configuration switch. Not sure how events sort out when one instance of GTK is faced with different flavors of Xservers with different tablet drivers that map their valuators into XEvents differently. I don't think that emacs has to deal with anything beyond core pointers and keyboards and is insulated from the XInput morass. What? You can't use multiple pressure-sensitive styluses in emacs? I'm surprised ... I thought emacs did everything. Tom? What was the mix of hardware? Or were all the platforms uniform? It was in the CAL and I think it was a cluster of Windows machines... or Macs ... or a mix. I didn't walk all the way around the cluster. Oops. I didn't look very closely at how it was working, but it appeared to me that it was actually a full copy of Network Painter per machine and they were "sharing" the image somehow. That is, I think painting and filters were calculated on the client side. Of course I have nothing with which to back up that supposition. People just seemed to have realtime feedback on their own machines. I have no idea how it handled locking/serialization. The users didn't need to know and were enjoying their group paint session. There was even a text chat window where they were discussing the image. In any case I think our question needs to be "how would it work best for the GIMP?". I think a "network tile source" would make sense. Another argument for abstracting the tile system from GEGL? *grin* Cheers, Tom -- -- Tom Rathborne [EMAIL PROTECTED] http://www.aceldama.com/~tomr/ -- "We promise according to our hopes, and perform according to our fears." -- -- Francois, Duc de la Rochefoucauld
