I had looked at GEGL, but it is like a low level api for image manipulation, if I unterstood well, for a simple task (like, add a mask), you have to do a long sequence of operations. With GEGL you have to talk with it using a DAG, in wicth images are edges, and operations are nodes, its sound like a very complex task (and you have to know about image proccessing). If it is the way, I will use it and I will add a layer to make things a litle bit more easy to the user of this 'extension'. It is just, I think I have to know a lot about digital image proccessing to make a correct use of GEGL. I believe that if gimp will use it, and I can develop a thing that can 'talk' with GIMP, that will be perfect. Again, I know a little about those topics, if it is the recomended way to use GEGL or if I misunderstood about GECL function, I will use it instead GIMP. Please, if you can clarify the subject to me, that will be nice. Thanks again. I'm afraid I can't help you more, as I'm not a gimp/GEGL developper: I don't know where GEGL will stop, and where Gimp will start. Only Sven and Pippin can answer...

Does GEGL work like Mariano thought libgimp work?

Re: [Gimp-developer] libGimp
Sven: Really, thanks for your repply. Yes, I misunderstood. Then suppose that I develop that plug-in, something that allow an interproccess comunication with the GIMP, i still will have to install the GIMP, to start it in some way, and then to use it. I wonder if it is a good solution to use interproccess comunication instead of link or add it to a project (may be I cant still see the dimension of the task). Is it more difficult? or is there nothing developed that will make more easy the task? or is it impossible for some reason? or the plug in way can be a good starting point?
Another possibility can be: add to the gimp-console, this plug-in ability, or develop something like the gimp-console with this functionality, and allow it to be compiled like a library. But, if the way is a plug-in, it must have two parts: one (that must be installed in GIMP) that is responsible to expose the GIMP functionality, information about the environment (the plug-ins installed, the GIMP version,..). And a client part, that encapsulate the interproccess comunication. Because the GIMP runs on a big amount of systems, do you recommend something about the kind of ic that is the best to use? GIOChannel? signals? socket? pipe? another? In some point, the idea is, form a console test program, and like the first possible step:
#include gimp_remoteclient.hint main (void){ Gimp_Remote_Start ( ); Gimp_Image aGImg = Gimp_Remote_OpenImage ( aImg.png ); /*in a future, add image manipulation, filters and layer access,...*/
Gimp_Remote_SaveImageAs ( aGImg, AImg2.png, Gimp_ImageFormat::PNG ); Gimp_Remote_End ( ); return 0;} I am sorry about my little knowledge about this idea and how to implement it -I really want to extend GIMP in this direction, I think it will be very nice.

[Gimp-developer] libGimp
Hi. I am new in this list. I had subscribed because i want to use the gimp in a way I had found little documentation (maybe i had looked for it in a wrong way ). Gimp is a very nice development, and a great tool, I know its possible to use it like a user (thought its user interface), add it plug-ins (in scheme or python), and use it in a batch mode. But I want to extend it to allow to use its api from another program (suppose i had a console program and I need to edit a photograph, it would be nice to have access to a libgimp utility -and all its dependencies files- with the minimum install process). Why? I am trying to develop a mozilla component to add this feature. I hope the short description above its enough clear to ask you: any tips or suggestions for this task? I think its a big and complex task but I want to try. Thanks in advance.

[Gimp-developer] Libgimp newbie development path
Hi, s s said: I'm hoping to develop an application that leverages the Gimp's functionality, but uses its own GUI and some other libraries. My ideal situation would be this: - The user opens my application and the only reference to the Gimp that can be directly seen by them are Gimp licensing requirements, while my application would be using the Gimp behind the scenes for basic image manipulation handling. You might want to look at Seashore, a Mac application which uses some of the GIMP internals (notably the file format image structure). That might give you some ideas. My current idea is to develop a plugin for the Gimp which uses my GUI(not using GTK). I'm basing this off of the Gimp pluggin development samples and tutorials available. However, is this the correct path I should be taking? Will I be able to start the pluggin from my app without having the user manually open it from the Gimp? No - plug-ins are standalone apps that communicate with an already running GIMP. Finally, is there a better way to use libgimp so that I can just use Gimp functionality from my application without having to startup the full Gimp application and use a pluggin? Afraid not - short of cutting pasting code (which is possible). Lots of libgimp has no GTK+ dependency - adding a different GUI should be doable, but hard.
