(The ability to specify a operation as a graph, stored as XML for instance, right now such meta operations need to be written directly in C which is a bit cumbersome for rapid prototyping.) 2.

What about error checking? What operations are supported? I haven't tried this recently. I'm not sure what happens if there are errors in the input XML file. You may get either an incomplete GeglNode structure (ie. one not containing all parts of the input XML) or NULL. The API doc doesn't specify which. All GEGL operations can be used in an XML file. 2.

Re: [Gimp-developer] Extending GIMP Plugins
Hello all, Here is another way I thought I could give some form of extensibility to a plugin user. Say, that I want my plugin to be a single entry point to all the Image processing operations possible with GIMP. What I do is display all the GIMP functions to the Plugin user via the Plugin User Interface(GUI). Then the user selects the operation that is to be performed and the plugin sets off to do the necessary job. I am assuming here that the functions of the GIMP that I list for the user is only those for which there exists a API entry in the libGimp. In the background when the user selects a particular operation, the corresponding API function is called. This is of course an assumption to simplify the thought process. Am i thinking in a way that could possibly be implemented? or is the word extensible remotely applicable to my idea?

A quick search on the web returned this tutorial with screenshots of the old X11 version that I used: http://www.cse.psu.edu/~cg585/cantata-over.html Just imagine that the glyphs (the boxes that can be connected) could be the operations that GIMP offers through the PDB. It seems that Khoros Cantata has been acquired at least twice by different companies, has been ported to Windows, and is now sold as Accusoft VisiQuest: http://www.accusoft.com/products/visiquest/overview.asp The interface has changed a bit, but it is still based on the same ideas of connecting glyphs providing various functions. By the way, this brings back some memories about what I did in 1993 as an exercise for a course in digital imaging. Students were asked to write a new filter for Khoros and use it to perform some interesting image transformations. I decided to write a filter that would use various correlation methods to reconstruct an image in which the lines were shifted horizontally by some random amount. The default method was optimized for un-shifting images at TV resolution (PAL) that were shifted by one of three predefined offsets picked at random. The method worked surprisingly well. The code and the results were presented to the professor. He asked if, by any chance, this could be used to decode Canal+ images (a pay TV channel that was popular in several European countries). And the answer was yes. Not in real time because the 486 processors that were common at that time were not fast enough, but the method worked well with recorded TV streams (sometimes even without using inter- frame correlations). Ah, I still have fun when I remember this and when I consider that the professor gave one of the top marks for this exercise. -Raphaël ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Re: [Gimp-developer] Extending GIMP Plugins
Von: Amit Kumar Saha [EMAIL PROTECTED] Is there any way to make GIMP plugins themselves extensible. My point here is that, can we make a GIMP plugin which allows itself modifiable by a end-user to include a new functionality without much of a hassle on part of the end-user. The trick here isn't creating an extensible plugin. The trick is defining what without much hassle on the part of the end-user really means. Who's the end user? Joe Artist or Edward Engineer? Sven's granny or a bunch of kernel developers? In general, making a piece of software extensible requires two main components: a grammer understandable by the core software and an API accessible through that grammer to core functionality. One problem you'll have to address is what parts of the API are visible to the plugins and what parts are not. To make a piece of software extendable you could ignore the API portion and create a simple grammer that end users could use to essentially configure the plugin. Imagine a simplistic scripting language that simply sets a bunch of variables that the main plugin normally requires you to set manually using a series of dialogs or tabs. Wouldn't even require anything as complex as Perl or Python - it could just be a series of name/value pairs. But this isn't really extension, its configuration. More complex examples would include exactly what GIMP already does with it's language extensions. You can load a dll easily enough or embed an interpreter like Perl or Python. But is programming in Perl or Python easy to your end user? A more common approach these days is to allow extension via XML. You can easily embed an XML parser into a plugin (I've used libXML2 in my plugins to save configuration data). But then you have to decide if writing XML by hand is easy for your users. Not to mention defining the XML Schema or DTD for the language. In the end, though, what you've done is create a new programming language. If you're doing that, and started with the intention of making it easy to use, you might as well use a well known language like Perl or Python instead. You could provide a series of core features in the plugin that could be used in a reorderable stack and then build a GUI that used drag and drop to rearrange that stack. Sort of like arranging a series of existing plugins to be run in any given order. The plugin would then process in the order defined by the stack. The problem here is that you're simply providing a mechanism for using existing features, not allowing the user to extend that feature set. So before you decide on the mechanism, you have to define who will use it and what you're really trying to allow them to do. Does any one know of a method to do this or any GIMP plugin which already does this? I'm not aware of any plugins that provide this though it wouldn't suprise me if someone had already done something similar. Plugin interfaces are a standard part of many applications these days but I think you'd be hard pressed to find any that don't require some level of programming expertise to use. -- Michael J.
