1. Plug In Distribution and Gallery Maker
18 May 2001 - 19 May 2001 (29 posts) Archive Link: "Gallery maker ..."
People: Garry R. Osgood, Raphael Quinet, Branko Collin, , Sven Neumann
Fabian Frederick posted that he had created a gallery make plug-in that did batch conversions (located at http://www.dtlord.com/gallery.) Fabian then inquired how to get this included in the distribution. Raphael Quinet said that posting a message to the developers list was the best way. Since it was a perl script, Marc would be the one to review it for distribution. Raphael also suggested including some examples of the output on the web page. Stefan Stiasny had several suggestions about cleaning up the code, covering some error handling and Gimp interface issues. Fabian posted again saying GalleryMaker had been fully reviewed and modified. Fabian also asked if it was mandatory it register the plug-in in order to reach the Gimp core application. Sven Neumann said registering a plug-in was a very good idea since it allows people to find it. Sven also added that plug-ins SHOULD be distributed outside the core package, but now suitable system had yet been devised. The goal was to have the new system ready for the 1.3.0 developers release. Dave Neary thought that plug-ins were not necessary to the Gimp, so they should be distributed separately. A plug-in package would solve this problem. Additionally, plug-ins should be in a different CVS module from the core. Garry R. Osgood said " PLUGIN_MAINTAINERS was introduced into the distribution on Tuesday, January 04, 2000; in the five hundred and two days since that date, of the 162 core plugins cited in that file, 52 have maintainers. By this metric, only thirty-two percent of the core plug-ins are supported. " Gary thought the question of maintenance and distribution were closely related.
Branko Collin asked when changing a few line of code
made something a new plug-in and
when the original author should be sent a patch.
Raphael suggested that if useful features can be added without breaking
the API, then a patch was in order. Raphael had four suggestions about
2. Print Plug-in
19 May 2001 - 20 May 2001 (3 posts) Archive Link: "Print plugin"
People: , Robert L Krawitz, Sven Neumann
Robert L Krawitz announced the alpha release of the print plug-in with Gimp Print 4.2. Robert asked what needed to be done about syncing up with the next Gimp release. Sven Neumann said it could be included if it was sufficiently tests and suggested the plug-in and the enxt version of the Gimp be released before the print plug-in was officially included.
3. Plug-In Distribution
20 May 2001 - 21 May 2001 (11 posts) Archive Link: "plug-in distribution choices"
People: Branko Collin, Guillermo S. Romero, Sven Neumann, Sven Neumann , , Garry R. Osgood
Branko Collin wanted to discuss plug-in distribution, after it had
been mentioned earlier in Issue #44, Section #1
(18 May 2001: Plug In Distribution and Gallery Maker)
. First, Branko offered a definition of the
what are considered plug-ins? Everything that goes into the directory 'plug-ins'?
Branko felt that part of the problem
centered around deciding which scripts belong in the core
distribution and which don't. Branko suggested the following
classes of scripts be included in the core distribution:
Sven Neumann agreed with Branko that it was time to have this discussion again. Sven stated " Our goal is to have as much functionality as possible in plug-ins. This reduces the size of the core, makes it cleaner and improves maintainability of the core. This makes this rule questionable especially since "a task that the Gimp should provide" is much too vague." Sven disagreed that another package having some functionality was reason enough to distribute particular plug-ins with the Gimp. Sven took a different approach and discussed what a plug-in should look like and why they were there.
A very important point for distributing a plug-in is to have a maintainer that feels responsible for it. The core Gimp maintainers would like to only have a set of basic image manipulation tasks in the core package and they would feel responsible for keeping them up to date, handling bug-reports and discussing patches. Such basic plug-ins would include for example Blur, Gauss-Blur, Sharpen, Rotate, and a set of important file-plug-ins to give only a few examples. Other plug-ins could be grouped into smaller packages for special purposes. For example there could be a gimp-web-plug-ins package that adds functionality like GIF-Save, Anim-Optimize, ImageMap and others. Such a package would have a maintainer who is responsible to handle bug-reports and keeping the package in sync with the core. Installing gimp would then be a process of installing gimp-core and a set of plug-in packages that fit the needs of the user. Such an approach has some obvious advantages but also a bunch of drawbacks:
The packages would have interdependencies. The web-plug-ins package might include a gimp-perl script so it would require gimp-perl. Of course everything in the web-plug-ins package but this script would work w/o gimp-perl so actually gimp-perl is not required but only recommened. I can however only think of one binary package system that can handle those kind of weak interdependencies (debian). The packages should not overlap and they should share the menus intelligently. This would require some interaction between package maintainers. I think however that this should be doable. On multi-user systems the administrator who installs gimp can not decide what packages the users might want. One solution is to install them all. This would however lead to overcrowded menus. A problem that could be solved by a plug-in manager that knows about all plug-ins that are available and lets the user choose what plug-ins she wants to see in the menus. Having gimp split up into dozens of packages will make installation difficult. Again a plug-in manager that knows about all available plug-ins out there, collects and installs them would help. It turns out we need a plug-in manager. What functionality should such a beast have? Here's a list of things that came to my mind: It should read a number of plug-in lists: a list of all available plug-ins that is distributed with the core gimp and can be updated through the web. A list of plug-ins that are installed locally do not necessarily appear in the menus. It should have meta-packages of plug-ins similar to the task-lists Debian has so a user can install a bunch of plug-ins with a single click. One meta-package would be "All plug-ins", other tasks could be "Web Publishing", "Photo Retouching", ... It should be able to download and install precompiled binary packages or download sources, compile and install them. A solution for the binary packages would be to use the binary packaging system provided by the distribution. Since there are a bunch of different distrbutions out there, this might be tricky. That should be enough food for thought for now. Please comment.
Guillermo said he would make a basic plug-in handler so users can remove and add them to menus, if installed, and let the real development focus on getting and installing the plug-ins. Guillermo suggested using a package system, which would mean a security audit for all UID 0 Sven agreed that dealing with binary packages would be cumbersome and that a solution would be to distribute source packages with a file (possible XML as described by Ingo) that describes the package to the next generation plug-in registry. Sven also added " For the moment we want to keep all plug-ins in the core package until we have ported Gimp to Glib/GTK+-2.0. This is because we think that a lot plug-ins will be ported very easily and having them all in one place might ease this task. Once the port is done (and we are going to start it very soon now), we should think about moving most of the plug-ins out of the core CVS module. Hopefully we have made up our mind on the new plug-in system until then. " Garry R. Osgood also agreed the Gimp developers did not have the resources to create binary plug-in distributions. Garry felt the general approach to plug-ins was useful, and mentioned that this could become a lot like a protocol. Branko added the issues sounded more like it centered around finding maintainers and offered the Debian tool as a means for packaging plug-ins. Sven pointed out that Debian tool was good for Debian users, RPMS were good for Red Hat users, and Binary was good for Windows Users.
4. Gamma Correction
21 May 2001 (3 posts) Archive Link: "GIMP and Gamma Correction?"
People: , Michael Natterer, Sven Neumann
Shlomi Fish asked where the Gamma Correction plug-in for the Gimp 1.2.x lived. Sven Neumann pointed to Image->Colors->Levels, saying the middle entry of the "Input Values" corresponds to Gamma. Michael Natterer added the display filter subsystem was disabled for 1.2.x because it was not finished and should be re-enabled in the HEAD to avoid bit-rot.
5. Plug-Ins, Menus and User Interface
21 May 2001 - 28 May 2001 (15 posts) Archive Link: "Plug-ins, menus and user interface"
People: Raphael Quinet, Sven Neumann, Branko Collin, Nick Lamb, , Simon Budig, Tuomas Kuosmanen
In relation to the discussion of plug-ins, Raphael Quinet
mentioned the menus were too crowded and new users could easily
get lost. To Raphael, distributing fewer plug-ins with the core
distribution did not solve this problem. Raphael suggested
different levels of detail, in a manner similar to GNOME.
Branko Collin added that this sounded like the new menus in Windows, where the most important and most used items are displayed. Shlomi said the computers at the faculty PC-Farm were always reset to the initial values, making the system annoying. Sven posted that 'man gimp' was your friend, since the --gimprc option allowed an alternate path to the RC file. Raphael clarified that all plug-ins must still be available, if only through the PDB and not the menus. Additionally, Raphael did not think the keyboard shortcuts should be changed, and that the bloat that came with customizing the Gimp until it was unrecognizable (a la mozilla and XUL) would slight coolness factor, but no usefulness. Lastly, Raphael pointed out that changing menu layout would affect the tutorials. Tuomas Kuosmanen disagreed that the new Windows menus were useful, because the forced the user to reread the menu every time it was displayed. Simon Budig agreed that the new Windows style menus were distracting, but sorting a menu item by importance was attractive. Branko Collin suggested a "tutorial theme" or having tutorials switch the user into advanced mode. Oliver thought that the dynamic menus allowed the user to always end up in the wrong type of menu, making the entire application look bad.
On a side note, Shlomi Fish thought the aim of the Gimp 1.3.x was to be independent of the GUI library. Shlomi added that this would make porting to windows easier since it could use Win32 controls. Sven said the plan was not to be totally independent from the GUI toolkit. "It's the Gimp Toolkit after all... " Sven said the current focus was to move the GUI interface from the core.
6. ANNOUNCE: Gimp-Print 4.0.5
26 May 2001 (1 post) Archive Link: "ANNOUNCE: Gimp-Print 4.0.5"
People: Robert L. Krawitz, , Robert L Krawitz
Robert L Krawitz posted the following announcement about Gimp Print:
This is a rerelease of Gimp-Print 4.0.5, which had some errors when released earlier this week. Thanks to Mike Sweet for managing this release. This is expected to be the last release in the Gimp-Print 4.0 stable line.
Gimp-Print 4.0.5 contains the following fixes and improvements over Gimp-Print 4.0.4:
7. Copyrights and Licenses
29 May 2001 (7 posts) Archive Link: "Copyrights and licenses"
People: Sven Neumann , Branko Collin, , Simon Budig, Sven Neumann, Guillermo S. Romero
Branko Collin asked which parts of the Gimp required their own licenses. Are all of the plug-ins covered because the Gimp is GPLed, which covers components. Sven Neumann said " Everything distributed with The GIMP should be GPL, LGPL or a compatible license. I know there are a few scripts/plug-ins that don't specify the copyright/license explicitely. If you want to go thru the hassle of fixing them, try to get in contact with the respective authors and ask if putting a GPL header is fine. Actually we assume that all plug-ins in the GIMP distribution are GPLed. " Dave Neary thought that things that depended on the Gimp, but were not in the core, could be under any old license. This allows companys to release propriatary plug-ins and modules (something Dave couldn't see any use for). Sven added that libgimp was LGPL s other people could use different licenses, but this didn't mean that any non GLP scripts or modules would be distributed with the Gimp. Simon Budig confirmed that the LGPL allowed propriatary links against the LGPLed libraries. Guillermo S. Romero thought a propriatary Pantone module or plug-in would be both useful and salable.
