Hello,

I got this idea while studying and I wonder if its possible / hard / done already and I didn't spot it:

Plugin-Mixer:

A window that allows you to select a few plugins, put them in order you want them to be applied, modify their parameters and apply them on the current image. The window should allow the user to save the "combination" and reuse it for other combinations.

GUI idea description: + You select plugin by name from an auto-complete text box. + You can rearrange the plugins with drag-n-drop + By double clicking on a plugin it shows up the plugin parameters configuration window (if any).
+ By clicking "preview" it shows a small preview of the current image after applying the plugins
+ By clicking "apply" it applies the plugins one by one on the current image

Advantages it offers: + Users can create and reuse easily their "combinations" of plugins that they use often. This increases productivity. + When you normally apply few plugins over a picture, there is no easy way to modify the parameters of the first plugins you applied (undo works from the end). This would allow more control over using plugins. + Could potentially generate plugins (generate their code) [not so sure about this though..]

Your comments / ideas will be appreciated :) Thanks!

(My other proposal: http://socghop.appspot.com/gsoc/student_proposal/private/google/gsoc2010/avgoustinos/t127081249399)

That's exactly what I was thinking but I didn't know about GEGL!

I could work on this for GSoC. Making it possible to import/export meta-ops from XML and improve the existing graph editor so a user can define his own meta-ops :)

Please consider this as an alternative proposal, if the "User Friendly Plug-in Browser" doesn't sound feasible (at the moment) or not desirable.

Thanks!!

This is related to what in GEGL is known as meta-ops, processing operations that are implemented in the terms of other GEGL operations. For instance the dropshadow operation is a combination of the operations gegl:over, gegl:translate, gegl:opacity, gegl:gaussian-blur, gegl:src-in and gegl:color. (unsharp mask is another example of such a composite meta op). At the moment these operations are written in .C, but it would be possible to define them as XML or some other serialization format. Editing such operations could also be done in a visual way using nodes connected with hoses or other metaphors.

There is a bug in GEGL about loading such operations from non C files: https://bugzilla.gnome.org/show_bug.cgi?id=465743

I applied with one proposal and discussed it on the mailing list (https://lists.xcf.berkeley.edu/lists/gimp-developer/2010-April/024552.html). The issue with that proposal is that there is no easy way to retrieve the default values of the plugins. It might be possible in the future (by changing PDB). I could implement the idea without having a "sure" way of getting the default values or I could work on another project (second project proposed through email).

I understand if its impossible to change idea now and I would appreciate it if you could do that.

Thanks, Avgoustinos

You mean you managed to apply before submissions were closed a week ago?
