Re: [Gimp-developer] Another idea for GSoC: Plugin mixer
Hi, On Fri, Apr 16, 2010 at 10:34 PM, Avgoustinos Kadis avgousti...@gmail.com wrote: 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. Why does it have to be limited to plug-ins ? From user POV, there are actions she can make: adjust image levels, blur, etc. Some actions live in core, some in plug-ins, but why should user care where the action is technically implemented ? In some applications often used actions can be combined in the following way: user clicks 'Record', performs adjustments, experiments, undo, experiments again. When she is happy with the result she clicks 'Stop', and has the sequence of operations saved. Note: in order to construct sequence of actions she didn't have to perform any special actions, like drag-dropping plug-ins to a list, but instead work as she usually does (most intuitive way possible). Afterwards she can 'Play' the sequence on any image, on directory of image files, etc. IMO, in order to make serious improvements in this field, there is a need to make the necessary changes in the plug-in API first: plug-in settings implemented in a generic way, so that they could be saved and later restored, etc. See: https://bugzilla.gnome.org/show_bug.cgi?id=101604 . Not that it's related to your project.

The md5 checksum is calculated after object is loaded. Each tagged object implements GimpTaggedInterface, including method get_checksum (). Therefore, its internal data is used to calculate the checksum, which means different implementation for each resource type. For resource sharing it might be better to calculate md5 checksum on raw file data. However, not all resources are physical files, for example, generated brushes. There has been some effort to create a common tag storage format, see http://create.freedesktop.org/wiki/ResourceTagging . It would be used by graphic applications for tag storage and put in resource packages. There are some ideas, that resources and tags could be shared among graphic applications. However, there is only discussion where shared tags and resources could be put, not how some applications access shared tag list concurrently. There are quite a few things to decide before something can be actually implemented.

[Gimp-developer] Resource tagging: future development
Hello, How do we imagine resource tagging in the future GIMP versions? It is already usable as it is, but there are many ideas which may help to make it better or worse. First of all, multiple selection in resource windows. There is not much discussion about it, as some time ago we decided that it is important. I am working on it and it should be ready eventually. It is possible to consider multiple selections for other windows as well (layers, etc), but as Sven stated, it may be opening of can of worms (therefore, later). Considering how tagging could be integrated in other similar applications and shared between them, some new ideas were suggested [1]. Currently tag in GIMP is a simple text string. Therefore, when switching LANG, the tags do not change (strings translated for user's locale are installed once on the first run). It was suggested to make tag a complex object, which contains all the translations all the time: tag keych/key label xml:lang=ensee-aich/label label xml:lang=esche/label /tag The advantage is that tags would be translated correctly whenever user changes language. It is worth considering to share tags between various applications. In such case tags would have to be stored in some shared directory. Also, it is not entirely clear how multiple applications could read/write the same XML file without ever corrupting it? Suggestions please. What resource tagging in GIMP could be in 2.8 and in the later versions?

Edit action should be available for writable ones and Duplicate edit(possibly a quiet one) for non-writable ones and should be different from tweaks you can save in tool presets. Let me extend your idea a bit. Every time selecting a resource, a copy of it could be created (in memory, not on physical file). User could edit resource in any way she likes without affecting originally selected resources. GIMP could actually maintain a current-session-brush, current-session-pattern, etc.: when finishing session save currently selected resources (one for each resource type). When starting session only one resource for each type would need to be loaded in synchronously. All other resources could be loaded in background (improve startup time). ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
[Gimp-developer] Default tags for GIMP resources
Hi, As you might already know, GIMP from next version will allow to tag resources (brushes, patterns, etc). It would be nice to create a default tag set for resources provided in a standard GIMP distribution. If someone would like to volunteer, there are following options to create (possibly partial) tag set: * (easier) edit tags from GUI or tags.xml (found in $HOME/.gimp-2.7/tags.xml) file directly and send the tags.xml file to me and I could take care of updating the necessary files in source tree. * (harder) edit gimp/data/tags/gimp-tags-default.xml.in directly. File structure is pretty simple and each entry should look similar to this (resources are already generated, only tags need to be added): resource identifier=gimp-brush-clipboard checksum=157dcef48665ab465439cfaf10d6feeb tag _thetagtest1/_thetag /tag tag _thetagtest2/_thetag /tag tag _thetagtest3/_thetag /tag /resource If you have any questions, feel free to ask.

There were thoughts to assign default tags (which are neither assigned nor removed by users), such as resource name. Perhaps they could even be translatable. However, it is not obvious how it would be better to implement such functionality. I think resource distribution with tags assigned is one of the questions which should be addressed before GIMP 2.8 release. When GIMP detects new resources, how can it find tags for them (possibly translated) ? It also would be nice to allow user to drag-and-drop resource pack (*.tar.gz or similar) so that all resources with tags assigned would get installed. 2) When a user clicks the refresh button in the palettes, gradients, brush dialog or a script uses any of the 'gimp-*-refresh' procedures, what if gimp would re-read the tags.xml file at that point. That is a good idea. It should probably not reread, but merge with loaded tags as user might have made changes both from GUI and manually in tags.xml.

Re: [Gimp-developer] Tagging of Gimp Resources project status
Hi, On Mon, Jul 14, 2008 at 3:45 AM, David Gowers There is probably a need to import tags when adding a set of patterns. As in, person A packages up eight patterns into a .zip file; They've tagged these patterns with a few things that make universal sense (eg 'stone', 'stippling', or 'hi contrast'). It would help persons B,C and D (users of these patterns) to be able to import tags for those patterns from an existing tag-cache.xml file. This is particularly useful as the number of resources in the packages increases, for example my package of dithering patterns (http://gimpstuff.org/content/show.php/dithering%2Bhalftoning+patterns?content=81817) could definitely benefit from it. I am assuming that tag-cache.xml can easily be filtered by a script to contain only information about the items that are being distributed. So I envision a package containing something like blackgranite.pat diamondstippling.pat electricity.pat mypackagename-tags.xml and when the user initially unpacks the package, they import the tags. If they later want to recover the tags (since they may have deleted some of them from their own tags.) they can import the tags again. Do you have a plan to address importation of tags? It is planned to create a platform independent resource file export and import functionality. One user exports some resources to a package (tags associated with resources are also stored in the package). Other user can import resources from the package together with their assigned tags. I'm sure you have a plan to provide tag renaming -- this would be helpful for i18n, allowing a person to easily rename the original tag to something in their preferred language. eg 'stippling' - 'miksiĝi desino' Yes, it will surely be possible. Do you plan to implement NOT filtering? as in 'dithering -diamond' filtering for patterns tagged 'dithering' that are not tagged 'diamond'. I haven't thought of it yet but it seems a good idea. Also, currently there is only AND search in tag queries. Maybe it would be good to add even more flexibility to advanced users. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
[Gimp-developer] Tagging of Gimp Resources project status
Hi, Tagging of Gimp Resources project is an attempt to make it easy and efficient to organize Gimp resources (brushes, patterns, gradients, palettes). Currently the project is already somewhat usable, allowing user to assign tags, filter resources on selected tags, preserve tags between session and more. Screenshots [1] and [2] show how resource (brush, etc) docks look. As you can see, there are two tag entries: the one on top is to filter based on selected tags, on the bottom is for tag assignment. Tags can be typed with keyboard [1] (specifically for tagging a special autocompletion was implemented: autocompletes tags even in the middle of tag list, doesn't offer already selected tags, etc) and selected with some pointing device [2] (popup window stays open to allow multiple tag selection, it can be closed by clicking somewhere outside). Tags cache is stored in tag cache file (~/.gimp-2.5/.tag-cache.xml). The file is user editable, but that is normally not needed. Should user rename or move resource file(s) (brushes, etc), tag cache would detect changes based on file contents and correctly remap tags. Source code is available: svn://svn.gnome.org/svn/gimp/branches/soc-2008-tagging. Questions, comments and recommendations are appreciated.

So you can play with it in any way you like without breaking the original brush (which could be a read-only file, btw). Workflow could be something like the following: 1. Select a brush. A copy of it is created transparently to the user. 2. User can easily edit the brush for her needs. 3. Paint something 4. (optionally) Save the brush to disk. 5. Select another brush.

Hi Torsten, Some gimp plug-ins provide random seed value to user. This way user is able to play with the random value and to reproduce the same effect later, i.e. for tutorials. I am aware of that. The point is, that the function is a random but - according to it's documentation should behave identically for identical images.

Is it possible that one physical file could represent more than one resource? Let's say, some file format of other application which contains multiple brushes. Or some file format which contains multiple types of resources (brushes, patterns, etc). If such case should be handled, we could look at such file as some special kind of directory: /home/aaa/_favorites.col#brush1 This way it should be possible to handle various collection formats from other application. About sharing resources: There was a suggestion, that when user want's to share resources, they could be exported to some kind of archive. If collection handling would be supported, it would be possible for user to access archive directly and for administrator to put some archives to read-only network folder and user could load those resources without the need of extracting and copying to local folder. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

If for some reason a user's tags database gets corrupted, it will be a major disaster. I don't see any disaster. Here is one possible solution: store some sort of checksum (let's say, MD5) together with filename in the database. Let's say user renames file. If new filename is found with the same checksum, simply change the filename in database and that's it - you've got completely correct database once again.

Re: [Gimp-developer] New Splash for 2.4
Interestingly enough, I could never think of a splash screen that would be made for one version (2.4) and imposible to rework for other (2.6). You proved it's possible :) Nonetheless, The Gimp allows everyone to change default splash screen, so you can still make it available to the others. What concerns brushes, I think it would be nice to have links to all known brush, pattern, etc. pages in one central page (or even have resource database).

Do other plug-ins show the same behavior for you? This sounds like a bug in your plug-in. Is there perhaps an idle handler or a timeout still running?

[Gimp-developer] Solving Bug 356716 – GimpZoom Preview is broken in some plug-ins
Hi, Some plug-ins which are left, are not so easy to fix, so some discussion: * jigsaw -- looks like lot of code would have to be changed to make it work with GimpZoomPreview correctly. However, I don't understand why this plug-in would need zoom preview at all. It doesn't do anything that someone would like to check at high zoom level. My suggestion: use GimpPreview instead. * polar, whirlpinch -- both need fetching pixels. Of course, it's possible to ask core to scale down some part, but I don't think we would like to do that for each pixel. Efficient solution would be to scale small regions (tiles) and cache them. For example, lens is doing that. However, it is not very easy to implement (or copy paste from somewhere) such functionality and I think such functionality should be provided by core. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Hi, Save for web plug-in is getting closer to usable state (version 0.18.0 so far). (For those, who got 0.15 version please update to recent, as it had saving bug.) The plug-in now has most of the stuff that has been suggested as improvement on this mailing list.

Re: [Gimp-developer] GimpImage to GdkPixbuf
On 3/23/07, Sven Neumann [EMAIL PROTECTED] wrote: What you are asking for is currently not possible. There are some ways to get something close though. It would help a lot if you could explain what exactly you want to achieve. We could then see if there are already ways to do that or if a new API is needed. The first idea was that you can render all pixels of image on GdkPixbuf once, and then it is very easy (and both fast) to display GdkPixbuf zoomed, scrolled, etc, on GdkWindow. (Eliminate complexity and add flexibility :) I know that this approach wouldn't work for very large images and it is not useful for everyone, so I thought of something more general: gboolean gimp_image_render_to_drawable( GimpImage image, GdkDrawable *drawable, int dest_x, int dest_y, int dest_width, int dest_height, double offset_x, double offset_y, double scale_x, double scale_y, int overall_alpha, int check_x, int check_y, int check_size, guint32 color1, guint32 color2); (most arguments mean the same as in gdk_pixbuf_composite_color()). This would render gimp image (whole or part) on GdkPixbuf or GdkWindow, which should be enough to meat any rendering needs on custom widgets. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer

Hi, What's the best way to render gimp image to GdkPixbuf (which in turn can be rendered to GdkWindow)?

[Gimp-developer] GimpZoomPreview usability
Hi, It uses GtkDrawingArea. ... I don't see why you couldn't implement cropping with one of the GimpPreview widgets. I tried to use GimpZoomPreview instead of GtkDrawingArea and want to tell you what I have found out. As I understand it, GimpZoomPreview is designed to be very efficient for previewing various filters (in terms of required processing memory). Unfortunately, it doesn't seem very usable as one might expect. For a large preview widget uses area not larger than original image dimensions, so when you zoom in you see image only in that area and large parts of widget outside image area are drawn in background color. Moreover, it becomes unacceptably slow when scrolling. The design for small previews just doesn't seem to support large previews well. Therefore, chose GtkDrawingArea. BTW, is there any way to use gimp quick navigation widget with GtkScrollingWindow or ...? In addition to this, GimpZoomPreview doesn't seem to work well with filters either. As far as I know, only nova.c (Supernova) uses it correctly, but it only renders based on a single selected point (it doesn't have to read analize pixels, it only renders on them). If I understand GimpZoomPreview correctly, a plug-in has to scale pixel data outside preview viewport itself (it would be much harder to work if source destination layers would have different dimensions). This is not a very easy task, if you don't scale the whole picture, but only required parts (for efficiency). In conclusion, either I don't understand GimpZoomPreview (in that case some explanation would help) or its API should be improved to make it more usable.

[Gimp-developer] 32bit BMP appear blank
Hi, This is a summary of Bug 352262 – 32bit bitmaps (*.bmp) appear blank ( http://bugzilla.gnome.org/show_bug.cgi?id=352262 ) which as Sven said is important to be settled before releasing 2.4 version. After bmp plug-in has been updated it, among other things, started parsing bytes which were thought to be alpha channel. When bitmap contained valid alpha data in these bytes (which can be created with PS or some other app), this feature worked as expected. However, when bitmap was saved in 32 bit format without alpha, all those bytes became 0. As the result, image appeared completely blank on the screen. The main question: should those bytes be ignored (as it is done by many applications) or should some workaround be used (in case we want to support 32bit bitmaps with alpha channel)? Unfortunately, we were unable to find any official documentation dealing with the problem. Programming Windows, 5th Edition (Charles Petzold - MS Press, 1998) tells that those bytes should be 0. In other words, they should be ignored while loading and set to 0 while saving. P.S. Results of the discussion could be useful when solving Bug 65534. ___ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
