[Gimp-developer] ANNOUNCE: GIMP 2.9.4 released
Hi, We just released the second development snapshot in the GIMP 2.9.x series leading to GIMP 2.10. This is an unstable development preview and might crash or do whatever. If you try it for work, please save your images more often. For a complete list of changes since 2.9.2 please see the "Changes" section below. We will also post more detailed news about GIMP 2.9 on www.gimp.org soon, stay tuned. Happy GIMPing, --Mitch Download GIMP 2.9.4 is available from: http://download.gimp.org/pub/gimp/v2.9/ and from the mirrors listed at: http://www.gimp.org/downloads/#mirrors Please use the torrent, it distributes the download bandwidth across all mirrors: http://download.gimp.org/pub/gimp/v2.9/gimp-2.9.4.tar.bz2.torrent The checksum of the tarball is: 6b3d425a7949110eeb532badedf721f3 gimp-2.9.4.tar.bz2 Overview of Changes from GIMP 2.9.2 to GIMP 2.9.4 = Core: Color Management: - add new GimpColorTransform object to create abstraction from LittleCMS - now color-managed: - layer/image/color palette/gradient/pattern previews - Color Picker tool - color buttons of GimpColorHistory - GimpFgBgEditor, as used e.g. in the toolbox - color selectors - DND widget - painting tools - copying layers/paste buffer between images - Colors applied to images - GimpColorPanel and its color dialog (color widgets in dialogs) - color areas created from menu actions - color management for grayscale images, including setting preferred ICC profile - add fast switching between color managed display and soft-proofing - add a per-image "is color managed" switch and show the image's "is color managed" state in the window title string - add basic support for creating images with color profiles - add "Optimize" options for display and soft-proofing to optionally speed-up rendering at the cost of color fidelity - add Image -> Color Management -> Save Color Profile to File... - improve the naming of generated ICC profiles - add a shortcut to the profile chooser dialog on OS X too - don't let display color management settings affect file import - enable color management when a profile is assigned to the image - enable color management when the image is converted from/to grayscale - pass the right color profile around in gimp_selection_float() - hardcode the CMYK selector's conversion parameters, as well as NTSC parameters in babl/GEGL/GIMP - have all previews track the monitor they are on Core: - add "Select -> Flood" select action - add "Select -> Remove Holes" action - add "Border style" combo to the "Select -> Border..." dialog - do not request xcf compat mode when compat_toggle not sensitive - initialize fontconfig in the background to be able to show a pulsing progress bar when rebuilding the list of fonts (typically, the first time GIMP runs) - fix the Behind blending mode - make Burn mode output match Gimp 2.8 (partial revert of bug 744265) - improve file magic matching - add a custom guide concept - improve updating the statusbar messages and icons GUI: Menus: - move the image-duplicate action next to image-new - add Image -> Color Management -> Color Management Enabled - change "Select _Custom Color..." to "_Custom Color..." - change "Export" to "Export..." in the File menu Dialogs: - include recently used colors in the Dockable Colors dialog - add RGB-based Luminance channel to the Histogram dialog - fix remembering the order of dockable dialogs Preferences: - reorder the prefs categories tree and rename some pages - move "Snap Distance" to the prefs dialog's "Snapping" page - add configuration for undo preview size - clean-up Preferences -> Color Management - add "Shortcut [some modifier] + Mousewheel" for changing pen size Themes: - rename theme "Default" into "System" - add new GUI themes: Lighter, Light, Gray, Dark, Darker Icons: - add icon theme selection and make the icon theme path configurable in prefs - preserve 2.8 pixel-perfect icon theme under the name "Legacy" - add new symbolic icon theme for GIMP - add a scalable icon theme and a configure option --enable-vector- icons Widgets: - add new GimpBufferSourceBox widget and use it in GimpOperationTool View/Display: - fix various bugs related to rotated canvas - make GIMP not ignore 'Maximized' hints on startup in Windows - enable a pulsing progress bar in the splash - make new images jump around much less - fix image position when entering/leaving fullscreen mode - make layer boundary re-drawn correctly on scrolling - make images not appear completely black when images dockable is visible - have all previews track the monitor they are on Tools: Fuzzy Select: - add "Diagonal neighbors" option Foreground Select: - fix ghost brush outline Bucket Fill:
[Gimp-developer] Converting Plug-ins
I'm investigating converting existing plug-ins from 2.8 to use GEGL. It appears that one would implement the calculations in GEGL, leave the interface and parameter input code pretty much as is, and then pass the parameters to the GEGL code from GIMP plug-in code (making two plug-ins, actually). Am I missing something? Handling previews effectively seems like a task better left to GEGL or a generalized GIMP callback than being done in each plug-in. Algorithm question, using despeckle.c as a starting point: The "median" algorithm uses luminance of the pixels around the point of interest, creates a histogram of 256 levels of luminance, throws those below and above a user specified threshold out, finds the median level of luminance, and then chooses randomly from the pixels that have that level of luminance. This would seem to choose a random color with an appropriate luminance from the region. Seems to me this makes the algorithm useful for gray scale images that are not black and white. Only The literature is full of other despeckle algorithms. The code itself mentions 4, including "adaptive" but appears to implement none of them. Handling the following all seem worthy at some point 1) black/white images, 2) maintaining detail and contrast while smoothing larger areas of more closely matching pixels, 3) separating luminance or value from color. Questions: Is renaming for example despeckle to despleckle-median easy to do in the future or is it somehow easier during the initial conversion process? My own preference would be to use a new more specific name in GEGL and keep the old despeckle name for now in GIMP, though adding a method parameter could also work for the GEGL code. If I do take on a conversion, is it acceptable if I include comments explaining the algorithm, or will they just be deleted? If I include comments about when the algorithm seems useful, will those just be deleted? ___ gimp-developer-list mailing list List address:gimp-developer-list@gnome.org List membership: https://mail.gnome.org/mailman/listinfo/gimp-developer-list List archives: https://mail.gnome.org/archives/gimp-developer-list
