* app/gegl/gimpoperationpointlayermode.c: Implement a bunch of layer modes. Use the exact SVG 1.2 formula for layer modes that have a counterpart in SVG 1.2. Don't clamp the result to [0..1] for Dodge and Burn though as we don't need to. Maybe we *should* clamp from a compositing point of view, I'm not sure. Also reformat the code a bit for readability. Keep in mind that we now treat the opacity of all layers the same indepentant of the layer mode. That is why most of the new implementations doesn't work the same as the legacy ones when transparency is involved, only when the layers are completely opaque. Another important property for all layer modes implemented below is that compositing onto complete transparency gives the same result as if the layer would have been in Normal blending mode. The status of the new layer mode implementations compared to the legacy implementations is as follows: Completely works the same: o Behind Works the same for 100% opaque layers: o Multiply o Screen o Difference o Darken o Lighten o Dodge o Burn o Hard Light o Subtract o Divide Works different but similar: o Overlay Work in progress: o Soft Light svn path=/trunk/; revision=27409 |

------------------------------ GNU Image Manipulation Program Development Branch ------------------------------ GIMP 2.7 replaces earlier GIMP 2.x versions. It is advised that you uninstall them before installing GIMP 2.7. If you want to keep your older GIMP 2.x installation in parallel to GIMP 2.7, you have to choose a separate prefix which is not in your default library search path. Otherwise your GIMP 2.4 or GIMP 2.2 installation will start to use the new libraries. You have been warned. If you think you found a bug in this version, please make sure that it hasn't been reported earlier and that it is not just new stuff that is still being worked on and obviously not quite finished yet. If you want to hack on GIMP, please read the file HACKING. For detailed installation instructions, see the file INSTALL. 1. Web Resources ================ GIMP's home page is at: http://www.gimp.org/ Please be sure to visit this site for information, documentation, tutorials, news, etc. All things GIMP-ish are available from there. The automated plug-in registry is located at: http://registry.gimp.org/ There you can get the latest versions of plug-ins, using a convenient forms-based interface. The latest version of GIMP can be found at: http://www.gimp.org/downloads/ 2. Mailing Lists ================ We have several mailing lists dedicated to GIMP user and development discussion. There is more info at http://www.gimp.org/mail_lists.html Links to several archives of the mailing lists are included in that page. Gimp-announce is a low-traffic list with announcements about new releases of GIMP and plug-ins. Gimp-user is a mailing list dedicated to user problems, hints and tips, discussion of cool effects, etc. Gimp-developer is oriented to GIMP core and plug-in developers. Most people will only want to be subscribed to gimp-user. If you want to help develop GIMP, the gimp-developer mailing list is a good starting point. There is also a mailing list, "gimpwin-users", dedicated to users of the Win32 port. To subscribe, send an empty message to gimpwin-users-subscribe@egroups.com You can also use the web interface at http://www.egroups.com/group/gimpwin-users/. Note that as this mailing list is hosted on egroups.com, the messages from the list contain relatively unintrusive and easily ignored advertisements at the end. But if you are absolutely allergic to ads, don't subscribe. 3. IRC ====== And finally, for the real junkies, there is an IRC channel devoted to GIMP. On GIMPNet (a private free software oriented network) there is #gimp. Many of the developers hang out there. Some of the GIMPNet servers are: irc.gimp.org:6667 irc.us.gimp.org:6667 irc.eu.gimp.org:6667 4. Customizing ============== The look of GIMP's interface can be customized like any other GTK app by editing the ~/.gtkrc-2.0 file or by using "themes" (ready-made customizations). For downloadable themes and further details, see http://gtk.themes.org. Additionally, GIMP reads ~/.gimp-2.7/gtkrc so you can have settings that only apply to GIMP. Included is a set of keybindings similar to those in Adobe Photoshop. You can find them in the ps-menurc file. To use them, copy this file to ~/.gimp-2.7/menurc. You can also manually change the keybindings to any of your choice by editing ~/.gimp-2.7/menurc.
