[Gimp-user] scanning electron microscopy
Hi, I just joined the list. My interest in gimp is as a scanning electron microscope user. is there any plugin that allows calibration/scaling of the image pixels to microns or nanaometers. the information i found referred only to pixels/inches.

Try the unit editor. http://docs.gimp.org/en/gimp-xtns-unit-editor.html There appears to be a limitation on the unit editor that prevents it from being used for nanometers. If you type in the scale factor 2540, (which is appropriate for nm), the editor chops it down to 2^16.

You probably want to use Gwyddion instead of GIMP. Otherwise, I suggest that you work on a fixed scale of 1:1,000,000. That's what I usually do when working with AFM pictures in GIMP. Just use millimeters as if said nanometers. Sven ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Bug 119646 – add polygonal selecti on tool
Continuing the discussion on bugzilla (1) I have a suggestion for a possble third way. I remember something being written about vector layers in gimp and found a reference to it at google.com (2). If there was a tool that enabled one to draw vectors, they could be stroked, converted to a selection or converted to paths at the user's will. Although it's not a quick fix to the problem, it does avoid the possible complication that comes with modifying the free select tool (for example, assigning shift to both add-to-selection and draw-straight-line modifiers) or adding yet another select tool that isn't quite free select and isn't quite bezier path.

[Gimp-user] Color temperature modification plugin available!
Dear All, I have just uploaded to the Gimp plug-in repository a plug-in that enables you to modify the color temperature of a photo. I can be used to correct the bluish cast in overcast photos, or even (to some extent) the red cast in photos taken under incandescent light with the camera set to daylight. At least for me, the plugin works better than playing around with the levels and curves menus by hand, in part because the color transformations are done in the linear (rather than gamma-corrected) color space, and use black-body color temperature as reference. Anyway, I had been wishing for a long time for a tool to modify the color temperature of an image, and now there is one! http://registry.gimp.org/plugin?id=8730 I hope it can be useful to others! Give it a try, it has extensive help included. All the best, Luca ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] layer grouping
Is it possible to group layers in Gimp? One problem is linking them, would be nice to link groups and move them independently of each other. Also, I opened a PSD file which has 50+ layers. some named /LayerGroup with no content. -- Anthony Ettinger phone: 408-656-2473 resume: http://chovy.dyndns.org/resume.html Currently available for contract work blog: http://www.chovy.com ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

What are the implications? I haven't read about the MS/Novell GPL 3 thing. There was talk of adding a clause to v3 that would help secure free software against patent trolls in such a way that if Company A promises not to sue Company B for using an infringing algorithm in a GPLed application, that promise has to extend to every user of that application. In other words, if MS promise not to sue Novell over Mono, implicit in that agreement is the promise not to sue me over Mono, regardless of whether I'm running SuSE or something else. Personally, I'm in favour of GPLv3 anyway. All it's doing is closing loopholes that enable distributors to avoid granting me one or more of the freedoms I come to expect from free software.

Re: [Gimp-user] Color temperature modification plugin available!
Thank you, Luka The plug-in seems to work! I have only one problem with it now - it doesn't define a place to be put in the register procedure. I added Image/Script-Fu/Enhance/ before the Convert Color Temperature and could find it :). I use GIMP 2.3.12 on Windows.

Re: [Gimp-user] Color temperature modification plugin available!
This is strange - I defined it so that it goes under Tools/Color Tools for version 1.2 (It used to be Layer/Colors). That's where all the other color manipulation options are... (The script-fu menu seems to be on things other than color manipulation). Can you check which version you are running? Oh btw, I developed this under Gimp 2.2; I have no idea whether other versions of Gimp have different menu arrangements, so that the plugin does not find a home. Let me know...

Ok, it appears exactly where you said. I simply wasn't able to find it there.
