Re: [Gimp-user] Seeking better "green screen" method
Hi Have tried deep-edging the image using the path tool. I find that using that tool works best when removing a backround in an image. It takes a few minutes, though if you have many stamp-scans with the same dimensiona nd edges that single path you spent an hour creating becomes a joy to use because once you have saved that path you can load and reuse it. Here how to do it. docs.gimp.org/en/gimp-using-paths.html docs.gimp.org/en/gimp-path-dialog.html And lastly if you feel you familiar with all that you can visit: gimp.org/tutorials/Drawing_Shapes/ I hope this can be helpful to your work. :) Judah ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

Hey Jay, The first thing I would try is obtaining a set of backgrounds with strongly saturated colors, like colored construction paper, to select background colors that are not present at the edge of the stamps themselves. Then I would turn on the Fuzzy Select a.k.a. "magic want" tool to select the background area by color - with the Tool Option tab open in the dock. Adjusting the Fuzzy Select tool's threshold (way up) might get you where you want to be in selecting the background, and all of it, so that when you fill the selection you will get all of the background with no "halo effect" or unacceptable degradation of the edge of the stamp itself. :o) Steve ___ gimp-user-list mailing list gimp-user-list@gnome.org http://mail.gnome.org/mailman/listinfo/gimp-user-list

If I was going to do an index replacement (aka "green screen"), I'd use a solid background of intense color that won't be present in the item. Then I might: Select the background (with fuzzy select), fill with black. With the selection still active, feather it (to the approx width of the "halo" and then Colors->Desaturate. But it's hard to come up with a workflow without seeing an example. Can you post an example scan with a colored background and "halo"?

Re: [Gimp-user] Seeking better "green screen" method
You can try "Color to Alpha" using a background color not found on the stamp, but you may end up needing to do back-filling under the stamp (draw on a layer underneath it) where it removed a portion, and it probably won't work that well for real-world images (slight variations aren't handled well by the algorithm). You can also use a painting mode of Color to Alpha to only clean up artifacts a select-by-color and removal leaves, but that's more work. The foreground extraction method is intended to do something similar to what you're wanting, but until the new one is ready (see http://www.youtube.com/watch?v=kkQ1r5g49d4) its only a binary selection so you'll not get nice removal of color components and you'll see bleed. You might take a look at the Bluebox plug-in with GAP (you'll have to locate/install the GAP plugins for your platform); haven't used it personally but it seems like it has the right options.

I've found that scanning object once and then rotating the object on the scanner by 180 degrees and scanning again, and combining the image, can help with that sort of object-depth effect. I've used it to get rid of (or reduce) embossed lettering on old engravings for www.fromoldbooks.org for example (also with an Epson scanner). The reason it happens is that the scanner sensor and light have to be at an angle to avoid reflections (including from the glass!). Television cameras don't have this problem.

[Gimp-user] Seeking better "green screen" method
Hi, Gimp 2.6.6 on Ubuntu Linux 8.04. Scanning using VueScan Professional 8.5.20 with an "Epson Perfection 4490 Photo" scanner. Color profile has been built for the scanner using available photo color target from a well-known German source (can't remember name). Almost all my scanning is of postage stamps and related items -- scanning the actual physical objects, not photos of the objects. Problem: The stamps are currently scanned on a black background (for lack of other color possibilities; the final goal is on a black background). After scanning, the background is selected and turned to 100% black to have greatest contrast for the object. When a stamp has a postmark that crosses the edge of the stamp paper, the color of the postmark (usually dark or black) is very close to the color of the scanning background and thus when the background is selected, the selection "leaks" and "follows" the postmark onto the stamp. We have to manually exclude those "leaks" from the desired selection area. Goal: To be able to select the background (for change to 100% black) without any "leakage" of the selection onto the stamp objects AND without ANY non-black color artifacts remaining after changing the selection to 100% black. Attempted Solutions: We have tried scanning on many different non-black background colors and surfaces, but there are always some extreme-edge color artifacts remaining ... leaving a sort of "halo" effect around the stamp object. Some of this could be attributable to the particular model of scanner, though every scanner I have ever owned had a similar problem to a greater or lesser degree. The width of the "halo" usually depends upon which side of the object it is on vs the direction of travel of the scanner device. In television broadcasting it is extremely common for somebody to stand in front of a "green screen" and for the green to be electronically replaced with some image or video, etc. (For example, the weather person standing in front of a weather map.) It is rare to see a green "halo" if everything has been done correctly and if the person is wearing the correct type of clothing fabric. Is there some Gimp method or plug-in or other tool that will better handle this type of use? Recently poster Ron Guilmette discussed his use of "Darla-PurpleFringe.scm" plug-in to remove an artifact caused by a digital camera and subsequent processing. Is there something like that which can be used to remove a color "halo" that results from using a "green screen" approach to scanning? (I would likely have to select different colors of "green screen" so that such colors are not included in the design of the postage stamp. Any advice would be appreciated.

[Gimp-user] Startup problems
Hi there I think I may have posted this question into the wrong thread. Hoping someone can help me. I have become quite fond of GIMP and use it to make posters, images and colouring pages for my classroom. I recently was given a new HP Probook 4530s with Intel Core i5 processor and it is running Windows 7. I tried to download and install Gimp 2.6 but when I start up I get an error saying: The procedure entry point libintl_setlocale could not be located in the dynamic link library intl.dll. On the Gimp FAQ - it says that this is a fault connected to HP machines and that a broken app placed the file in the system32 directory. It also says that I should rename the file and it should work. I am not quite computer savvy - so I would like someone in the know to help me out here. 1. What should I rename the file to? And should I move the file from the system 32 folder to like some Gimp folder? 2. Some other HP user said that renaming the file interefered with some Logon User Interface - I am not going to pretend like I even understand what this means - but it reads as if merely renaming the file caused something else to malfunction. Like I said earlier - I am very naive when it comes to computers and how they work so may I please ask someone who has successfully resolved the problem to talk me through step-by-step (I mean like seriously treat me as if I am someone who has just learned to turn a PC on) on how to fix this problem. I sont even know what to rename the offending system 32 file. Is that intl.dll file the system32 file for windows - or does it contain all the files for Gimp including legitimate Windows files. Uuuurgh - so confusing. As far as I can see when I start up Gimp - all the plug-ins and things like web-browser.exe files cannot be found. I dont know what registry items and all that in-the-know pc speak is all about. I really need my hand held on this. Can anyone help out a naive schoolteacher in Africa with this? Anyone?

Anyone else interested in collaborative working? Hi Edward, I briefly discussed Verse and its future with Jiří Hnídek, its developer, in late 2010. In short, he thinks that using network protocol for sharing has proven to be the wrong approach. So Verse needs a redesign anyway. The other thing is that we are moving to GEGL, a new image processing core, so Verse also needs to be rewritten with that in mind. Øyvind Kolås, the current maintainer of GEGL, can probably explain the right approach better, and AFAIK, GEGL already has bits of architecture for collaborative editing in place, but I could be very much wrong.
