Re: [Gimp-user] changing background colours
What are the advantages of RGB vs. indexed? I'm afraid I know nothing about this. You can use filters on RGB :) also index color (gif files) only have a maximum of 256 colors in the image, this is configurable. the-part-I-am-about-to-get-wrong rgb colors have 16,000+ colors. I think this varies between file formats and saving parameters (but way more than 256 ;). Jeff On Mon, May 14, 2001 at 02:15:20PM +0100, Rasputin wrote: * Michael P.

[Gimp-user] Putting together scanned parts of a map
Hi! I am using Gimp for quite some time now with its basic functionality. Now I did run into a new problem, for which I would like to get some suggestions on 1. how to do it 2. how to do it efficiently :-) I have scanned a map with my A4 scanner, but as the map is quite large, it did take several scans. Now I try to put the thing back together. The identification part is simple, because the map does contain a rectangular grid, so that cutting on a grid line is possible. I can also rotate, so that the grid is looking rectangular, but: * the scanner (a not very expensive Microscan model) is not working completely parallel, so that when the left and lower boundary are fine, the right boundary is changing by 10 pixels to the left (on 3000 for the height). How can I best deal with the distortion? * Once I have these rectangular pieces, how do I best put them together to one large map. By now I have scanned with 300dpi and the grid lines are at a disctance of 2cm, so I can calculate at which absolute positions I have to put the parts together, but I did not find a menu to put the data into... (I know that 300dpi is a lot, but I rather scan with high resolution and compact it later...) I do have a Duron 800 @ 256MB main memory, so that I can play around a bit with large graphics as needed. Any ideas? Lutz PS. For the background: I do own a GPS (a Garmin GPS12 for those interested) and can do route planning with the Touratech QuoVadis software (http://www.ttqv.de/, I really love free software and Linux, but there is nothing comparable for Linux, so I have to boot to Windows to use it...). The map is a Bla Kartan 1:10 for the south of Sweden. It does have a 2cm (=2km in reality) Swedish Grid printed on it which is supported by the Garmin device, so that in Sweden on the bycicle I'll have a good navigation method, but I would like to prepare the routes in advance. As GPS is offering a high accuracy, I would of course also be interested in digitizing the map accurately as well. -- Lutz Jaenicke [EMAIL PROTECTED] BTU Cottbus http://www.aet.TU-Cottbus.DE/personen/jaenicke/ Lehrstuhl Allgemeine Elektrotechnik Tel. +49 355 69-4129 Universitaetsplatz 3-4, D-03044 Cottbus Fax. +49 355 69-4153 ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

Yes, it is not the latitude/longitude grid. The swedish grid (based on Gauß-Krüger) is similar to the UTM grid, see http://www.bacher.de/abc/g.htm#GaußKrügerGitter http://www.maptools.com/UsingUTM/index.html http://www.joe.mehaffey.com/utminfo.htm Of course, such projection is only valid within certain limits: http://www.colorado.Edu/geography/gcraft/notes/coordsys/gif/utmzones.gif (sorry if these links are off topic for graphics, but they are related to my problem :-) Therefore: yes, this thing _should_ be rectangular...

[Gimp-user] gimp swap file
I swear that somebody asked a question about the gimp swap file and how it continues to grow even after a new image has been opened (after the previous one has been closed), but I didn't get the posts regarding the answer (if there was a response). What can I do to get the swap file to automatically refresh after I close an image - so I don't have to close and re-open gimp for every new image I wish to work on? Thanks alot in advance. -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
