Simple jpg question
I have been scanning photos with a flat-bed scanner, then cropping each picture in the scan into separate files. When I saved the separate files, I moved the compression-quality to 1.00 (replacing the default .75), hoping that I would not loose any more quality. I was not sure if saving a file multiple times with .75 would continuously degrade the image. I figured that I would wait until all of my modifications are done for each image before I save the final image to .80 quality. But, I am finding that my disk space is drastically declining. My question is: Can I crop the images into separate files, saving them at .80 quality, then do modifications and save them again (into a separate file *.modified.jpg) at .80 quality without loosing quality after each save? Thanks alot for all of your help. -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED]
Photo Archive
Hi, Is there a utility to create photo archive, like Image Alchemy did before 6-7 years? How it works: it scans the directory for know image formats, he make one (or more) big picture (mostly 1024x768) picture, he put thumbnails on this big picture (save image ratio, but possibly reorder the images to fit to the page) When this page(s) was created, it was clickable, to the original images, just like image maps in HTML. The (one) big picture is for mostly CD-ROM archives, what is not quietly effective for large amount of small (thumbnail) files. best regards, tamas

Since everyone's talking about scripts filters... Does anyone know of some script/filter to create sin/cos curves? I want to be able to choose the tool i want to use with it, set the "step"amount between every mark and then the sin/cos variables + decimals to get some tweaked curves (which ofcourse does not end up where it started from the beginning). I'm not sure if this is quite what you want but you can get perfect sine curves by doing a repeating sinusoidal gradient and using that as a displacement map. --Ben Or do i have to get myself some old pascal vga-lib for linux and do this myself? =) (That was a "i don't want to do that" sentence).

Re: Photo Archive
Try these. Some are actual programs, but most are web-based (generating html, php - gallery generators). There are others out there. I just did a simple search on linuxlinks.com for "photo" Also, try www.sourceforge.net (more updated than linuxlinks.com), or freshmeat. Good luck. http://www.madasafish.net/~aramis/ http://www.cfutura.com/fotos/ http://toasty.mcs.muohio.edu/~moosejc/software.html http://www.nachoz.com/gallery/ http://dougiamas.com/photoalbum/ http://photo.sourceforge.net/ On Thu, 21 Sep 2000, you wrote: Hi, Is there a utility to create photo archive, like Image Alchemy did before 6-7 years?

adjust /import layers function
Hello everybody, anyone to help me? I found two functions in the GIMP manual, but cannot find them in the program itself. In the section layers on bottom of the page the functions "adjust layer" and "import layer" are desrcibed. I tried to find them in the program itself, but could neither locate them in the normal pop-up menu nor in the layer pop-up menu in the layerschannels dialogue. So: where can I find them. Thank you very much for your help, S. Koller -- Sent through GMX FreeMail - http://www.gmx.net
Re: adjust /import layers function
Are you using the most recent version of gimp (1.1.25)? Renzo -- -- LINUX: Reboot once a year...just for fun. -- Take a look at www.gameoefter.org

Re: Filters...
Have you messed with gnuplot? After reading the help (which is quite extensive) you can figure out how to modify your sin curve as you see fit. When you get something you like, just output to a .gif file and play with it in gimp. Certainly easier than coding in pascal ;)

Hi, I'm about to scan some images today! I'll save the scan of all the images as one uncompressed TIFF and FTP it to my linux box at home. When I get home tonight I'll open the large image and cut it up into the smaller images. I'll save each one as a .xcf.gz because I want good quality copies. (pristine without any compression damage) Over the weekend I'll prep each image for the web site and save'em as .jpg. Later on, if my client asks me to modify one I'll return to the .xcf.gz version because it has never been JPEGed and it has no damage. This is the preferred way of doing things... NEVER compress an image thet you plan on editing in the future. Lossy compression should be the very last step before you publish an image. I do make an exception when I use my digital camera. I have a Nikon Coolpix 950 and it will shoot in an uncompressed TIFF format but the images are 5MB each and my 36MB compact flash card fills up fast. Until I can afford to buy a large 200MB compact flash card I'm shooting in "fine" mode. (full resolution JPEG with minimal compression) In "fine" mode the images are around 700Kb. If I do anything to edit one of the digicam images I revert to the .xcf.gz / .jpg system described above. Hope this helps. -- Jon Winters http://www.obscurasite.com/ "Everybody loves the GIMP!" http://www.gimp.org/

Re: Does this filter exist?
[EMAIL PROTECTED] (2000-09-21 at 2210.43 +0200): I should also mention that I would scale things up only as a last resort. If possible re photograph or re scan at a higher resolution. Say I have a 640x480 JPG I use for desktop background. I'd like that to be 1152x864. I can't simply rephotograph or rescan it. Then you are out of luck. Gargage in, garbage out. Pixels can not be created from the void, only calculated based in the original ones (calculated, not copied). If you want extra quality, I would select Cubic in the Scaling entry of the Environment category of Preferences window, it is slower, but better. GSR

The easiest way to scale up copyright violations is to: Open the image Right mouse click and select: Image Scale Image... Then adjust the New Width and New Height and hit [ OK ] If you try to scale up beyond around 10% of the image size or if the image is very small things will degrade quickly.

exported paths - xfig etc.?
Hello out there, I gladly discovered the path feature of (very promising!) gimp 1.1.25. One question: Does somebody have an idea how to convert a couple of exported path files to a file in one of the common vector graphics formats (or is there already a utility which does the job?!) -- it seems to me that necessary information is provided in the exported textfile, but I'm not too experienced in those things ... however, to do it myself, I would like to have a format description of the exported path files (e.g., what does Type 1/Type 2 mean?). What I want to do is the following: I loaded a satellite image and digitized some areas in a separate layer, saving them as paths. Now I want to make a (vector based) map ... I'm a little bit too lazy to do it with grass ... Can somebody help? If so (*many thanks* in advance ;-), please mail me directly/CC: me, I'm not on the list at the moment ... Many thanks for your attention, Ulf P.S.: ... and does somebody know how to measure not just distances but area of a selection? -- === Ulf Mehlig[EMAIL PROTECTED] Center for Tropical Marine Ecology/ZMT, Bremen, Germany ---
