[Gimp-user] Tips on enhancing photos
Here are two photos that I have that I scanned when I was with my dad in Indiana in January. I (as a baby) am on the left, and my dad is on the right. These pictures are all that we have left of that time period (early 1970's) - the others were lost. This photo is a high resolution scan of two pictures from my dad's wallet. And, as you will see, they are really ragged. I am hoping that some of you are sophisticated and deep with the gimp, and can give me some tips on how I could enhance these pictures to look as new as possible.

[Gimp-user] jpeg comments
I am working on a photo gallary for my web site, and I am looking for a way to extract a the comment from the jpeg files as a text string for the web page. I plan on doing all of this in perl. Can this be done in perl? If not, what can I use to get the job done, for pages generated on a virtually hosted web site? -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[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
[Gimp-user] Rotate
Am I missing something, or is GIMP really limited in the ability to rotate an image? I nice that it is only limited "right angle", 180, 360, etc. I have been saving temp images to disk and using ImageMagick's Display to do the rotating, then opening the edited file back into GIMP for further processing - and I am doing this with jpegs - which means that RGB data is changed each time I save the file. -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
Re: [Gimp-user] Rotate
Found it! I see that I can use a grid and spin it around. This works great! Now, is there a way to align the rotation to a guideline? For example, I open up a scanned photo and the photo is on a white page, but the photo is crooked. I want to align the photo so it is streight. I found that using guidelines helps alot, so I can get this perfect. How can I use the rotate tool, combined with guidelines, to achieve this? Thanks alot!

Re: [Gimp-user] optimizing image for internet using GiMP
What would happen to a jpeg image if I open it up and save it at 75% quality. Reopen the image and save it again at 75%? Would there be loss to quality? Seems like it would. Once I opened a picture I saved at 75% before and saved it at 100%. The file size increased. I don't understand that. There are times when I want to open a jpeg just to resize the picture, and then save it again - but I don't want to lose any more quality - and I don't want to increase the file size compared to what it was before. How do I go about handeling this? Also, where can I find documentation on the web where I can lern all about jpeg? Thanks in advance.

In brief: GIF is a simple indexed format, one byte per pixel, which limits the total number of colors to 256 maximum. It will allow for on/off transparency; one color can be called transparent. JPEG allows for millions of colors (3 bytes per pixel, actually, one each for Red, Green, and Blue), but its compression scheme is lossy, trading fine color detail for reduced size. The usual rule of thumb is GIF for line art and pictures with large areas of a constant color, JPEG for images with lots of detail such as photographs. Nothing really beats loading an image into the Gimp and just playing with it. There's always new stuff to be discovered. -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
Re: [Gimp-user] Re: Re: Altering comment in jpegs
Thanks, James. I found wrjpgcom On Friday 06 April 2001 19:56, you wrote: I just tried out opening a jpeg with a text editor (vim), and changing the comment manually. This works fine if you make the new comment the same length as the old one. If the new comment is longer, a warning is issued when opening about extraneous bytes, and if the new comment is smaller it doesn't open. This can be fixed by opening with a hex editor, and changing the byte before the comment: xxd myfile.jpg myfile.hex change the line: 010: 0048 fffe 0007 4865 6c6c 6fff db00 .H..Hello... to: 010: 0048 fffe 0004 4865 6c6c 6fff db00 .H..Hello... convert back to binary: xxd -r myfile.hex myfile.jpg Then change "Hello" to "Hi" with a text editor like vim. And I figured that out without even looking at the documentation! I bet it would only take a little C to make an automated jpeg comment changer. Oh, and upon some looking around, there's one right on my system: wrjpgcom. So read the man page on it and see if that's what you want. -James Smaby ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] Altering comment in jpegs
What is the best way to go about altering the comment string in a jpeg file? I don't want to have to open the file, edit the comment, and then save the file again, in fear of loosing more image quality. Even a command-line utility is acceptable, if GIMP doesn't have this feature. -- Rick Rosinski http://rickrosinski.com [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
[Gimp-user] OT: Virtual Screen Resolution and XFree86 4.0.3
I have successfully set up XFree86 4.0.3 with some virtual screen resolution, but I had lost lots of desktop space as compared to XFree86 3.3.6. In the past, I was able to get the mode "640x480" and a virtual resolution of 2400 x 2000 to work well with my Voodoo3 2000 AGP 16MB card. But, now - with 4.0.3, I have lost half of that vast desktop "real estate", and I am stuck with a virtual resolution equivalent to about 1024x768. I have tried to work this out for a while, and I have posted to other lists, to no avail. Nobody seems to know on those other lists - even on the XFree86 lists. The bottom line is: I want the same functionality in 4.0.3 as I had in 3.3.6. I have included my XFree86Config file from /etc/X11. Can somebody help me out?
