SuSE, Mandrake and Red Hat permit a pretty much unattended install. Each will permit you to select a standard install and move forward. You will still have to answer questions regarding your hardware, such as monitor, mouse and possibly video card, but my latest efforts with both Red Hat and Mandrake, have found that both identified these devices properly and all I had to do was confirm. I've got Mandrake 9.0 installed on 4 machines, and all I needed to know about the monitor was the make and model, which is no more then required for a windows install. Each monitor was automatically detected properly, so all I had to do was verify that was correct and in all cases it was. These monitors range from a 20 Viewsonic to couple of relatively old 14 (Dell, Panasonic, Packard Bell). As far as bloated, Mandrake will permit you to choose what you install from various levels: workstation vs. server specific type of workstation (development env., internet client..) install by individual packages. Our local LUG had a demonstration of SuSE 8.0 install and it went flawless, on a machine for someone who had never used Linux. He was watching DVD movies by the end of the presentation. I would say you are safe going with Red Hat, Mandrake or SuSE. Of late I've been running Mandrake, although I have two machines on Red Hat and one on SuSE. I also just purchased SuSE 8.1 and plan to check it out. Finally, both my 11 year daughter and my mother-in-law are using Linux for their primary computing solution. My daughter installed her own Red Hat, but I was tier I support during this process. :) -- Until later: Geoffrey [EMAIL PROTECTED] The latest, most widespread virus? Microsoft end user agreement.

[Gimp-user] GIMP Image Size Limits
Under Windows I am running into a problem where the GIMP's pixel buffer seems to hit a 2GB file size limit when my gray scale TIFF image files excede roughly 400KB in size. I'm guessing the buffer requires 5 bytes per pixel (RGB, transparency, ?), even though all of that isn't really needed for my images. I need to work with these images absolutely ASAP. Because all of the machines involved are running Windoze, I was hoping to stick with that. However, it's starting to look like that is a hopeless cause given my poor porting skills and the apparant lack of interest of most gimp developers in addressing this problem under Windoze (at least in the near term). So, I'm starting to consider using Linux instead, and have two related questions: 1. Can anyone out there positively confirm that running the GIMP under a fairly recent version of Linux would avoid any inherent 2GB pixel buffer size limit? I can provide some images for testing if anyone would like to volunteer... 2. Would anyone out there care to suggest a readily available commercial Linux distribution that is extremely easy to install, learn, and use for unsophisticated users with primarily Windblows experience? Thanks in advance for any help. s/KAM ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user
Re: [Gimp-user] GIMP Image Size Limits
I am curious about your file sizes though: 400 KB doesn't sound all that big; actually, that sounds pretty small. Also, I'm not very technical so bear with me, but isn't 5 times 400 KB about 2.0 MB?

Whew! That would be a test of my system! Like I mentioned earlier, the largest files I ever tried to work with were about 100 MB, and although it worked it was too annoying to bother with.

Re: [Gimp-user] GIMP Image Size Limits
Kevin, I may be able to save you the trouble. While I was waiting, I went ahead and just tried to make some 400 MB tiff files. I got as high as 273MB and my system didn't like it, but it did it. Above that, the GIMP just died and went away - literally! I set the preferences so as to allow as much free memory as possible but that's the best I'm able to do. So I wonder, is there some sort of ~300 MB limit with tiff files, or is it just my system, or the way I had things set up. Don't know. I was using color tiffs if that is useful.

Hi Fred - Please don't wait around for me to upload the test image that I mentioned previously. In attempting to get this ready for you, I have encountered some unexpected behavior that I am presently evaluating. I am able to open and work with larger files than I experienced previously. Something must have changed on my system, but I have no idea what it could be. Suffice it to say at the moment that it doesn't look like the GIMP has a memory limit that affects my usage under Windows after all! I'll get back to you and the list later with more details once I'm certain that I can believe what seems to be happening. Thanks once again for offering to help.

Re: [Gimp-user] GIMP Image Size Limits
Hmmm, Ok, here is what seems to be happening: When the size of the vertical axis (I didn't test horizontal) exceeds somwhere around 2250 inches, the gimp dies or locks up. It doesn't seem to matter what the size of the file is, and it doesn't matter how many pixels there are. Using File - New, both 1024 x 162000 pixels at 72 dpi and 1024 x 45 pixels at 200 dpi work fine, while both 1024 x 163000 pixels at 72 dpi and 1024 x 453000 pixels at 200 dpi fail. I have no idea exactly what could be causing this, but obviously an overflow or overrun of some type seems likely. Any gimp developers out there care to take a look at this?

But it would be fun to try a 400 mb file. I could just set the preferences parameters really high, close down everything else and see what happens. It will take a few minutes just to download a 400 mb file! On Thursday 09 January 2003 00:11, Kevin Myers wrote: Sorry Fred and all, my apologies, 400KB was a serious typo.

Also, I'm not very technical so bear with me, but isn't 5 times 400 KB about 2.0 MB? What am I missing here?

I'm guessing the buffer requires 5 bytes per pixel (RGB, transparency, ?), even though all of that isn't really needed for my images. I need to work with these images absolutely ASAP. Because all of the machines involved are running Windoze, I was hoping to stick with that. However, it's starting to look like that is a hopeless cause given my poor porting skills and the apparant lack of interest of most gimp developers in addressing this problem under Windoze (at least in the near term). So, I'm starting to consider using Linux instead, and have two related questions: 1. Can anyone out there positively confirm that running the GIMP under a fairly recent version of Linux would avoid any inherent 2GB pixel buffer
