hi, i am looking for image merging software in linux (preferebly command line). i have a very big print which i have scanned into pieces (scanner size was not sufficient to scan at one go). i tried google, but no luck. tried gimp but it will have to do it manually i guess. but manually merging them border to border is not possible (due to insufficient RAM- even 2Gb is not enough, it stalls for some time even for a small movement of any image).
so it would be nice, simply to feed these images to a software and let it take whatever time to do the job. the similar software is present in many digital cameras, to be used to make panorama images.
any help is badly needed. thanks.

What kind of images are you trying to merge together? I don't know if scenic images can be merged together automatically. You as the artist determine the merge points in the various frames.
To the best of my knowledge the "similar software," (Windows based) bundled with dig. cameras are not significantly different compared to Gimp. IIRC, you need to provide "stitch" points (manually) on the various frames for it to amalgamate them into a panorama.
Also, if you are running into memory issues with your images under Gimp then try reducing the resolution or color depth and see if it helps. At the same res. and color depth, I suspect you may have the same problem under Windows as well.

JPEG. they are not scenic. its a detail information chart of various parts of an Gulfstream business jet aircraft.

i found some panorama plugins for gimp. will try that.

Use jpg format and from your other reply it appears that you are using the same. However jpegs of low compression levels or 90% quality are still high in memory space. First compress your jpeg to 30% quality. This drastically reduces space usage but its lower quality is hardly noticable to the eye and your pixel resolution will still be the same. I regularly do this to send high resolution images 1024 x 768 by email. However I don't know how its done in linux. I use the 'other' ;) os using 'irfan view'. In your linux software look for the 'save as' option, select jpg as your output file format and if a slider is provided, slide it down to the low quality level.

A split image in a camera is mapped during its capture itself, so in your case of post capture, you will need some mapping software that marks the positions and then creates the full image as per the map. Use a small view level so that you find it easy to merge smaller squares or rectangles and that should reduce the strain on your video processing.

are you talking about on disk memory usage or in memory?
in memory, everything is converted to a bitmap for display on screen.

I meant file size. :)

thanks for your replies. i tried that gnome pluging for merging, it works but its not so good. i mean for simpler images it does the job.
anyways by yesterday evening i got so fed up with this automatic merging thing that i decided to go manually. finally by the dinner time, with gimp, i manage to merge all images by drag an drop.
Try convert [man] from ImageMagick package. $ man convert
"convert -append" merges files vertically. Using a combination of -rotate and -append you should be able to combine all sorts of pieces. Dunno about memory requirements though!!!
