[opensuse] Image resizing?
Is there a Linux utility that I can use to convert a folder of larger images to 480x234, the native size for the digital picture frame my wife bought me? It occurs to me that it probably would be more efficient if I fed it images that are its default size, so that it doesn't need to scale them down. Thanks in advance! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I use this one liner in a shell script do convert photos prior to putting them on the web for a club I belong to. Set the res to what you need and adjust to the type of pics you are converted. for I in `ls -1 *.[j,J][p,P][g,G]`;do convert -resize 640x480 ${I} ${I};echo ${I} Completed;done -- Ken Schneider SuSe since Version 5.2, June 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

That's almost exactly what I did. Mine were all in one folder, so I was able to just use *.*. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Unlike MS-DOS you don't have to use *.* as a wildcard. * will sufice in Bash. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Not if there are files with no dot in their name that you _don't_ want to process. Randall Schulz -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Indeed. His point, though, was that the dot is simply a valid filename character in Unix/Linux, and doesn't have the special meaning that DOS/Windows applies to it. I knew that, but my workdays are all spent with Windows, and old habits are hard to break. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Man to the rescue... -==--==--==--==--==--==--==--==--==--==--==--==--==--==--==- nocaseglob If set, bash matches filenames in a case-insensitive fashion when performing pathname expansion (see Pathname Expansion above). -==--==--==--==--==--==--==--==--==--==--==--==--==--==--==- Note, too, that the pattern matching done to find file names using the asterisk / * and question-mark / ? wildcards is _not_ based on regular expressions in the conventional sense. It's referred to (for historical reasons) as "globbing." BASH does have regular expression matching in some of its primitives, but no for file-name-driven wild-card expansion.

I used a variation of this, but ended up with images sized to 416x234, when I had specified 480x234. Obviously, convert preserved the aspect ratio of the original images, fitting them to a height of 234. Does anyone know if there's an option to force the specified size? I would expect a little to be trimmed from the top and bottom, of course, which would be acceptable for this application (digital picture frame). That would be preferable to black bands on both sides of the images. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I suppose you have to specify options to trim. Read the man page, there are lots of options. Perhaps chop, clip, extract, resize, scale, trim... You will have to experiment, I don't know which one will be the correct one. - -- Cheers, Carlos E.

I guess you do not want to use a program with a GUI. My approach is here is pretty simple/ Digikam Edit/Select all /Batch/resize images and there you can get proportional, non proportional etc. Another program that does it and one that has the most filter for any possible format you may want to convert is xnview. Unfortunately the present version 1.70 does not work with compiz. The author is working in a new one and he already has the windows version upgraded. The windows version works under crossover. xnview 1.7 is an X application and it does things others do not. It was my favorite until I became a compiz use. Still I have it just in case. -=terry=- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

When I tried that with the version of digiKam that was installed with SUSE 11.1, the Batch menu had one item in it, an empty space. So I searched for digiKam in the software module of YaST, and found that there was a digikam-kde4 in addition to the one that was installed by default. I installed that, and in the new version (which appears to be a beta), the Batch menu has only "Convert DNG" and "Batch Convert Raw" in it. Where did you get a version that offers resize in the batch menu? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Reinstall the KDE3 version. Also make sure the packages digikamplugins and kipi-plugins are installed. Charles -- There are no threads in a.b.p.erotica, so there's no gain in using a threaded news reader. (Unknown source)

I was using my business computer with opensuse 11 and that's the one I have been using but before this reply I went to the machine with opensuse 11.1 and not only is all the same but I tested and it works. Charles answered you the problem you have. You do not have the plugins.
