If I batch resize a series of jpg's in gwenview or similar engine, the top bit of it appears of at the bottom. Has anyone encountered similar effects? Could anyone reproduce downloading Nikon D 50 images and then resizing to a similar effect?

Well, I'd like to help you out but I can't get Gwenview past the point of wanting a writable path for my files... Even though I specified one in the settings.

I've never used gwenview but use convert from Imagmagik instead. I use a D70 and have never seen the problem you claim.

Try: convert -geometry 640x480 -quality 75 input.jpg output.jpg

and see how that works.

I use the following all on one line: for I in `ls -1 *.JPG`;do convert -resize 640x480 ${I} ${I};echo ${I};done It does overwrite the originals but I only work on copies anyway. -- Ken Schneider UNIX since 1989, linux since 1994, SuSE since 1998 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I didn't know that gwenview could do batch processing and so was most pleasantly surprise to read this thread. But I have to admit that I am doing something very terribly wrong because I just, as a test, batch resized about a dozen images and they all came out perfect with not a distortion to be seen.

As Bruce said, I find ImageMagick much better for batch work. Try the command line he gave.

ps: works fine for my D70 and D200.

BTW, I did finally get gwenview to do the batchy resize and the resulting JPG files had absolutely nothing for a picture! Totally white. I would not use that program. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
