imagemagick problem

[zetjee]

Hello everybody.

I'd like to resize alot of images. (.jpg) to 3 other formats. To do this i use imagemagick.
Now i've got a little problem. The command i use is this:

for image in *.jpg
do
convert -geometry 500x400 $image 500x400/$image
convert -geometry 350x150 $image 350x150/$image
convert -geometry 80x50 $image 80x50/$image
echo $image
done

It scale good, but a image of 1280x1024 is scaled to 62x50! :S
Now i would like to fill the rest of the image with white. Is this possible? And how would the command be?

My last question: how to use the watermark option?

Thanks in advance

Take a look at this page. It discusses adding a white background to fill space and adding a watermark. It may get you started.
