batch resize in digikam


I'm trying to use batch resize on all the photos in an album to send to family members. Resizing individual photos with digikam is no problem.

When trying to use the batch resize everything came out black. Changing the background color to white resulted in a bunch of white boxes. No background doesn't seem to be an option.Batch resize goes through the motions but produces no useable output. The resize window offers a bunch of filter options, but they might as well be written in greek for all I understand of it.

Any idea what I may be doing wrong? Is this part of digikam just buggy?

You could do it from the command line, using ImageMagick's convert command. You might have to build a little script around it to resize all files in a batch operation.

The script below works, but is pretty stupid.

Code:
#!/bin/sh
# calls the "convert" program from "ImageMagick" suite and
# resizes all pictures in a given directory which comply
# to the file mask given.
#

DEBUG=""

if [ -z "$1" ]
then
  echo -e "Usage: resize_image <width>x<height>{+-}<x>{+-}<y>{%}{@}{!}{<}{>} quality file1 file2...\n"
  echo "The size and quality specification are equal to the -geometry specification"
  echo "in the \"convert\" command in the ImageMagick suite."
  echo "No spaces are allowed in the geometry specification."
  exit 1
fi

new_geo=$1
new_quality=$2
echo "1: $new_geo"
echo "2: $new_quality"
shift 2

number=0

for file in $*
do
echo $file
if [ -f $file ]
then
  let "number += 1"
  echo "processing file $number: $file"
  r_file=r_$file
  $DEBUG convert -geometry $new_geo -quality $new_quality $file $r_file
fi
done

echo "processed $number files"

No need to apologize for that script, it works a treat.
Thanks jlinkels.
