It may be time to revisit the capabilities of ImageMagick since the
original perl script was written. At that time there were licensing
issues with GIF so they could not be included in IM. A perl script may
have been necessary at that time. IM can however, size, crop, change
format in a half line command instead of an eloborate perl placement.
ImageMagick®, is a software suite to create, edit, and compose
bitmap images. It can read, convert and write images in a variety of
formats (about 100)
including GIF, JPEG, JPEG-2000, PNG, PDF, PhotoCD, TIFF, and
DPX. Use ImageMagick to translate, flip, mirror, rotate, scale, shear
and transform images,
adjust image colors, apply various special effects, or draw
text, lines, polygons, ellipses and B\['e]zier curves.
stream
is a lightweight tool to stream one or more pixel
components of the image or portion of the image to your choice of
storage formats. It writes the
pixel components as they are read from the input
image a row at a time making stream desirable when working with large
images or when you require
raw pixel components.
# !/bin/sh -
for i in *.jpg; do
j=`basename $i | sed -e 's/\.jpg//'`
mogrify -resize 800x600 -format png *.jpg
done
Happy gif-ng!

>> I?m serving the mpegs from Apache and viewing with a browser plug in (QuickTime). They now appear ?sticky? and ?jerky.? Older mpegs, created with the previous system, playback fine so the problem is not with Apache, browser, or plug-in. Newly created files are also much smaller (1.3M) compared to before (11M) , so I suspect the authors also chose a lower mpeg quality setting.
