Applescript to resize/greyscale Kindle Screensaver Files

Hello all,

When I first got my Kindle, I spent some time looking for a very (very!) simple way to batch convert my existing jpg files to greyscale (colour renders poorly on the Kindle) images of the appropriate size for my Kindle 3.

There are many options, but none of which were suitably easy to use. However, I did find that any joe can create an Applescript to do this. It's ridiculously easy.

As it may save other readers the notional effort of creating their own script, I attach mine. It outputs to a file called "Kindled" on the desktop. You may need to create such. Simply drag and drop any file or folder with source jpgs on it.


Good luck

You, good sir, are a gentleman and a scholar. I'm working on a website for Kindle Screensavers and I feel as if this'll come in really handy.

Edit: Ah, spoke to soon.

Is imagemagick available for macosx? This is how I'd do it in linux:

$ convert -colorspace gray input.jpg output.jpg

and to resize as well:

$ convert -colorspace gray input.jpg -resize 800x600! output.jpg

I use this:

Code:
convert $FILE$ -colorspace Gray -resize 600x800> -gravity center -background Gray -extent 600x800 kindle_$NAME$.png
"!" --> aspect ratio KO

So what do you want to do? Add border trims to the image?

Yes, I prefer to maintain the aspect-ratio and fill the remaining space with gray
