Convert images to thumbnails

README.md

Finds PNG images in the source folder, and saves corresponding thumbnails to the target folder.

Use with gistup to create gists (and blocks) from the command line. The directory containing your gist files gets initialized as a git repo. See this tutorial for a quick overview.

For additional tips on generating block thumbnails, see this HOWTO.

thumbnail.sh

#/bin/bash

pushd source

sources=(*.png)

for i in "${sources[@]}"; do
  echo "Converting $i"
  gm convert \
    -crop 1920x1000+312+510 \
    -resize 230x120 \
    "$i" \
    "../target/$i"
done
