chromeでスクショした地図画像をいい感じにリサイズして切り出したり変換したりした

image_convert.bash

dir=$(dirname $0)
if [ -e "$dir/converted_images" ] ; then
        echo "output directory exists"
else
        mkdir $dir/converted_images
fi

ls *.png | grep "_C" |
# head -n 2 |
while read line
do
        echo $line
        filename=$(echo $line | awk -F_ -v OFS="_" '{print $9,$10,$11,$12,$13}')
        baseFilename=$(basename $filename .csv.html.png)
        cp $line ${baseFilename}.png


        echo "basefilename: "$baseFilename

        # convert -trim -resize 500x200 ${baseFilename}.png ${baseFilename}.trim.500x200.png
