批量处理自动生成 HD 文件。
借助 ImageMagick，可以实现自动批处理生成 -HD 图片。
*****************************************************
DOS下，分两个BAT文件。使用时，把这两个文件放在一个文件夹A中，然后，把要命名的png图片全部放在独立的一个文件夹B中，B文件夹也放在A文件夹下。然后使用 scale.bat B，即会生成B-HD文件夹，里面是处理后的图片。
====================
文件scale.bat
====================
if ""=="%1" goto MYEND
cd %1
set aaaa=%CD%
cd ..
del /Q "%aaaa%-hd"
rmdir "%aaaa%-hd"
xcopy /S /E /I "%aaaa%" "%aaaa%-hd"
cd %aaaa%-hd
for /r %%i in (*.png) do call ..\scale_step2.bat %%~ni
cd ..
:MYEND
===============
文件scale_step2.bat
===============
rename %1.png %1-hd.png
convert -scale 50%% %1-hd.png %1.png
mogrify -strip %1-hd.png
*****************************************************
mac机下，把ImageMagick文件放到~/目录下。分两个.sh文件。使用方法同DOS下
=====================
scale.sh
=====================
if [ "" = "$1" ]; then
echo 'usage: ./scale.sh dirname'
exit 1
fi
if [-d $1]; then
el
echo 'usage: ./scale.sh dirname'
exit 1
fi
cd $1
aaaa=$(pwd)
echo $aaaa
cd ..
rm -r $aaaa-hd
cp -r $aaaa $aaaa-hd
cd $aaaa-hd
export MAGICK_HOME="$HOME/ImageMagick-6.7.5"
export PATH="$MAGICK_HOME/bin:$PATH"
export DYLD_LIBRARY_PATH="$MAGICK_HOME/lib/"
chmod 777 ../rename.sh
clear
echo cd $aaaa-hd
echo
../rename.sh %.png %-hd.png
for img in *-hd.png
do
convert -scale 50% $img $img.png
mogrify -strip $img
done
echo
../rename.sh %-hd.png.png %.png
