I made a simple script today to convert my all my CR2 files into jpg 50%.
1.
you need Xnview (imagemagick dont like CR2)
http://download2.xnview.com/XnView-win-full.exe![]()
2.
Save this line into a batch file. MyConverter.bat
for %%Q in (*.cr2) do (
"C:\Program Files\XnView\nconvert.exe" -npcd 2 -size 256x256+0 -ctype grey -corder inter -out jpeg -o %%~nQ_Converted.jpg -ratio -rtype linear -rflag orient -resize 50%% 50%% "%%Q"
)
3.
save your file MyConverter.bat into your CR2 folder and double click on it
note. You can add your MyConverter.bat in the right click contextual menu in Windows Explorer so you dont have to copy this file in every folders
4.
wait and enjoy!!
