Re: [LUG] Batch Converter

 

Hi Simon

Thanks for the reply. Yes to save space but also because thumbnails don't render very well under Ubuntu on a mounted drive. Not sure if I have the set up correct, but when I open a folder it takes ages to load and thumbnails appear very very slowly!

Trying to find a batch converter from raw into jpg. What do folks use

I don't but if I did I would probably script it using netpbm

netpbm package in Debian offers converters in many formats. 

You may have to go via PPM format e.g. rawtoppm file.raw | ppmtojpeg file.jpg

Of course the trouble with batch conversion to jpeg is jpeg is a lossy format, 
and you'll either end up with loss of quality or unnecessarily large files, for 
batch conversion from raw "-quality 95" disk space is cheap, images can't be 
recreated, unless you can spend the time deciding on good enough.

Why jpeg?
