Re: [Sheflug] Batch Process Images - Debian

Hi

Oh... right.... thanks for everyone's help :)  Here we go... 'man 
imagemagick'.  I'd forgotten about that.  Too much use of KDE and 
Gnome...

Hmm... looks useful :)

Yes, but the pro cameras tend to have 3 to 10Mb files for the 35 m/m 
SLR replacement and the digital Rollei medium format camera is about 
10Mb to 30Mb in size.  Hence the need for image processing when 
uploading to a web page.  In my case 3008x2000 pixels is small.

You can do this with Photoshop in Mac or winduhs but to be honest I 
prefer the Linux desktop and think that ImageMagick is better anyway.  
Oh....  mogrify... might work !
