Hello, i need some image convertor (allowing quick batch convert of images), BUT with support for 16 bit and 32 bit images files (like 32 bit exr and 16 bit tif for example). I had a look at Link(s): http://www.xnview.com/ which looks cool and has a nice quick GUI, but im not able to keep the image "depth" (32 or 16 bit),…
Also you could take a look at ImageMagick. It's a command-line tool, like what chronic suggested above, so it's very useful for automating things. Worth a look, I've used it for many things, it's great.
The best converter I have seen so far is ImageConverterPlus. Im not sure about the LZW compression, but it can do a lot and it is very fast. We used it in our previous company for .TGA files, but it can handle a lot of file extensions.
