NConvert copy/noop operation?

Post by Miriam »

With this command,
nconvert -q 100 -rotate 0.0 -o that.jpg this.jpg
the output will be larger than the input.

Is it possible to specify a copy operation to make the output identical to the input, except for the file creation time?

Very bad idea :( Bloats size, quality loss (minimal), no benefit ...

Lower "q" could approach original size, but would trash quality ... :(

Probably no, but would be easy to add of you convince Pierre/Xnview about benefits of such a feature ;)
There is indeed no WinZIP under my rock.

For example, a file which comes out of a digital camera, is often rotated, cropped, and otherwise post-processed in a number of ways. I'm considering how to automate (most of) this processing by entering NConvert command-line strings in an image database. For this purpose, I want a copy/noop option in NConvert.


Of course, I'd be very happy if I could somehow teach XnView to record how I'm processing an image file, and then have XnView emit an NConvert command to do the same thing... but that would be asking a lot, wouldn't it?
