Request: Ability to skip existing files (or delete files as going along)

[rbairwell]

I've a collection of around 6,000 images I need to clip (yes, for haar classifier training) and I obviously don't want to do this in one go. I've started imageclipper (on Linux) and done a few files and then needed a break: however, I can't easily find where I was (as imageclipper doesn't "pre-sort" the files).

Could you add an option to skip "pre-clipped" files (i.e. if the output filename -0 ignoring the %x/%y/%w/%h etc settings already exist), add a "checkpoint" option (recording which files have already been seen) or an option to delete the original files as you progress through them (maybe a warning in this case).

Thanks for an otherwise excellent tool.

Actually I ran into this myself (I'm not the original author). What I did to fix this was quite rudimentary, I simply added support for using the --frame N argument that previously only worked for video frames, to also apply to what image to start on.

So when using imageclipper it will show you in the console window what "frame" it is at. So if you restart the program and specify the same list of input files, you can skip to the one you were at last time using --frame.

Not a very advanced solution, but at least something! I will see if I get around doing something more advanced in the future. Otherwise if you're willing to add the feature yourself, please fork the repo and create a pull request.
