Image number or name

Hope someone can help.

I wish to write data about an image to a file, so that I can review it later in post.

I intend to use print_screen and I’m using Lua.

But how do I uniquely link the data to the image just taken.

After all I will have, potentially, up to a 100 or so images in any given session.

As I say, I hope someone can help.

Cheers

Yes I was aware of that, but I don’t think it explicitly references the image file name. Or does it.

Any other thought I’ve had is to time stamp things.

BTW the Lua documentation seems to imply accessing os_time, but I can see a Lua call to do that.

Thanks for responding.

Cheers

'get_exp_count' corresponds to number in filename

Hint:
Code: [Select]
filename = string.format('IMG_%04d.JPG', get_exp_count())
