AP 2 and export persona -> a lower resolution, how?

[jacekl]

I have a high-resolution image (9000x1000) that contains several independent elements that I want to export as separate files.
I use Export Persona, select these areas (slices) and I have a problem, because I need the resulting image to be at a lower resolution than the source, but I have a choice of 1x, 2x, 3x, etc.
How to make the resulting image with, for example, 1/3 of the source resolution?

You can type a width – e.g. 200w = width of 200 pixels – or a height – e.g. 500h = height of 500 pixels – into those fields instead of using the presets from the drop-down.

I would never have come across that 500w is 500 pixels wide.... is there documentation somewhere for these values?

Thanks Garry!

You’re welcome.

I don’t think it’s documented in the Help – if it is then I can’t find it. Someone had to tell me, otherwise I wouldn't have known.

An example of “100w” is given in the drop-down but there’s no obvious (to me) indication [A] that you can manually change it other than the drop-down button being a slightly different colour to the field to its left (with Dark UI, with Light UI there’s no difference in colour that I can see), or [B] what 100w means.
