P: Unable to use math to resize Save for Web

[dave_allen1]

You have a high res image, made from a new document preset with dimensions set at a certain ratio of the (known) final web image, say x3. You used to be able to Save For Web and then in the Image Size field perform math: eg. XXXpx/3. Thus giving you the final web image size. Math calculation no longer seems to work in Mac CS5.1

Hmm. I don't remember this being a feature in Photoshop. What version do you have where it works?

Looks like that last worked in Photoshop CS3. I do notice that the interface has changed a bit since then:

CS3:


CS4:


It looks like the issue is that the new dialog has code suppressing the ability to enter mathematical symbols. Not sure if this was done on purpose. I'll let the engineers know.

Cool. Thanks Brett.

Any developments?
