As an extension to my last question, I just discovered the image processor script in CS6 to batch resize images. Seems simple enough - I apply to a folder with these settings:

enter image description here

And yet the output for the few screenshots I have saved in that folder is all over the place!!

enter image description here

Not only are all these images (and they're definitely the right ones - taken from the new output folder that was created) different sizes from that specified in the script dialog, but the third, colourful one, scales as I increase the size of the preview window, whereas the others don't.

This seemed like such a simple thing to do, but apparently I can't manage it... :/

Can anyone please say what I'm doing wrong?

  • scaling within the OS preview window is completely unrelated to this and should be ignored.

This is a terminology issue.

Resize to Fit = Shrink to the first maximum reach of the following W and H sizes.

So if your image is very tall you'll hit the H limit first, and the aspect ratio won't be changed so the H limit will be exactly as you specified but the W much less than your limit.

And Vice-Versa.

As to the Preview scaling as you resize the window, that's probably because you have Preview's View set to Zoom to Fit.

    Command + 0 [in Preview] will give you "show me the actual size of this image" and is probably the best shortcut in all of Mac OS X. Certainly one I use more often than just about anything other than Command + Spacebar to launch Spotlight to use as a launcher.

  • "resize to fit" also means scale UP to fit, not just shrink.

  • It should never be used for scaling up.

  • That may be true, but it does do it.

  • Thank you guys. So if I'm trying to simply get images to fit a certain pixel size (W & H), regardless of how they start out, what's the way to do this? May 30, 2014 at 14:42
