Photo: Batch resize in half (x 0.5)

[OdFori]

Hi,

I see that in Batch jobs you can resize by typing in only a width or only a height, and it will keep the aspect ratio, which is nice.
I was wondering if it's also somehow possible to make all images half the size, regardless of the resolution or the aspect ratio of the images.

Thanks for the help

There is an A for Aspect Ratio which needs to be checked after you enter the same 'size' into the W and H fields.

You but that makes the images still fit in the same max width/height. What I meant is that it will be In half, even for potentially vastly different scales:

100 * 50           =  50 * 25

15000 * 100    =  17500 * 50 

4 * 4                  =  2 * 2

Sorry if that was a bit unclear. Would such a thing be possble?

Try setting the W field to w*.5, or the H field to h*.5

Scaling by a percentage of the original image does not seem to work.

But you can include macros in a batch job. Maybe that could be a workaround.

Both "w*.5" and "h*.5" work for me.

A macro would not be a workaround. They can only set specific widths or heights, and only by using a complex method involving Filters > Distort > Equations....

Gave it another try ...

wPOINT5 works ... if you use wCOMMA5 it does not.

Interesting. I wonder if that's true in general for field expressions, or if it's a bug in the New Batch Job dialog? (And if it's been reported?)

Thanks, works wonderfully.
