How can I resize to achieve 400px height for all pics?

[windozer]

Hello,

I'd like to know how I can batch convert images so that they all have 400px height after conversion, but with aspect ratio maintained. In XnConvert I can choose "Fit" as for the conversion mode, but strangely I still have to enter px values for both, height and width. I'd like to enter only height 400px and then have all pictures converted to pics with 400px height and the width should be adjusted in order to maintain the ratio.

My source files are all different, not from a camera. So I cannot simply use 'longest side' etc. As far as I understand, 'longest side' means that XnConvert looks what is the longest side of the image and then resizes this side and adjusts the other accordingly. But as I said, I want all images have 400px height, no matter what source dimensions.

how about you put in 9999999 for width, try it, and save your time typing that long story?

If you set 0 for width, and 400 for height?
