Photoshop CC 2015: Image Processor randomly adjusts image size ratio

I have to process several hundred images from PDF into JPEG. In order to do this I am using the Image Processor.

Getting the A5 and A6 size images to come out with the proper ratio between height and width wasn't a problem at all. I just specified it to make all images 100% x 100% of the original image.

Getting the "Carre M" and "Folded Carre M" images to come out in the proper size has been nothing short of frustrating.

For some reason, regardless of my settings, the image processor will force all images into a A-size ratio. So a source image for Carre M which is 14.85cm square is squashed into an A6 format making the image 14.85cm x 10.5cm. This skews the image to the point where it becomes useless.

Eventually I have managed to force the Carre M formats by specifying pixel sizes, so I did in the end get a 800x800 pixel 72dpi JPEG.

The "Folded Carre M" formats are basically two squares next to each other. making the image twice as wide as it is high.
However no matter what I do, even if I specify that I want an image to come out with 1600x800 pixels, Photoshop will force the image into a 1.4:1 ratio from 2:1.

I have bicubic resampling enabled, I have tried to allow the image to be enlarged, disallow enlarging, basically every single setting in the image processor and it flat out refuses to produce a 2:1 ratio image.

The source images are 3638x1819 pixels, setting the image processor to 100%x100% will result in a 2551x1819 pixel image. Setting it to make a 2551x1275 pixel image will make a 2551x1819 pixel image. Setting it to make a 3638x1819 pixel image, will make a, you've guessed it a 2551x1819 pixel image.
Scaling down for a thumbnail, that should be a 110x55 pixel image, results in a 78x55 pixel image.

Basically no matter what I do, Photoshop will force the image to have a 1.4:1 ratio, despite the explicit settings for a 2:1 ratio image.


I have tried every setting in PS of which I think that it might influence the outcome for the image processor. Up to and including the default paper settings for the printer. But nothing seems to work.

How do I fix this? Other than downloading GIMP and just ditching PS?

The image processor script does not change aspect ratio. It only constrains or enlarges the longest edge and keeps the aspect ratio the same. So if you want to actually change the aspect ratio of the image, you would have to make an action that resizes it to a 2:1, then apply that action in the image processor script (there's an actions dropdown there for that).

Like I said, I entered the exact size that the original images were. And even if I put in to scale to 100% or disabled the scaling, it would still change the aspect ratio of the images.

If Max's suggestion doesn't help, having a sample file and the Image Processor settings XML you're using that exhibits this behavior might help us debug.

I can't send a sample file, my boss will not allow that due to copyright, the XML settings file should be the default as is put in place by Adobe. Other workstations do the exact same thing.

Thanks for the responses. I have not managed to resolve the problem with PS. GIMP with the BIMP plugin made short work of it.

I was kind of hoping someone would have a "oh you need to set this or that" kind of answer, but that's okay. Having to dig through the settings XML and whatnot is way more effort than it's worth.
