I have a multi-page PDF file. Due to the nature of its making (scanning with a camera and then cropping), the pages are all in different (but similar) sizes. I would like to perform resizing on each of the pages, so that they become exactly the same size. By "resizing", I mean rescaling the width and height separately to fill the target page size (that is, not necessarily preserving the original aspect ratio).
The closest thing I can find is cpdf -scale-to-fit 150mm 200mm input.pdf -o output.pdf, but this command preserves the aspect ratio, resulting in undesired white padding space. Not exactly what I want.
Any idea how to achieve the effect?
