Step 3 input command lines to edit pdf page content size

  1. edit page size---pdftools -i "C:\input.pdf" -o "C:\output.pdf" -x "llx lly urx ury"

where the parameter "llx lly urx ury" is a form of rectangles, which is described in remark one

2.  edit page content---pdftools -i "C:\input.pdf" -o "C:\output.pdf" -j "60% 70% true"

where the first parameter means to set page content to 60% of the page width and the second parameter to 70% of the page height, and the third parameter is a Boolean type value to set whether to center on page. 

Remark One: Rectangle Description
Rectangles are used to describe locations on a page and bounding boxes for a variety of objects, such as fonts. A rectangle is written as an array of four numbers giving the coordinates of a pair of diagonally opposite corners. Typically, the array takes the form [llx lly urx ury] specifying the lower-left x, lower-left y, upper-right x, and upper-right y coordinates of the rectangle, in that order. The other two corners of the rectangle are
then assumed to have coordinates (llx, ury) and (urx, lly).

Remark Two:
Usually there are three size unit such as point (pt), inch (in), millimeter (mm). Point size can be converted to inch like point/72=inch, and point to millimeter like point/72*25.4=millimeter. For example, the 595.5pt can be 8.27in or 210.06mm by calculating as:

595.5/72=8.27
595.5/72*25.4=210.06
Remark Three: if urx (Width) or ury (Height) equal zero, the value of urx (Width) or ury (Height)  will be calculated automatically, maintain their original aspect ratio,
eg.
pdftools.exe -i C:\in.pdf -o C:\out.pdf -x "0 0 612 792" -j "612 792 true"
pdftools.exe -i C:\in.pdf -o C:\out.pdf -x "0 0 612 0" -j "612 0 true"       //ury (Height) will be calculated automatically
pdftools.exe -i C:\in.pdf -o C:\out.pdf -x "0 0 0 792" -j "0 792 true"       //urx (Width) will be calculated automatically

so combine them , they can be written as follow

pdftools -i "C:\input.pdf" -o "C:\output.pdf" -x "0 0 595.5 842.25"  -j "595.5 842.25 true"    

once you finish your input, press “enter” key, and you will see
