Does anyone know how the deadpage coords.txt are made?

I'll first write up my findings. A line consist of three pairs of coordinates:

27 13 232 108 283 130

* The blue coordinates are from the topleft corner of the image-rectangle.
* The green coordinates are from the bottomright corner of the image-rectangle.
*The red coordinates are measured from the topleft corner of the image-rectangle and is used for the image-origin.

You can also see that some coordinates exceed the value 256 while the deadpage image file is only 256x256. I've found out that each coordinate should be divided by 1.3 to have the correct values for coordinates on the actual image.
Why is this done? Well, there are alot of dead bodies, too much in fact to have them placed in normal size. That's why CA resized the dead bodies and used these altered coordinates to avoid using different scaling values for in-game presentation (I know that was a bit difficult...)

Question:
But how do you alter the deadpage coords.txt and which image file should be edited, DEAD256.tga or DEAD256.LBM?
