I just can't tell right now if I've been using a delinearized document or
not but I've learned that a delinearized one should be worked with.

First I tried to write the script because I was unaware how to integrate
with the app. After I failed I searched the web and found the patch for
multiple page metrics. Then I made the patch for multiple page tm
because my script failed.

Yeah, well, if there is only one page then I probably wouldn't use
the script (I have few documents that have a lot of pages). But
your advice is correct.

Well, you just made me realize that I've been struggling for a couple
of days and the solution was just a few keystrokes away. I've added
the f.save() and my script did it's job. The method 'save()' is not listed
among the methods of Pdf class and CObject is the only class Pdf is
inheriting so I didn't know I can call it. What did I miss?
Another thing I did not manage to run the script from command line,
ie transmit the pdf as a parameter. So if this is my current function,
how can it be called from outside with a file name parameter?
function zoom()
{
var f = loadPdf("/home/istirbu/test.pdf");
var pg = f.getFirstPage();
for(; f.hasNextPage(pg); pg = f.getNextPage(pg))
{
pg.setTransformMatrix([1.3,0,0,1.3,-90,-115]);
}
f.save();
f.unloadPdf();
}
Thanks,
Igor
