error "Impossible de convertir \" 651.968017578125\" en type real." number -1700 from " 651.968017578125" to real

What I really meant to provide:

Consider changing clear text 29 to (29 as number) in:

set pHeight to iFIELD / (29 as number)

else if iTAG contains "kMDItemPageWidth" then

set pWidth to iFIELD / (29 as number)

Use the following in the Python trimit function:

print(\"{:.2f} x {:.2f}\".format(r.size.width / 29L, r.size.height / 29L))

and your trimbox dimensions will be returned as ww.ww x hh.hh.

If you want to round your AppleScript variables to n places, add another function:

on roundit(n, decimals)

set x to 10 ^ decimals

set y to (((n * x) + 0.5) div 1) / x

return y as number

end roundit

and your process_PDF function now uses:

do shell script "echo " & fileName & space & nPages & space & my roundit(pWidth, 2) & " x " & my roundit(pHeight, 2) & space & my trimbox_(quoted form of POSIX path of f) & return & " >> $HOME/Desktop/List.txt"

And for a one-page, Letter PDF:

p51.pdf 1 21.10 x 27.31 21.10 x 27.31

Also, in your process_PDF function, the following will avoid considerable text string manipulation in If/else:

set t to paragraphs of (do shell script "mdls -name kMDItemFSName -name kMDItemNumberOfPages -name kMDItemPageHeight -name kMDItemPageWidth " & x & " | awk '{print $3}'")

set {fname, nPages, pHeight, pWidth} to t

logfname

"p51.pdf"

lognPages

1

logpHeight

792

logpWidth

612

Use this:

print(\"{:.2f} x {:.2f}\".format(r.size.width / 29L, r.size.height / 29L))

and your trimbox dimensions will be returned as ww.ww x hh.hh.
