Cool.

By the way, if you want to cut out the "middle man", and just have ImageMagick do the resizing, you can use:

convert input.pdf -resize 600x800! output.pdf

The units for -resize are pixels, 1/72th of an inch. It'll do every page. The exclamation mark is needed if you want to lose the aspect ratio.

Very handy if put in a batch file to do an entire directory (or more) at once. Let me know if you'd need help with that. (I'd need to know your operating system.)

Have you tried AnyBizSoft PDF to Word converter. It says it supports Thai and presumably once it's in Word you could tidy it up (assuming Word supports Thai) - and it's free! You can check it out here

EDIT: Just tried it with a vectored PDF and what it gives you is an image of each page in Word, so whilst you cannot edit the text you can resize the image - which might give you what you want.

Wow! very handy command.

I've tried the command with my pdf file, it failed on the way. I believe it was because my original file has a number of different page sizes.

It worked if my pdf input file has consistent page size; or same page size for all pages.

Thanks again.

Thanks for your suggestion, OCR for Thai language has progressed no where near acceptable; so I would totally ignore this technology.

Even converting a vectored pdf into Word for Thai text, the result is still not acceptable, too many errors to correct.

If I have a vectored PDF which page size is too big with too much text, I use sopdf to trim the margins, and if necessary, to split each page into two, and view it in landscape mode. I can live with this approach.
