FPDF - failing to open eps file?

I am unable to use EPS file in FPDF (but here it is able to open EPS http://www.fpdf.org/en/script/script84.php ). What is wrong in my code?

Error:

Fatal error: Uncaught Exception: FPDF error: File was saved with wrong Illustrator version: nato.eps in eps/fpdf/fpdf.php:271 Stack trace: #0 eps/fpdf_eps.php(42): FPDF->Error('File was saved ...') #1 eps/test.php(7): PDF_EPS->ImageEps('test.eps', 30, 20, 150, 0, 1) #2 {main} thrown in eps/fpdf/fpdf.php on line 271

$pdf->Output();

I believe the problem is that you are confusing a script which specifically deals with EPS files created by Adobe Illustrator version 9, with a scritp which can handle general EPS files.

EPS stands for Encapsulated PostScript, PostScript is a programming language. So what is in an EPS file is a PostScript program.

Now machine generated PostScript, such as that produced by Adobe Illustrator, is of course always the same general format and its possible (as here) to write some code which can deal with its content in a limited fashion. However, the program generated by a different application will be different, possibly very different.

The only way to be able to read a general EPS (or PostScript file) is to use a full PostScript interpreter such as Ghostscript.

The script you have above is capable of reading some of the marking content of an EPS generated by a specific version of Adobe Illustrator and rendering a PDF file from it, it is not a general PostScript interpreter and so is not capable of interpreting arbitrary EPS files. The author says as much in the page you linked to in your question.

Only vector drawing is supported, not text or bitmap

Now notice that the exception is right at the beginning of the script where it checks the %%Creatorcomment to see if its the correct version of Illustrator. That's where it fails for you, undoubtedly because your EPS (which you haven't shared) doesn't include the correct comment.

In short you can't use this script to interpret general PostScript or EPS programs. If you want to do that you need something like Ghostscript or Adobe Acrobat Distiller.
