-Short script :

<?php
  $taille = getimagesize("JPEG2000.jp2");
  dump $taille;
?>

-List of modules :
I dowloaded PHP4.3 binary for Windows (ZIP file), from your site.

-Any other information :
I tried the same script with a JPG image, it works.
I saw every where that JPEG2000 is managed in PHP 4.3. : http://www.zend.com/manual/function.getimagesize.php for exemple. Is there a "Zend" PHP or is it for the future ?

It's only working correctly in PHP > 4.3 -> doc problem.

Sadly, JPEG 2000 support didn't make it for 4.3. JPEG 2000 raw codestream support should be in 4.3.1. JP2 support will probably feature in 5.0.

A current stable snapshot should work for JPC, and JP2 will work if you compile from HEAD.

Thank you, i think the "bug" is closed. I am waiting for PHP 4.3.x where x > 1.

This remains open until jpc and jp2 are documented properly.  This may need to be faq that's referred to in various places?  Or maybe a language-snippet?  Because I doubt getimagesize() is the only appropriate place for this information.

Only thing to document is that since 4.3.1 PHP supports
JPEG 2000 and WBMP imagetypes too..

I have downloaded PHP 4.3.1 and i didn't found any change in using something like getimagesize("jpeg2000.jp2").
I have two questions :
Is there a remedy to read the header of a jpeg2000 and extract the length and height of the image ?
Is it possible to define a class and use it as a buffer to read the header of a jpeg2000 image ?

4.3.1 is identical to 4.3.0 except that one security change to CGI so the change hasn't happened yet.

This is now fixed/documented in CVS and will show up when the manual is next built, thanks for the report!
