#19210 [NEW]: read_exif_data truncates JPEG comments to 198 characters

From: roland@astrofoto.org Operating system: RedHat 7.2/Linux 2.4.9 PHP version: 4.1.2 PHP Bug Type: *Graphics related Bug description: read_exif_data truncates JPEG comments to 198 characters I have a JPEG (*not* from a digital camera) to which I have added a comment block using wrjpegcom. rdjepgcom confirms that the comment is correct in the file. The length of the comment is about 345 characters. When I read the comment back from PHP using read_exif_data, the length is truncated at 198 characters. Note that JPEG comment blocks can be up to 64k(!). The comment in question is all text, no ASCII nulls, so I'm assuming this truncation is happening inside PHP. -- Edit bug report at http://bugs.php.net/?id=19210&edit=1 -- Try a CVS snapshot: http://bugs.php.net/fix.php?id=19210&r=trysnapshot Fixed in CVS: http://bugs.php.net/fix.php?id=19210&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=19210&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=19210&r=needtrace Try newer version: http://bugs.php.net/fix.php?id=19210&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=19210&r=support Expected behavior: http://bugs.php.net/fix.php?id=19210&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=19210&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=19210&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=19210&r=globals
