Subject: @GetImageSize now returns additional index 'MimeType' and new function
X-Git-Tag: php-4.3.0dev_zend2_alpha2~150
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=c8f1529d08976be948356622a2b27cddee023d51;p=php

@GetImageSize now returns additional index 'MimeType' and new function
@imagetype2mimetype to convert php imagetypes to mime-types. (Marcus)
#the reason why i export php_imagetype2mimetype is that i use that for
#exif, too. Followup example will explain why.
