The ExtImage-Product works like the Zope Image-product, but stores the uploaded image externally in a repository-direcory. It creates a preview of the image (requires PIL). $Id: ExtImage.py 5740 2006-01-22 11:38:09Z roug $s$Release: 1.1.3 $i iþÿÿÿN(t*(sInitializeClasssDTMLFile(sDateTime(sIntTypes StringType(sjoinsisfile(sStringIOiiiit extImageAddtc CsV| ozt|dƒoj|i}|p|}|tti|dƒti|dƒti|dƒƒd}ti|t ƒ}n|i ƒ}t |||| ƒ}|i||ƒ|i|ƒi||d||| | ƒ|tjp |tjo,|i|ƒi||d||| | ƒn| d j o$d|} |i|| d| ƒSnd S( s Add a ExtImage to a folder tfilenamet/s\t:iis)The ExtImage %s was successfully created!tmanage_tabs_messageN(tidthasattrtfileRttitletmaxtstringtrfindt translatetTRANSMAPtselftthistExtImagetdescrtpermission_checkt tempExtImaget _setObjectt_getObtmanage_file_uploadt content_typet create_prevtmaxxtmaxytratiotUPLOAD_NORESIZEt UPLOAD_RESIZEtpreviewtREQUESTtNonetmessaget manage_main(RRR RR R RRRRRRR!R#R((t=/home2/kennisonb/webapps/zope/Zope/Products/Photo/ExtImage.pytmanage_addExtImageFs&      Rc BsÿtZeƒZeiddƒeiddƒeiddƒeiddƒeiddƒeid d ƒeid d ƒeid d ƒeid dƒeid dƒeid dƒeid dƒdZhdd<dd<dd„Z$dd?„Z%d@„Z&dA„Z'dB„Z(RS(CNsView management screenst manage_tabsR$tmanage_uploadFormsChange permissionst manage_accesssChange ExtFile/ExtImagetmanage_editExtFiles FTP accesstmanage_FTPstatt manage_FTPgettmanage_FTPlisttViewt index_htmlt icon_htmlticon_giftlinkRtdefaultitmini R içRicCs>tidƒ|||||ƒg|_d|_d|_ dS(s%initialize a new instance of ExtImaget__init__RiN( RtinheritedAttributeRRR RRt prev_filenametprev_content_typet has_preview(RRR RR((R%R5zs    cCs |iƒS(N(Rttag(R((R%t__str__‡sR:t0c Ks | d jot|dƒo |i} n|i| ƒp d}n|p|iƒ o,d|iƒ}|i |i ƒ\} } nL|o d|iƒ}d \} } n%|iƒ}|i |iƒ\} } |p| }|p| }|p|}|p|}|o'|d jott|ƒ|ƒ}n|o'|d jott|ƒ|ƒ}n|d jo|iƒ}nd|| |f}|od||f}n|od||f}nx6| iƒD](}| i|ƒ}d |||f}qÓWd |}|S( s= Generate an HTML IMG tag for this image, with customization. Arguments to self.tag() can be any valid attributes of an IMG tag. 'src' will always be an absolute pathname, to prevent redundant downloading of images. Defaults are applied intelligently for 'height', 'width', and 'alt'. If specified, the 'scale', 'xscale', and 'yscale' keyword arguments will be used to automatically adjust the output height and width values of the image tag.
