i'm searching jquery plugin image area selection. need extract x, y rectangle , save coordinates in database. i have working case already, question if plugin supports both crop/area selection , zooming/panning. i've been through plugins on page http://techslides.com/image-zoom-drag-and-crop-with-html5 , none of plugins support both. it's image of 1000x1000 perfect if zoom in , make selection, zoom out while still having aspect ratio of image/zoom setting. i hope can me in right direction. if doesn't exist, i'm going develop , make public others use :-) best regards jens

i have seen prefix n in insert t-sql queries. many people have used n before inserting value in table. i searched, not able understand purpose of including n before inserting strings table. insert personnel.employees values(n'29730', n'philippe', n'horsford', 20.05, 1), it's declaring string nvarchar data type, rather varchar you may have seen transact-sql code passes strings around using n prefix. denotes subsequent string in unicode (the n stands national language character set). means passing nchar, nvarchar or ntext value, opposed char, varchar or text. to quote from microsoft : prefix unicode character string constants letter n. without n prefix, string converted default code page of database. this default code page may not recognize characters . if want know difference between these 2 data types, see post: what difference between varchar , nvarchar?
