Scale image on dragging using famo.us -

-

i new famo.us, trying scale image on dragging.my code working fine 1 drag after not working. how can make work fro every drag? settransform make scale operation fixed?

define(function(require, exports, module) { var engine              = require("famous/core/engine"); var surface             = require("famous/core/surface"); var statemodifier       = require("famous/modifiers/statemodifier"); var draggable           = require("famous/modifiers/draggable"); var transform           = require("famous/core/transform"); var imagesurface        = require('famous/surfaces/imagesurface'); var maincontext = engine.createcontext(); var size_x = 200; var size_y = 200; var scale_x =1; var scale_y =1; var surface = new imagesurface({   size: [size_x, size_y],   content: 'img/1.jpg',   properties: {     backgroundcolor: 'rgba(200, 200, 200, 0.5)',     cursor: 'pointer'   } }); var draggable = new draggable({   xrange: [-100, 1000],   yrange: [-100, 1000] }); surface.pipe(draggable); var mod = new statemodifier({   transform: transform.translate(150, 100, 0) }); var mod1 = new statemodifier({  }); maincontext.add(mod).add(mod1).add(surface); draggable.on('update',function(data){   var delta = draggable.getposition();   var scale_x = (size_x+ delta[0])/size_x;   var scale_y = (size_y+ delta[1])/size_y;   mod1.settransform(   transform.scale(scale_x,scale_y, 0)   ); });  });

all need change how using scale function. scaling 'z' property 0. should 1.

so change this..

transform.scale(scale_x,scale_y, 0);

to this..

transform.scale(scale_x,scale_y, 1);

good luck!

C# random value from dictionary and tuple -

-
i have following code, , need random item contains string "region_1" dictionary. public static dictionary<int, tuple<string, int, currencytype>> itemarray = new dictionary<int, tuple<string, int, currencytype>>() { { 0xb3e, new tuple<string, int, currencytype>("region_1", 1500, currencytype.fame) } }; public static int generateitemid(string shopid) { var generateditem = itemarray.elementat(new random().next(0, itemarray.count)).key; } how select this? it's not possible efficiently... first create static random @ class level... prevent non-random behaviour if run query on short period of time... (it's seeded discrete clock) static random rnd = new random(); then: var item = itemarray.values .where(t => t.item1 == shopid) .orderby(_ => rnd.next()) .firstordefault()

cgi - How do I interpret URLs without extension as files rather than missing directories in nginx? -

-
so i'm trying install zoneminder , have run under nginx, has few compiled files need run using fast-cgi. these files lack extension. if file has extension, there no issue , nginx interprets file , return 404 if can't find it. if has no extension, assume it's directory , return 404 when can't find sort of index page. here have now: # security camera domain. server { listen 888; server_name mydomain.com; root /srv/http/zm; # enable php support. include php.conf; location / { index index.html index.htm index.php; } # enable cgi support. location ~ ^/cgi-bin/(.+)$ { alias /srv/cgi-bin/zm/; fastcgi_pass unix:/run/fcgiwrap.sock; fastcgi_param script_filename $document_root/$1; include fastcgi.conf; } } the idea is, under cgi-bin directory goes through fastcgi pipe. any idea on howi can fix this? upon closer inspection, realized zoneminder has 2 cgi sc...
