GIF animate too fast on Computer - iOS -

-

i trying create gif animated images, pass array of images.

lets have 4 seconds video , extract 120 frames it. regardless of created gif size, create gif 120 frames. problem is, when open gif in iphone (by attaching mailviewcomposer or imessage) runs fine, if email it, or import computer, runs fast. can suggest wrong here?

i using hjimagestogif gif creation. dictionary gif properties below:

nsdictionary *prep = [nsdictionary dictionarywithobject:[nsdictionary dictionarywithobject:[nsnumber numberwithfloat:0.03f]                                                                                     forkey:(nsstring *) kcgimagepropertygifdelaytime]                                                  forkey:(nsstring *) kcgimagepropertygifdictionary];  nsdictionary *fileproperties = @{                                  (__bridge id)kcgimagepropertygifdictionary: @{                                          (__bridge id)kcgimagepropertygifloopcount: @0, // 0 means loop forever                                          }                                  };

creation of gif:

cfurlref url = (__bridge cfurlref)[nsurl fileurlwithpath:path];  cgimagedestinationref dst = cgimagedestinationcreatewithurl(url, kuttypegif, [images count], nil); cgimagedestinationsetproperties(dst, (__bridge cfdictionaryref)fileproperties);  (int i=0;i<[images count];i++) {     //load animage array     uiimage * animage = [images objectatindex:i];      cgimagedestinationaddimage(dst, animage.cgimage,(__bridge cfdictionaryref)(prep));  }  bool filesave = cgimagedestinationfinalize(dst); cfrelease(dst); if(filesave) {     nslog(@"animated gif file created @ %@", path); }else{     nslog(@"error: no animated gif file created @ %@", path); }

to save gif, i’m using:

alassetslibrary *library = [[alassetslibrary alloc] init];  nsdata *data = [nsdata datawithcontentsofurl:[nsurl urlwithstring:temppath]]; data = [nsdata datawithcontentsoffile:temppath];  [library writeimagedatatosavedphotosalbum:data metadata:nil completionblock:^(nsurl *asseturl, nserror *error) {     if (error) {         nslog(@"error saving gif photo album: %@", error);     } else {         // todo: success handling         nslog(@"gif saved %@", asseturl);     } }];

thanks everyone.

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...
