html - Prevent browser anti-aliasing when upscaling? -

-

with google's chart image api (which unfortunately deprecated april 2012), can generate qr codes.

qr code

i'm sure can change size of resulting image using api, i'd rather use css , width , height properties make little bigger.
in chrome @ least, results in nasty anti-aliasing (not preferable, since needs parsable machines). there way tell browsers not anti-alias upscaled images?

this guy has solution: http://nullsleep.tumblr.com/post/16417178705/how-to-disable-image-smoothing-in-modern-web-browsers

img {      image-rendering: optimizespeed;             /* fuck smoothing, give me speed  */     image-rendering: -moz-crisp-edges;          /* firefox                        */     image-rendering: -o-crisp-edges;            /* opera                          */     image-rendering: -webkit-optimize-contrast; /* chrome (and safari) */     image-rendering: optimize-contrast;         /* css3 proposed                  */     -ms-interpolation-mode: nearest-neighbor;   /* ie8+                           */   }

sooo you:

imgqr {      width:100px;     height:100px;     image-rendering: optimizespeed;             /* fuck smoothing, give me speed  */     image-rendering: -moz-crisp-edges;          /* firefox                        */     image-rendering: -o-crisp-edges;            /* opera                          */     image-rendering: -webkit-optimize-contrast; /* chrome (and safari) */     image-rendering: optimize-contrast;         /* css3 proposed                  */     -ms-interpolation-mode: nearest-neighbor;   /* ie8+                           */   }

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
