image - Android: Streched Bitmap after Matrix Rotation -


im trying rotate jpeg data array converting bitmap , rotating matrix. working fine problem appear when im trying rotate 16:9 image(with 4:3 think happen too, can appreciate well). cause matrix rotate image dont resize it, bitmap looking streched width or height depending of orientation im sending dataarray.

  protected bitmap doinbackground(void... params) {          // decode image in background.          bitmap bitmap = camerautil.downsample(mdata, mdownsamplefactor);         matrix m = new matrix();         log.i(tag, "bitmap=" + bitmap.getwidth() + "x" + bitmap.getheight());         if ((morientation != 0 || mmirror) && (bitmap != null)) {                            if (mmirror) {              m.setscale(1f, -1f);         }              m.postrotate(morientation);             return bitmap.createbitmap(bitmap,0,0,bitmap.getwidth(),bitmap.getheight(),m,false);         }          return bitmap;      }   public static bitmap downsample(final byte[] data, int downsamplefactor) {         final bitmapfactory.options opts = new bitmapfactory.options();         // downsample image         opts.insamplesize = downsamplefactor;      return  bitmapfactory.decodebytearray(data, 0, data.length, opts); }

i tried resize image manually, convert array nv21 image , rotate array convert later bitmap , send it. giving me problems(so slow , totally green , pink(raimbows!)). tryed use pre,set , postrotate too, didnt give me differente between tests made.

thx in advance!

i found way fix it. problem inside crop method, use static measures create bitmap, change method addapt depending of aspect ratio.

 if (bmp.getwidth() != radius || bmp.getheight() != radius) {             //depending of height , width aspect ratio scale image before crop             if (bmp.getheight() > bmp.getwidth()) {                 maspectratio = (float) bmp.getheight() / (float) bmp.getwidth();                 sbmp = bitmap.createscaledbitmap(bmp, radius, (int) (radius * maspectratio), false);             } else {                 maspectratio = (float) bmp.getwidth() / (float) bmp.getheight();                 sbmp = bitmap.createscaledbitmap(bmp, (int) (radius * maspectratio), radius, false);              }         }     } else {         sbmp = bmp;     }     //output bitmap have final scale of thumbnail, radius x radius     bitmap output = bitmap.createbitmap(radius,radius, config.argb_8888);     canvas canvas = new canvas(output); //.....draw canvas, etc etc

caching - How to check if a url path exists in the service worker cache -

i need check if particular url path exists in service worker cache. example, suppose url is: /myserviceworker/service?a=110&b=70 this url exists in cache, there many of them different values of , b. now, suppose want refresh of these urls, how can that? i want know how access key values service worker cache. if know key, plan follows: var url = new url(key); if(url.pathname === "\/myserviceworker/service") refetch key but not sure how cache key , in format is. mean, string or url? cache api has match() method returns promise resolving in response object if match or undefined if no match exists. second parameter object can specify ignoresearch not take account url parameters. the ignoresearch option supported firefox ( chrome status here ). in other hand, retrieve cache entries, can use keys() method.
