java - Applying blur using RenderScript in Android creates weird output -

-

i'm attempting apply blur image using renderscript class. here code use (where this.image original bitmap)

    bitmap inputimage = this.image;     int height = inputimage.getheight();     int width = inputimage.getwidth();     bitmap blurredimage = bitmap.createbitmap(width, height, bitmap.config.argb_8888);      renderscript rs = renderscript.create(context);     scriptintrinsicblur theintrinsic = scriptintrinsicblur.create(rs, element.u8_4(rs));     allocation tmpin = allocation.createfrombitmap(rs, inputimage);     allocation tmpout = allocation.createfrombitmap(rs, blurredimage);     theintrinsic.setradius(25.f);     theintrinsic.setinput(tmpin);     theintrinsic.foreach(tmpout);     tmpout.copyto(blurredimage);      this.image = blurredimage;     return true;

this input , output function http://imgur.com/a/ewjv6

for reason, appears double image , keep green channel or something. fidling around blur radius doesn't work, , can't find wrong code (which copied working example)

i had same error , found out causing it, know it's question 2 years ago still ones come same problem.

the problem images i've been using rgb_565 formatted , because renderscript blurring not getting enough specifications rgb_565 images results outputs this.

i using universalimageloader rgb_565 configuration reduce memory usage , having blur effect when necessary on downloaded images, , when remove configuration use default argb_8888 format, fine!

sum up: don't use rgb_565 while having renderscript blur, use argb_8888 instead.

php - render data via PDO::FETCH_FUNC vs loop -

i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
