android - Change default camera properties -


i want take picture application using 

intent camera = new intent(mediastore.action_image_capture); startactivityforresult(camera, take_picture);

and send webserver. since webserver compresses 150x150 image of size not more 50 kb, don't need take 3264x2448 image of size ~ 2 mb because takes hell lot of time send transfer. want take minimum sized image.

so, there way ask camera specific sized image?

i tried using camera api , changing properties:

private camera mcamera;  camera.size picturesize = getsmallestpicturesize(mcamera                 .getparameters());         if (picturesize != null) {             mcamera.getparameters().setpicturesize(picturesize.width,                     picturesize.height);         }  private camera.size getsmallestpicturesize(camera.parameters parameters) {         camera.size result = null;          (camera.size size : parameters.getsupportedpicturesizes()) {             if (result == null) {                 result = size;             } else {                 int resultarea = result.width * result.height;                 int newarea = size.width * size.height;                  if (newarea < resultarea) {                     result = size;                 }             }         }          return (result); }

the problem still larger images. that's not actual problem:

when use preview this, this

enter image description here

not allowing user rotate preview, zoom in/out etc..

is there way use actual camera preview custom parameters?

some camera starting take image in landscape mode in portait mode. can fixed @ sdk level, bit expensieve @ runtime, cpu, can done.

you need smaller size:

-at sdk level implement pipeline, shrink captured image 10-15% of original one, drain battery, can done. - @ ndk level have implement custom driver each supported camera...for custom driver implement custom software , fine.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
