android - How to get full size image from custom front camera with full screen length -


i making android app using front camera of device , has take picture in portrait form want save picture in same result showing in preview when take photo , save bitmap bitmap seems awkward increases size in length. seems doing wrong squeezing camera picture while saving.

i have searched many links , came know have set aspect ratio. did not it. want in coding because have complete app , working best on samsung grand , s4 not working on lg g3 , .

here doing surfaceview class . sharing surface view class know there wrong here , rest of other classes easy . camerapreview.java

public class camerapreview extends surfaceview implements surfaceholder.callback {  private camera camera; public static  surfaceholder holder; private activity activity;   public camerapreview(context context, attributeset attrs, activity activity) {     super(context, attrs);  }  public camerapreview(context context, attributeset attrs) {     super(context, attrs); }  public camerapreview(context context) {     super(context); }  public void init(camera camera,activity activity) {     this.camera = camera;     this.activity = activity;     initsurfaceholder(); }  @suppresswarnings("deprecation") // needed < 3.0 private void initsurfaceholder() {     holder = getholder();     holder.addcallback(this);     holder.settype(surfaceholder.surface_type_push_buffers);  }  @override public void surfacecreated(surfaceholder holder) {     initcamera(holder); }  private void initcamera(surfaceholder holder) {     try {         camera.parameters parameters = camera.getparameters();         list<camera.size> previewsizes = parameters.getsupportedpreviewsizes();         camera.size previewsize = previewsizes.get(0); //480h x 720w         for(int = 0 ; i<=6;i++){               log.v("preview sizes"+previewsizes.get(i));             camera.size previewsizedemo = previewsizes.get(i);             log.v("preview size are" +previewsizedemo.width+""+ previewsizedemo.height+"of"+i);             camera.size previewsizedemo1 = previewsizes.get(1);             log.v("preview size of 0 is" +previewsizedemo1.width+""+ previewsizedemo1.height);         }          parameters.setpreviewsize(previewsize.width,previewsize.height);       parameters.setzoom(camera.parameters.focus_distance_optimal_index);          camera.setparameters(parameters);         requestlayout();         camera.setpreviewdisplay(holder);         camera.startpreview();        } catch (exception e) {         log.d("error setting camera preview", e);     } }  @override public void surfacechanged(surfaceholder mholder, int format, int width, int height) {      camera.parameters parameters = camera.getparameters();     list<camera.size> previewsizes = parameters.getsupportedpreviewsizes();      camera.size previewsize = previewsizes.get(0); //480h x 720w      parameters.setpreviewsize(previewsize.width,previewsize.height);          requestlayout();      camera.setparameters(parameters);      display display = ((windowmanager)activity.getsystemservice(context.window_service)).getdefaultdisplay();     if(display.getrotation() == surface.rotation_0) {         camera.setdisplayorientation(90);         parameters.setpreviewsize(previewsize.width, previewsize.height);     } else if(display.getrotation() == surface.rotation_270) {         camera.setdisplayorientation(180);         parameters.setpreviewsize(previewsize.width, previewsize.height);     }      camera.startpreview();      }// end surfacechanged      @override public void surfacedestroyed(surfaceholder holder) {     log.e("tabact"+"surfacedestroyed()");     camera.stoppreview();     camera.setpreviewcallback(null);     camera.release();     camera = null;      this.getholder().removecallback(this);   }  private camera.size getoptimalpreviewsize(list<camera.size> sizes, int w, int h) {     final double aspect_tolerance = 0.1;     double targetratio=(double)h / w;      if (sizes == null) return null;      camera.size optimalsize = null;     double mindiff = double.max_value;      int targetheight = h;      (camera.size size : sizes) {         double ratio = (double) size.width / size.height;         if (math.abs(ratio - targetratio) > aspect_tolerance) continue;         if (math.abs(size.height - targetheight) < mindiff) {             optimalsize = size;             mindiff = math.abs(size.height - targetheight);         }     }      if (optimalsize == null) {         mindiff = double.max_value;         (camera.size size : sizes) {             if (math.abs(size.height - targetheight) < mindiff) {                 optimalsize = size;                 mindiff = math.abs(size.height - targetheight);             }         }     }     return optimalsize; }

keep in mind using front facing camera only. please me in how can take full length image front camera out getting inverted other angle portrait.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
