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.
