    text
    copied!<p>I have an app that takes pictures of items, and these items must be viewable in a certain fixed region on the ActivityScreen. The problem is the picture displayed in the activity from the saved bitmap, looks nothing like what I previewed and photographed. It looks zoomed in and shows areas I did not even see in the preview when I took the picture: Here is the key code lines </p> <p><strong>IMAGE CAPTURE</strong>:</p> <pre><code>surfHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); captImageView = (ImageView)findViewById(R.id.CamImageView); byte [] photoData; Camera cam; SurfaceHolder surfHolder; SurfaceView surfView; Camera.PictureCallback cback; cback = new Camera.PictureCallback() { @Override public void onPictureTaken(byte[] data, Camera camera) { final int length = data.length; opts.inSampleSize = 4; final BitmapFactory.Options opts = new BitmapFactory.Options(); Bitmap bMap = null; try { bMap = BitmapFactory.decodeByteArray(data, 0, length, opts); } catch(Exception e) { }catch(OutOfMemoryError e) { } captImageView.setImageBitmap(bitmap); if(bMap==null) { cam.startPreview(); } else { savePhotoButton.setVisibility(ImageView.VISIBLE); takePhotoButton.setVisibility(ImageView.INVISIBLE); photoData = data; } } } </code></pre> <p><strong>IMAGE SAVE</strong>:</p> <pre><code>captImageView.setImageBitmap(null); // SAVE THE PICTURE THIS SAVES PICTURE IN WRONG SIZE. LOOKS LIKED ZOOMED IN NOT WHAT WAS PREVIEWED!!! public void photoSave(byte[] data) { final int length = data.length; final BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = 2; try { Bitmap bMap = BitmapFactory.decodeByteArray(data, 0, length, options); int quality = 75; File file = new File(getDir(), fname); fileOutputStream = new FileOutputStream(file); bMap.compress(CompressFormat.JPEG, quality, fileOutputStream); }catch(FileNotFoundException e) { } catch(OutOfMemoryError e) {} } </code></pre> <p>IMAGE DISPLAY as DRAWABLE in ACTIVITY DOES NOT WORK SHOWS IMAGE AS ZOOMED OR PORTIONS NOT SEEN IN PREVIEW AT ALL WHEN PICTURE WAS TAKEN!!</p> <pre><code>BitmapFactory.Options options = new BitmapFactory.Options(); options.inSampleSize = inSampSize; Bitmap bitmap = BitmapFactory.decodeFile(path, options); Drawable drawable = bitmap; ImageView pictureView = (ImageView)findViewById(R.id.pictureViewer); pictureView.setImageDrawable(drawable); </code></pre>
