画像から顔を切り抜きたい。私はイメージビューを持っています。Androidで画像の切り抜きが機能しない
iv1 = (ImageView) MainActivity.this.findViewById(R.id.img1);
この画像ビューをクリックすると、ギャラリーから1つの画像が選択されます。コードは次のとおりです。
iv1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
imgNo = 1;
}
});
onActivityResultメソッドでは、選択した画像から切り抜くためのコードを追加しました。コードは次のとおりです。
@Override
protected void onActivityResult(int requestCode, int resultCode,
Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch (requestCode)
{
case SELECT_PHOTO:
if (resultCode == RESULT_OK && imgNo == 1)
{
selectedImage = imageReturnedIntent.getData();
try {
imageStream = getContentResolver().openInputStream(
selectedImage);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
yourSelectedImage = BitmapFactory.decodeStream(imageStream);
iv1.setImageBitmap(yourSelectedImage);
path1 = selectedImage.getPath();
bmpimg1 = yourSelectedImage;
viewHeight = iv1.getMeasuredHeight();
viewWidth = iv1.getMeasuredWidth();
try {
Paint paint = new Paint();
paint.setFilterBitmap(true);
Bitmap bitmapOrg =yourSelectedImage;
int targetWidth = bitmapOrg.getWidth();
int targetHeight = bitmapOrg.getHeight();
Bitmap targetBitmap = Bitmap.createBitmap(targetWidth,
targetHeight, Bitmap.Config.ARGB_8888);
RectF rectf = new RectF(0, 0, viewWidth, viewHeight);
Canvas canvas = new Canvas(targetBitmap);
Path path = new Path();
path.addRect(rectf, Path.Direction.CW);
canvas.clipPath(path);
canvas.drawBitmap(
bitmapOrg,
new Rect(0, 0, bitmapOrg.getWidth(), bitmapOrg
.getHeight()), new Rect(0, 0, targetWidth,
targetHeight), paint);
Matrix matrix = new Matrix();
matrix.postScale(1f, 1f);
BitmapFactory.Options bitmapFatoryOptions = new BitmapFactory.Options();
bitmapFatoryOptions.inPreferredConfig = Bitmap.Config.RGB_565;
bitmapOrg = yourSelectedImage;
myFace = new FaceDetector.Face[5];
myFaceDetect = new FaceDetector(targetWidth, targetHeight,
5);
int numberOfFaceDetected = myFaceDetect.findFaces(
bitmapOrg, myFace);
Bitmap resizedBitmap = null;
if (numberOfFaceDetected > 0) {
PointF myMidPoint = null;
android.media.FaceDetector.Face face = myFace[0];
myMidPoint = new PointF();
face.getMidPoint(myMidPoint);
myEyesDistance = face.eyesDistance() + 20;
if (myMidPoint.x + viewWidth > targetWidth) {
while (myMidPoint.x + viewWidth > targetWidth) {
myMidPoint.x--;
}
}
if (myMidPoint.y + viewHeight > targetHeight) {
while (myMidPoint.y + viewHeight > targetHeight) {
myMidPoint.y--;
}
}
resizedBitmap = Bitmap.createBitmap(bitmapOrg,
(int) (myMidPoint.x - myEyesDistance),
(int) (myMidPoint.y - myEyesDistance),
viewWidth, viewHeight, matrix, true);
} else {
resizedBitmap = Bitmap.createBitmap(bitmapOrg, 0, 0,
viewWidth, viewHeight, matrix, true);
}
/* convert Bitmap to resource */
// Bitmap resizedBitmap = Bitmap.createBitmap(targetBitmap,
// 0,
// 0, viewWidth, viewHeight, matrix, true);
BitmapDrawable bd = new BitmapDrawable(resizedBitmap);
iv1.setBackgroundDrawable(new BitmapDrawable(
getCroppedBitmap(bd.getBitmap())));
} catch (Exception e) {
System.out.println("Error1 : " + e.getMessage()
+ e.toString());
}
iv1.invalidate();
}
else if (resultCode == RESULT_OK && imgNo == 2)
{
Bitmap photo = (Bitmap) imageReturnedIntent.getExtras().get("data");
iv2.setImageBitmap(photo);
// path2 = imageReturnedIntent.getData().getPath();
bmpimg2 = photo;
iv2.invalidate();
}
}
}
ただし、画像は切り抜かれていません。どうやってイメージから顔を切り取ることができますか？どんな助言も大きな助けになる。作物へ
