프레임 내 마스킹 (자르기) 이미지

프레임 내 마스킹 (자르기) 이미지

---

이렇게 복잡한 모양의 이미지를 보여주고 싶은 풍부한 UI 애플리케이션이 있습니다.

이제 내가 원하는 것은 마스크 이미지에 따라 이미지를 자르는 것입니다. 실제로 이미지는 동적이며 카메라 또는 갤러리 (정사각형 또는 직사각형 모양)에서 가져올 수 있으며 해당 이미지가 위와 같이 내 레이아웃 프레임에 맞기를 원합니다.

그래서 어떻게 이것을 달성했는지 궁금하십니까? 모든 아이디어 / 힌트 환영

마침내 마스크 이미지를 변경하고 Xfermodewith를 사용하면서 해결책을 얻었습니다.Bitmap

마스크

 ImageView mImageView= (ImageView)findViewById(R.id.imageview_id);
 Bitmap original = BitmapFactory.decodeResource(getResources(),R.drawable.content_image);
 Bitmap mask = BitmapFactory.decodeResource(getResources(),R.drawable.mask);
 Bitmap result = Bitmap.createBitmap(mask.getWidth(), mask.getHeight(), Config.ARGB_8888);
 Canvas mCanvas = new Canvas(result);
 Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);
 paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.DST_IN));
 mCanvas.drawBitmap(original, 0, 0, null);
 mCanvas.drawBitmap(mask, 0, 0, paint);
 paint.setXfermode(null);
 mImageView.setImageBitmap(result);
 mImageView.setScaleType(ScaleType.CENTER);
 mImageView.setBackgroundResource(R.drawable.background_frame);

Picasso 라이브러리와 사용자 지정 변환을 사용하는 것이 훨씬 더 쉽습니다.

    public MaskTransformation(Context context, int maskId) {

        int height = source.getHeight();

        Bitmap result = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);

}

그런 다음 간단히 한 줄로 정의합니다.

Picasso.with(context)
                    .load(imageUrl)
                    .transform(new MaskTransformation(context, _maskDrawableId))
                    .placeholder(R.drawable.drawableId)
                    .into(imageView);
