방법: 이미지의 일부에 효과 적용

업데이트: 2007년 11월

이 예제에서는 BitmapEffectInput 속성을 사용하여 Image 일부분에 BitmapEffect를 적용하는 방법을 보여 줍니다.

다음 예제에서는 시각적 콘텐츠 일부분에 효과를 적용하는 두 가지 방법을 보여 줍니다.

               AreaToApplyEffect is a rectangular area in which to apply the effect.
               - When AreaToApplyEffectUnits is "Absolute", the rectangle is read as
                 pixel coordinates within the visual.
               - When AreaToApplyEffectUnits is "RelativeToBoundingBox",
                 the rectangle values are relative to the entire bounding box.
                 Values range between 0 and 1, where (0,0) is the top-left corner

다음 그림에서는 이미지 중간에만 적용된 볼록 효과를 보여 줍니다.
