[PYTHON/PILLOW] filter 함수 : 커스텀 필터 사용하기

■ filter 함수에서 커스텀 필터를 사용하는 방법을 보여준다.

▶ 예제 코드 (PY)


from PIL import Image
from PIL import ImageFilter

kernel = ImageFilter.Kernel((3, 3), [1, 0, -1, 5, 0, -5, 1, 0, 1])

pngImageFile = Image.open("source.png")

grayscaleImage = pngImageFile.convert("L")

filterImage = grayscaleImage.filter(kernel)

filterImage.show()
