그래서 이전에 여기에 나온 이미지의 크기를 조정하는 방법을 사용하고 있으며 처리하는 초기 이미지에 효과적이지만 두 번째로 프로세스를 사용합니다. 엄지 손톱에 사용할 작은 이미지를 만듭니다. 이 두 번째 엄지 손톱이 만들어지면 검정색 배경이 투명 해져야합니다. 비슷한 불만과 함께 여기에 많은 실을 보았 기 때문에 이것이 일반적인 문제라는 것을 알고 있습니다. 나는 PHP는 오류 로그에서 지난 밤에보고 때 그것은 ..... 그 imagecolorat이 범위를 벗어 났 픽셀을 칠려고 말한 일이 뭐죠PHP - 작은 이미지의 투명도 문제
는PHP Notice: imagecolorat(): 0,28 is out of bounds in C:\inetpub\
은 적어도 나는 알고 있지만 내가 알아야 할 사항 지금 그것을 고치는 방법입니다. 정말 이상한 같은 이미지의 큰 복사본에 대한 나는이 오류를 전혀받지 못한다. 그리고 더 큰 업로드 된 사본의 멋진 사본을 만드는 것은 훌륭하게 작동한다. 나는 모든 것이 처음 실행을 위해하지만 방귀 두 번째 실행에 어떤 이유로 잘 작동과 범위 오류 아웃을 던져 말했듯이
