C# HEIC 파일 PNG 로 변환하기

C# HEIC 파일 PNG 로 변환하기

 

HEIC 파일은 아이폰에서 찍은 고화질 이미지 입니다.

이를 C# 에서 Image.FromFile 을 사용하는 경우

아래와 같이 메모리가 부족하다는 에러가 발생됩니다.

 

HEIC 파일은 작업하기 위해서는 'Magick.NET-Q8-AnyCPU' 패키지를 사용하면 처리할 수 있습니다.

 

Nuget Package 설치하고 아래 처럼 처리합니다.

using (var magickImage = new MagickImage("text.HEIC"))
{
    magickImage.Format = MagickFormat.Png;
    // PNG 파일로 저장
    magickImage.Write("test.png");
}

Format 은 다양한 형식을 지원합니다.
