수다닷컴

이미지 타입이 rgb가 아니라 cmyk라 ImageIO.read()로 부르면Exception in thread main javax.imageio.IIOException: Unsupported Image Typeat com.sun.imageio.plugins.jpeg.JPEGImageReader.readInternal(Unknown Source)at com.sun.imageio.plugins.jpeg.JPEGImageReader.read(Unknown Source)at javax.imageio.ImageIO.read(Unknown Source)at javax.imageio.ImageIO.read(Unknown Source)at pnTestSource.ImageMagicTest.main(ImageMagicTest.java:33)이런 에러가 납니다.그래서com.sun.image.codec.jpeg.JPEGImageDecoder jpegDecoder = JPEGCodec.createJPEGDecoder (new FileInputStream(filePath));BufferedImage image = jpegDecoder.decodeAsBufferedImage();이런식으로 이미지를 불러왔는데반전이미지 처럼 색이 변해버려서 저장이 됩니다.구글 여기저기를 다 뒤져봤는데 imageMagick을 쓰면 변환이 가능하다고는 하는데 jdk환경이 32비트만 지원을 하는지라...저는 64비트를 쓰고 있습니다.뭔가 해결 방법이 있을까요...

아래는위에 말한 소스 입니다.
