public static BufferedImage readImageFromCMYK(InputStream in,
 ICC_Profile cmykProfile)
                                       throws IOException

Reads a CMYK JPEG image from the provided InputStream, converting the colors to RGB using the provided CMYK ICC_Profile. The image data must be in the CMYK color space.

Use this method, if you have already determined that the input stream contains a CMYK JPEG image.

Parameters:

in - An InputStream, preferably an ImageInputStream, in the JPEG File Interchange Format (JFIF).

cmykProfile - An ICC_Profile for conversion from the CMYK color space to the RGB color space. If this parameter is null, a default profile is used.

Returns:

a BufferedImage containing the decoded image

Throws:

IOException

Reads a RGBA JPEG image from the provided InputStream, converting the colors to RGBA using the provided RGBA ICC_Profile. The image data must be in the RGBA color space.

Use this method, if you have already determined that the input stream contains a RGBA JPEG image.

Parameters:

in - An InputStream, preferably an ImageInputStream, in the JPEG File Interchange Format (JFIF).

rgbaProfile - An ICC_Profile for conversion from the RGBA color space to the RGBA color space. If this parameter is null, a default profile is used.

Returns:

a BufferedImage containing the decoded image.

Throws:

IOException

Parameters:

in - An InputStream, preferably an ImageInputStream, in the JPEG File Interchange Format (JFIF).

cmykProfile - An ICC_Profile for conversion from the CMYK color space to the RGB color space. If this parameter is null, a default profile is used.

Returns:

a BufferedImage containing the decoded image.

Throws:

IOException

readImageFromInvertedYCCK

public static BufferedImage readImageFromInvertedYCCK(InputStream in,
