Method Detail

read

public static JPEGImage read(InputStream in,
             TextureData.ColorSpace cs)
                      throws IOException

Reads a JPEG image from the specified InputStream, using the given color space for storage.

Parameters:

in -

cs - Storage color space, either TextureData.ColorSpace.RGB or TextureData.ColorSpace.YCbCr. TextureData.ColorSpace.YCCK and TextureData.ColorSpace.CMYK will throw an exception!

Returns:

Throws:

IOException

read

public static JPEGImage read(InputStream in)
                      throws IOException
