TAG_DCT_ENCODE_VERSION
public static final int TAG_DCT_ENCODE_VERSION

TAG_APP14_FLAGS0
public static final int TAG_APP14_FLAGS0
The convention for TAG_APP14_FLAGS0 and TAG_APP14_FLAGS1 is that 0 bits are benign. 1 bits in TAG_APP14_FLAGS0 pass information that is possibly useful but not essential for decoding.0x8000 bit: Encoder used Blend=1 downsampling

TAG_APP14_FLAGS1
public static final int TAG_APP14_FLAGS1
The convention for TAG_APP14_FLAGS0 and TAG_APP14_FLAGS1 is that 0 bits are benign. 1 bits in TAG_APP14_FLAGS1 pass information essential for decoding. DCTDecode could reject a compressed image, if there are 1 bits in TAG_APP14_FLAGS1 or color transform codes that it cannot interpret.- See Also:
