TJTransformer()
Create a TurboJPEG lossless transformer instance.
|
TJTransformer(byte[] jpegImage)
Create a TurboJPEG lossless transformer instance and associate the JPEG
image stored in
jpegImage with the newly-created instance. |
TJTransformer(byte[] jpegImage,
int imageSize)
Create a TurboJPEG lossless transformer instance and associate the JPEG
image of length
imageSize bytes stored in
jpegImage with the newly-created instance. |

Losslessly transform the JPEG image associated with this transformer
instance into one or more JPEG images stored in the given destination
buffers.

instance and return an array of
TJDecompressor instances, each of
which has a transformed JPEG image associated with it. |
