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. |

int[] |
getTransformedSizes()
Returns an array containing the sizes of the transformed JPEG images
generated by the most recent transform operation.
|
void |
transform(byte[][] dstBufs,
TJTransform[] transforms,
int flags)
Losslessly transform the JPEG image associated with this transformer
instance into one or more JPEG images stored in the given destination
buffers.
|
TJDecompressor[] |
transform(TJTransform[] transforms,
int flags)
Losslessly transform the JPEG image associated with this transformer
instance and return an array of
TJDecompressor instances, each of
which has a transformed JPEG image associated with it. |
