Description:
|
JPEG encoding doesn’t support alpha band.
Before sending the image to the TurboJPEGImageWriter, bandSelect is performed by TurboJPEGImageWorker to remove the alpha band.
When Medialib is available the result is good.
However, when MediaLib isn’t available the resulting image isn’t good (it is a bit stretched and dark lines are present).
It seems like the pure java BandSelect op doesn’t properly operate on the underlying DataBuffer when creating a child of the original tile or some other strange things are occurring within the Oracle ByteInterleavedRaster class.
We should investigate on it or create an utility method inside the TurboJpegImageWorker which uses a different approach to do bandSelect when no MediaLib is available.
