Hi Thanh,
I send you a simplified vesrion of my classes.
I can send you Sun Raster files if you want.
Just one question:
Where can I find examples about how create a BufferedImage decoder and the use of
the DataBuffer and SampleModel (No examples at Sun or JavaWorld).
In all the examples I have seen, the author use Toolkit.loadImage, create a
BufferedImage with a graphics, and draw the image in the graphics. With this method,
you lost original model of the image.
The JPEGImageDecoder.java use native code so it can't help programmers.
And I use high level methods like ColorModel.createCompatibleWitableRaster(), I
can't precise informations like scanlinestride.May be the problem is here. In the
BufferedImageOp, you use high levels methods to make compatible the source and the
destination.
