Hi again,
I found finally how to remove the problem but I am not satisfied at
all by the result.
Let me summarise. Problem was that while drawing on the graphics
created from a VolatileImage using an affine transform I was getting
poor results, low quality and strange color. I updated to jdk1.5, I
disabled the rendering hints for quality that I was using by
commenting them out as follows
// g2D.setRenderingHint(RenderingHints.KEY_RENDERING,
// RenderingHints.VALUE_RENDER_QUALITY);
// g2D.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
// RenderingHints.VALUE_ANTIALIAS_ON);
// g2D.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
// RenderingHints.VALUE_INTERPOLATION_BILINEAR);
and all problems disappeard. Unfortunately now the quality is poor
since I have no antialiasing. How can I solve this problem while still
having good quality?
Simone.
