Hi,
In a certain piece of code we were using
Jai to dither a rendering of our chart objects, however this caused some
performance issues and we noticed the RenderingHints.KEY_DITHERING
so we tried moving the dithering
into the rendering of the chart that was already using the graphics2D of
a
Hi Eric,
final BufferedImage buf = new BufferedImage(Math.round(fWidth*scale),
Math.round(fHeight*scale), BufferedImage.TYPE_BYTE_BINARY, new
Well, here's you problem. You're creating a binary image, with
only two possible colors. So the dithering can't be smooth by
definition - each
Hi Erik,
There are likely 2 different issues that you are dealing with here.
First is the issue of dithering during drawing vs. during imaging. We
currently do dithering when rendering an image into a lower color
resolution destination, but we don't do any dithering at all when we do
draw and

Hi all!
I have the following problem: I have a Buffered image, then I want to
transcode it into as small as possible format for
wireless transfer. The most suitable format is PNG and since the
wireless devices usually only support monochrome
images, I want to encode the image in this mode.
Samo,
While this does not directly reply to your question please note that 8-to-1 bit
dithering is possible using Java Advanced Imaging. Sample code for dithering
using the ErrorDiffusion and OrderedDither operations is provided at
