Hi,

  I'd like to transform a colored picture (from a gif or jpeg file for
exemple) in a Black and White image (wbmp format). I use a
ColorConvertOp to do that, but I don't know how to param it to have a nice
conversion, not a pixel level conversion. Here is the code I used:

BufferedImage bi4 = new BufferedImage(bi3.getWidth(), bi3.getHeight(),

BufferedImage.TYPE_BYTE_BINARY);
ColorConvertOp cco2 = new
ColorConvertOp(ColorSpace.getInstance(ColorSpace.CS_GRAY), null);
cco2.filter(bi3, bi4);

Where bi3 is my original BufferedImage.

Do you know where I can find more information on this conversion, because in
the help I don't understand everything (I have no knowledge on picture
conversion).

Thanks for all

Vincent
