[JAVA2D] spectrogram: gray to color

[Aldebaro Klautau]

Hi,   I have a gray version of a speech spectrogram (in my case, float numbers that are represented by a gray-level image) and I need to convert it to a colorful version. I found some related information in the Java2D list archive and I think I can quantize the samples to 12 bits (for example) and split the bits into 3 channels (4 bits/channel). Is there a more efficient way ? Suggestions are welcome.   Thanks a lot, Aldebaro ============================================================ Aldebaro B. R.
