[hpsdr] [OT] jmonitor waterfall color

[Ken N9VV]

Hi, I asked John for help in changing his EXPERIMENTAL jmonitor 
online display waterfall color. Here is his reply:

-------------- from John Melton --------------
The waterfall pixel color is calculated in the method 
calculatePixel: [in the WaterfallPanel.java]

    int pixel=(255<<24)+(v<<16)+(v<<8)+v;

A pixel if 32 bits:

    255<<24 sets the Alpha value
    v<<16 sets the R value
    v<<8 sets the G value
    v    sets the B value

If you want the waterfall to be shades of Blue then set the R and 
G values to 0:
     int pixel=(255<<24)+(0<<16)+(0<<8)+v;
or
     int pixel=(255<<24)+v;

You can set it to other colors by just combining different 
combinations of RGB.
--------------------------------------------

Experimenting is great fun when we have such an accomplished 
mentor (Elmer) like John to help us along.

I changed my waterfall to shades of blue :-) thank you John.

what a great time to be in Ham Radio and SDR technology.
