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.
