If you want different levels of transparency you need different
alpha values. Currently you always set the transparency to 0x7F.
You need some kind of if statement:
if (floatData[i] > <threshold>)
intData[i] = alpha | ((int)(floatData[i] * scaleFactor) &
0x00ff0000)); // mask off the non-red bits
else
intData[i] = 0x00 | ((int)(floatData[i] * scaleFactor) &
0x00ff0000)); // mask off the non-red bits
The else clause could also be:
inData[i] = 0;
Since if it is completely transparent you don't really care what
the 'color' is...
