Palm Programming Tutorial(BmpSetTransparentValue)

For the BmpSetTransparentValue() function, tr are two arguments one is the bitmap pointer, and the other is the transparent value.

In my app, I have used pure wite transparent color, and I set it 0xFFFF

BmpSetTransparentValue((BitmapType*)bmpV3, 0xFFFF);

make 5-6-5 bitmap coding (16bit)
RGBColorType color;
//UInt8 R,G,B ( color.r, color.g, color.b )

R = (R-7) / 8;
G = (G-3) / 4;
B = (B-7) / 8;
put all colors to one value
UInt16 color = (R<<11) | (G<<5)>| B;
