Convert RGB color to 16 bit color

0x3f before the 8bit, and clear the 3bit or 2bit before the 8bit. The following three components are obtained: r = 000 rrrrr, G = 00 gggggg, and B = 000 bbbbb. Finally, you can shift them to a 16-bit565 color. The formula is as follows:Color16bit = (getrvalue (colorrgb)> 3) 0x1f) (Getgvalue (colorrgb)> 2) 0x3f) (Getbvalue (colorrgb)> 3) 0x1f;In fact, there is no need to compare it with 0x1f and 0x3f, be
