BMP 16Bit转成32Bit和8Bit的问题~!
数据源是128*128*16(16Bit)的图像,已经被解码了,
const unsigned char bitMapData[]=
{
0x76,0x3b,0x76,0x3b,0x76,0x3b,0x76,0x3b,0x76,0x3b,

像这样的数据源...
在Linux QT上实现,因为现有的QT版本不支持16Bit图像显示.....

16转32：
red = (((pixel) >> 8) & 0xf8)
green = (((pixel) >> 3) & 0xfc)
blue = (((pixel) << 3) & 0xf8)
pixel为16位的像素，
把rgb分别赋给32bits的bmp，最后把32bits的透明色置零，就可以了
16转8：
现建一个通用的调色板，然后对每一个像素置为调色板的近似index就可以了Top

如果不要求细节的话
可以用DESTop
