使用linux下的ImageMagick自带的convert命令，进行raw格式转换，命令为：
　　convert -depth 8 initlogo.png rgb:initlogo.raw

注：ubuntu 10.04 默认已经安装ImgageMagick工具，如果当前系统没有安装，可以执行下面的命令安装：
　　sudo apt-get install imagemagick

< void android_memset24(void *_ptr, unsigned short val, unsigned count)
< {
<     unsigned char *ptr = (unsigned char *)_ptr;
<     count >>= 1;
<     while(count--) {
<         *ptr++ = ((val&0x001F )<<3);//B
<         *ptr++ = ((val&0x07E0 )>>3);//G
<         *ptr++ = ((val&0xF800 )>>8);//R
<         ptr++;//the forth byte not use
<     }
< }
