1. 二值图片高为18，宽为16(有效宽度为10)，每一行有2个字节，一个字模共36字节

2. 某ascii值的字模首地址为：fontdata_10x18[id * 36]

3. 这个是等宽字体

//下段代码并不严谨

//实际的情况则需要看根据字库的设计情况,按如下的思路即可

int_t w = 10, h = 18;

unsigned char *pFont = &fontdata_10x18[id * 36];

unsigned char *pData = ptr->pData + y * ptr->pitch + x * ptr->bpp;

for(int j = 0; j < h; j++)

{

unsigned char *pd = pData;

for(int i = 0; i < w; i++)

{

unsigned char *pf = pFont + j * 2 + (i >> 3);

if(*pf & (0x1 << (7 - i & 0x7)))

{

memcpy(pd, &color, ptr->bpp);

}

else if(border)

{

//简单描边算法

int xi = 0, yj = 0;

if(0 < j)
