<h1>标准库函数 - get_eng_font</h1>
<p>原型extern void get_eng_font(char ch, char *buf, int mode);</p>
<p>用法:#include &lt;system.h></p>
<p>功能:取英文字符的点阵</p>
<p>说明把字符ch的点阵信息存放在buf中。</p>
<pre>
buf必须有足够的空间容纳返回的数据。
mode=0时返回8x16点阵信息mode=1时返回8x8点阵信息。
</pre>
举例:<pre>
// get_eng_font.c
#include &lt;system.h>
main()
{
char buf[32];
char *s="Global View",*p;
int i,j,k; // Loop variable
int x=0,y=0; // screen location to display HZ
int r; // current byte
clrscr();
gotoxy(10,10); // Hide Cursor
x=y=0;
p=s;
while(*p)
{
get_eng_font(*p,buf,0);
for(j=0;j<16;j++)
{
r=buf[j];
for(k=0;k<8;k++)
{
putpixel(x+k,y+j,((r&lt;&lt;k)&0x80)?1:0);
}
}
p++; // forward to next character
x+=8;
}
x=0,y=16;
p=s;
while(*p)
{
get_eng_font(*p,buf,1);
for(j=0;j<8;j++)
{
r=buf[j];
for(k=0;k<8;k++)
{
putpixel(x+k,y+j,((r&lt;&lt;k)&0x80)?1:0);
}
}
p++; // forward to next character
x+=8;
}
getchar();
return 0;
}
