How to use Chinese Character Matrix Library
It was a fashion to read Chinese Character Matrix Library (CCML) and display chinese character
without chinese operation system. It's critical when we only had 640K memory,
and 40M hard drive. But now it can only be used in Industrial Control Fields.
This is the result of development of hardware, and greatly waste of memory, like Windows.
Let's observe CCML:
Characters in Matrix 16*16 Library are listed by their Code, and there are 32 bytes (256 bits)
for every character. For example, the information of a character 
should be saved like this:
0000000000000000
0000000110000000
0000000110000000
0000000110000000
0011111111111100
0011111111111100
0011000110001100
0011000110001100
0011000110001100
0011000110001100
0011111111111100
0011111111111100
0000000110000000
0000000110000000
0000000110000000
0000000000000000
So that the Code should be:
0x00, 0x00, 0x01, 0x80, 0x01, 0x80, 0x01, 0x80, 0x3f, 0xfc, 0x3f, 0xfc......
Now, you read the code, then you should display it (use putpixel in Turbo C)
in proper sequence.
You can also write display buffer to display like this part
of source code.It's faster.
You can write a Small Character Information Library for further use,
It's also faster.
Here is souce code:
#include < io.h>
#include < graphics.h>
#include < fcntl.h>
#include < dos.h>
#define CCLIB "C:\HZK16"
display(unsigned char *matrix,int x,int y,int color)
{
int i,j,y2;
for(i=0; i < 16; ++i) {
for(j=0; j < 8; ++j)
if (matrix[i+i]&(1 < < (7-j)))
putpixel(x+j,y,color);
for(j = 0; j < 8;++j)
if(matrix[i+i+1]&(1 < < (7-j)))
putpixel(x+j+8,y,color);
y++;
}
}
main()
{ int col,row,handle;
unsigned qh,wh;
unsigned long offset;
unsigned char *hz,hzm[32];
unsigned char cz[]= " " ;
int driver=DETECT, mode=0;
handle= open(CCLIB,O_RDONLY|O_BINARY);
if(handle== -1) {
printf("Can't open the cclib!");
exit(-1);
}
initgraph(&driver,&mode,"");
col=130;row=150;
hz=cz;
while(*hz){
qh=*hz-0xa0;
wh=*(hz+1)-0xa0;
offset=(94*(qh-1)+(wh-1))*32l;
lseek(handle,offset,SEEK_SET);
read(handle,hzm,32);
display(hzm,col,row,12);
col += 16; // Next character.
hz += 2;
}
close(handle);
bioskey(0);
closegraph();
}
In Next Page there's a faster program to show Chinese Characters.
