32x32 Chinese font modulo description

• 32x32中文字体取模说明

尺寸设置如下图所示：

取模成功后需要定义以下结构体数组存放取模数据（结构体定义见中英文显示取模设置）：

const typFNT_GB32 tfont32[]=
{
  "中",0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x01,0x00,0x00,0x00,0x01,0x80,0x00,
  0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,
  0x08,0x01,0x80,0x30,0x0F,0xFF,0xFF,0xF0,0x0C,0x01,0x80,0x20,0x0C,0x01,0x80,0x20,
  0x0C,0x01,0x80,0x20,0x0C,0x01,0x80,0x20,0x0C,0x01,0x80,0x20,0x0C,0x01,0x80,0x20,
  0x0C,0x01,0x80,0x20,0x0C,0x01,0x80,0x20,0x0F,0xFF,0xFF,0xE0,0x0C,0x01,0x80,0x20,
  0x0C,0x01,0x80,0x20,0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,
  0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,
  0x00,0x01,0x80,0x00,0x00,0x01,0x80,0x00,0x00,0x01,0x00,0x00,0x00,0x00,0x00,0x00,
};

函数定义如下：

void GUI_DrawFont32(u16 x, u16 y, u16 fc, u16 bc, u8 *s,u8 mode)
{
    u8 i,j;
    u16 k;
    u16 HZnum;
    u16 x0=x;
    HZnum=sizeof(tfont32)/sizeof(typFNT_GB32);	//自动统计汉字数目
    for (k=0;k<HZnum;k++) 
    {
	 if ((tfont32[k].Index[0]==*(s))&&(tfont32[k].Index[1]==*(s+1)))
	 { 	
               LCD_SetWindows(x,y,x+32-1,y+32-1);
	       for(i=0;i<32*4;i++)
	       {
		     for(j=0;j<8;j++)
	             {
			   if(!mode) //非叠加模式：字体带有背景色，显示时会将原来显示的内容覆盖掉
			   {
				if(tfont32[k].Msk[i]&(0x80>>j))
                                {
				      Lcd_WriteData_16Bit(fc);
                                }				
				else 
                                {
                                      Lcd_WriteData_16Bit(bc);
				}			
                           }
			   else //叠加模式：字体不带背景色，直接叠加显示到原来显示的内容上
			   {
				POINT_COLOR=fc;
			        if(tfont32[k].Msk[i]&(0x80>>j))
                                {
                                      LCD_DrawPoint(x,y);// 画一个点
				}		
		                x++;
				if((x-x0)==32)
				{
				      x=x0;
				      y++;
				      break;
				}
			   }
		      }
		}
	  }				  	
	  continue;  //找到对应点阵字库立即退出，防止多个汉字重复取模带来影响
     }
     LCD_SetWindows(0,0,lcddev.width-1,lcddev.height-1);// 恢复窗口为全屏
}
