“16*16逐行式順向陰碼”轉“16*16列行式逆向陰碼”字模C程式碼

C程式

前段時間做的專案，從HZK16字型檔中讀取的字模資料是16*16逐行式順向格式的，傳輸給客戶的裝置無法顯示，他們那邊不能改變OLED屏顯示的方式，所以寫了一個簡單的字模轉換演算法；

HZK16的讀取網上一搜就是一大堆，所以這裡就不貼這串程式碼了；

測試的時候可以使用PCtoLCD工具生成兩種不同格式的字模資料對轉換後的字模資料進行校對；

{0x02,0x00,0x01,0x00,0x7F,0xFE,0x40,0x02,0x80,0x04,0x1F,0xE0,0x00,0x40,0x00,0x80},
{0x01,0x00,0xFF,0xFE,0x01,0x00,0x01,0x00,0x01,0x00,0x01,0x00,0x05,0x00,0x02,0x00},/*"字",0*/

{0x10,0x0C,0x04,0x24,0x24,0x24,0x25,0x26,0xA4,0x64,0x24,0x04,0x04,0x14,0x0C,0x00},

{0x02,0x02,0x02,0x02,0x02,0x42,0x82,0x7F,0x02,0x02,0x02,0x02,0x02,0x02,0x02,0x00},/*"字",0*/
