Understanding the FontCreator output

[lyubomyr]

Hello.

First of all, thank You for the great font generating tool!!!

I want to understand the output format properly. I generated some font (letters A to F). I have put some comments below. Please, correct me where I am wrong


const unsigned short Tahoma13x14[] = {
0x00, // what is this??
0x00, // what is this??
0x41,0x00, // number if the first char in ASCII table. Here 0x41 = 65 = Letter A
0x46,0x00, // number if the last char in ASCII table. Here 0x46 = 70 = Letter F
// above values are calculated as NumbOfLetter = 0x00*0xFF + 0x41 => to decimal (if needed)
0x0E, //number of rows 0x0E = 14
0x00, //what is this??
0x0C,0x20,0x00,0x00, // the first number (0x0C) is number of collumns occupied by letter A
// next numbers are coordinates of the first hex data which corresponds to letter A. They are calculated 0x00*0xFF*0xFF+ 0x00*0xFF+ 0x20. And this mean that ellement 32 of the array Tahoma13x14[] is the ferst hex number that stands for lettar A
0x0B,0x3C,0x00,0x00,
0x0B,0x58,0x00,0x00,
0x0D,0x74,0x00,0x00,
0x0B,0x90,0x00,0x00,
0x0B,0xAC,0x00,0x00,

//below data corresponds ONLY to letters and can be used without modification 0xE0,0x00,0xE0,0x00,0xE0,0x00,0xB0,0x01,0xB0,0x01,0xB0,0x01,0x18,0x03,0x18,0x03,0xF8,0x03,0xFC,0x07,0x0C,0x06,0x0C,0x06,0x0E,0x0E,0x06,0x0C, // Code for char num 65
0xFC,0x01,0xFC,0x03,0x0C,0x03,0x0C,0x03,0x0C,0x03,0x8C,0x01,0xFC,0x00,0xFC,0x03,0x0C,0x07,0x0C,0x06,0x0C,0x06,0x0C,0x07,0xFC,0x03,0xFC,0x01, // Code for char num 66
0xF0,0x03,0xF8,0x07,0x1C,0x04,0x0C,0x00,0x06,0x00,0x06,0x00,0x06,0x00,0x06,0x00,0x06,0x00,0x06,0x00,0x0C,0x00,0x1C,0x04,0xF8,0x07,0xF0,0x03, // Code for char num 67
0xFC,0x01,0xFC,0x07,0x0C,0x0F,0x0C,0x0C,0x0C,0x18,0x0C,0x18,0x0C,0x18,0x0C,0x18,0x0C,0x18,0x0C,0x18,0x0C,0x0C,0x0C,0x0F,0xFC,0x07,0xFC,0x01, // Code for char num 68
0xFC,0x07,0xFC,0x07,0x0C,0x00,0x0C,0x00,0x0C,0x00,0xFC,0x07,0xFC,0x07,0x0C,0x00,0x0C,0x00,0x0C,0x00,0x0C,0x00,0x0C,0x00,0xFC,0x07,0xFC,0x07, // Code for char num 69
0xFC,0x07,0xFC,0x07,0x0C,0x00,0x0C,0x00,0x0C,0x00,0x0C,0x00,0xFC,0x07,0xFC,0x07,0x0C,0x00,0x0C,0x00,0x0C,0x00,0x0C,0x00,0x0C,0x00,0x0C,0x00 // Code for char num 70
};


Please, help me understand the lines (values) of the array that I can't figure out (blue). Are green comments correct?

Hi,

The Glcd Font Creator creates the fonts according to the Microchip Graphics Library document :
