bft font image

It contains font table and graphic data, however I don't have an idea how to get texture. Does any one can look at it?

Here's what I found out about the file format:

Code: Select all

// main_font_sdw_vita.unpack

byte header[12]; // it's the same in both .unpack files

int characterCount;

struct charInfo {
  short keycode;
  byte zero; // always zero
  byte xOffset; // not sure about the offsets
  byte yOffset;
  byte horOffset;
  byte charWidth;
  byte charHeight;
  int unknown; // initial value = 0x55800000, increases by 0x56 each line
};


// @0x1525C

struct charData {
  byte charBitmap[19 * 36];
  int unknown; // alwys zero? padding?
};


// @0x4D160C
// don't know what that section is

int unknownCount;

struct unknown {
  short;
  short;
  int;
};

The font characters are simple 8-bit grayscale bitmaps with a fixed size of 19x36 pixels per character.
Here's a screenshot of the characters in main_font.unpack, mapped onto a 1024 pixels wide texture atlas:

Oh, did you open it as a raw file from Photoshop? Is there a specific height?

Actually I wrote a simple java program that converts the font file into a raw image.

Uhm.. unfortunately I had never learned Java.

Uhm.. unfortunately I had never learned Java.

just drop your samples in the folder with the fontToRaw java files
open a command prompt there and type
java fontToRaw
press Enter then it'll ask for a file name like this
Enter filename:
then you can type the name of your sample file and press Enter
and you will get a raw image file of that sample in that folder
that you can open in Photoshop with the dimensions in the file name

@adol365: Just a quick question. At the current state the program outputs this data:
https://www.mediafire.com/?7acvohe2y3tcb79
Is this sufficient for you to edit the font? If yes, I could start to write the repacker.

Yes, it is sufficient for me. By the way, is horOffset means xadvance?

[herbert3000]

I pretty sure I mixed up the offsets (x/y/hor).
The value that is currently named horOffset is high for characters like "." and "," so I think that's the actual y-offset, is that possible?

But isn't you already declare yoffset before horOffset?
I'm not sure exactly what horOffset means but it doesn't quiet matter if one can make a new font.

xOffset, yOffset and horOffset were my first guess for the last 3 values but I guess I was wrong
If you figure out the true meaning, I can correct that in the program.

But you are right, for making a new font, the names of the keywords are irrelevant.
I should have named them unknown1, unknown2 and unknown3

In my opinion, the easy way to confirm what is the meaning of UNK1, 2, 3 is that modify fnt table data and take a test in the game.

Here's a converter for the file main_font.unpack:

FontTools.zip

Usage: Run the .bat file,
to unpack the file enter: main_font.unpack
to repack the file enter: main_font.unpack.txt

Backup your original files because this tool will overwrite existing files without confirmation.
