TBG Image Files

The TBG format is the main image format the game uses. It is extremely simple and uncompressed. Unlike in the archive files the numbers in TBG images are stored in the little endian format (the regular one on Intel CPUs).

Header

Offset	Type	Name	Description
0x00	int32	magic	Magic number (always "tbg\0")
0x04	uint32	data_offset	Offset of the image data
0x08	uint32	data_length	Length of the image data
0x0C	uint32	width	Width of the image in pixels
0x10	uint32	height	Height of the image in pixels
0x14	uint32	flags	Contains information about the format. Usually the first three bytes are 0x00 0x10 0x00 and the last one defines the pixel format. I could not yet find any system behind this format but the only two values I have encountered so far are 0x98 for BGR (24 bits per pixel) and 0x0C for BGRA (32 bits per pixel).
0x18	uint32	image_count	Probably the image count, is always 1. But could be everything to be honest.
0x1C	uint32	unkn1	Unknown, usually 0
0x20	uint32	unkn2	Unknown, usually 0
0x24	float32	resx	Horizontal resolution (probably, is always 1)
0x28	float32	resy	Vertical resolution (probably, is always 1)

After this header a segment of zeros follows up to position 0x33C (828) that does not seem to have any use. After this the data segment starts.

Data Segment

The offset and length of the data segment is defined in the header. It consists of raw pixel data, line by line, in the format defined in the header (BGR or BGRA).
