The BFLIM file format (Binary caFe Layout IMage) is used to store layout images.

Header

The header is at the end of the file (to align the image data without the need for additional padding). It is always 0x14 bytes.

Offset	Size	Type	Description
0x00	4	Char[4]	File magic. Always FLIM in ASCII.
0x04	2	UInt16	Byte Order Mark (BOM): 0xFEFF for big endian and 0xFFFE for little endian. Not handled on consoles, so the file data must be stored in the endianness of the target console (e.g. big endian for the Wii U).
0x06	2	UInt16	Header size, always 0x14.
0x08	4	UInt32	Version of this file.
0x0C	4	UInt32	File size in bytes.
0x10	2	UInt16	Number of data blocks, always 0x01.
0x12	2	UInt16	Padding. Seems to reflect upper 2 bytes of filesize (apparently uninitialized memory garbage from file generator).
0x14	End of FLIM header

A section containing image information comes directly after header. It is always 0x14 bytes long.

Offset	Size	Type	Description
0x14	4	Char[4]	Section magic. Always imag in ASCII.
0x18	4	UInt32	Parse information size (total block size), always 0x10 (this and next 0xC bytes).
0x1C	2	UInt16	Width of the texture in pixels.
0x1E	2	UInt16	Height of the texture in pixels.
0x20	2	UInt16	File alignment, always a power of 2. Usually 0x800, 0x1000 or 0x2000.
0x22	1	Byte	Format, how the data is stored.
0x23	1	Byte	Tile mode and Swizzle, packed as bits SSSTTTTT. TTTTT maps to GX2TileMode (line 795 here). Typically GX2_TILE_MODE_2D_TILED_THIN1 (4). SSS is the swizzle value shifted right by 8.
0x24	4	UInt32	Raw data size, always 0xC minus 0x28 (the header).
0x28	End of Image header
