The .SCAN file format describes scannable objects, and has references to several resources. It is a relatively simple format and has a static size.

This file format needs more research
Too many unknowns.

Header

The header is rather simple, and consists of the following:

Offset Size Description
0x0 4 Version
0x4 4 Magic; always 0x0BADBEEF
0x8 4 FRME ID
0xC 4 STRG ID
0x10 4 Scan Speed; 0 = Fast Scan, 1 = Slower Scan, usually found in boss fights
0x14 4 Scan Type; 0 = No message, 1 = Pirate Data, 2 = Chozo Lore, 3 = Creatures, 4 = Research
0x18 1 Red Scan Symbol Flag; 0 = Orange symbol, 1 = Red symbol
0x19 End of header


Entry

File:Scan positions1.png
Offsets for the different scan images and their positions
File:Scan positions2.png

Following the header is an array of 4 structs which follow this format:

Offset Size Description
0x0 4 TXTR ID
0x4 4 0.25 Float; when the scan download is 25% finished, display this image. Another 25% is added on to the next float on the next image entry.
0x8 4 Unknown (Fade in duration?) - long
0xC 4 Unknown - long
0x10 4 Unknown - long
0x14 4 Unknown - long
0x18 4 Unknown - float
0x1C End of entry


This pattern repeats, however the next image will be displayed on the right. The third image will be displayed on the right again but for smaller pictures and finally, the fourth image will be displayed on the bottom left corner, again for use for smaller pictures. The float increases with every entry, so the next image will be .50, the third will be .75 and finally the last image will load at 1, when the scan finishes.
