== Header ==
== Format ==
 
The SCAN format is very simple; it has a header with data that contains general settings related to the scan, and then four structs defining how the scan images work. Even if a scan doesn't use four images, there's always four image structs, which means the SCAN format has a static size; every SCAN file is 0x89 bytes (or 0xA0 bytes padded).
 
=== Header ===


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

==== Logbook Category ====


== Entry ==
There's five possible values:
 
{| class="wikitable"
! ID
! Category
|-
| 0
| Not a logbook scan
|-
| 1
| Space Pirate Data
|-
| 2
| Chozo Lore
|-
| 3
| Creatures

| 4
| Research
|}
 
=== Scan Images ===

Following the header is an array of 4 structs which follow this format:
Following the header is an array of four structs that contain settings for up to four scan images. Although there can be anywhere from 0 to 4 scan images attached to a scan, there are always four scan image entries here. Entries that aren't used have their TXTR ID set to 0xFFFFFFFF, with the rest of the settings mostly left at defaults. They follow this format:


{| class="wikitable"
{| class="wikitable"

| '''[[TXTR (Metroid Prime)|TXTR]] ID'''
|-
|-
| 0x4
| 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.
| float
| '''Appearance %'''; image will appear when the scan is this% complete
|-
|-
| 0x8
| 0x8
| 4
| 4
| {{unknown|'''Unknown (Fade in duration?)''' - long}}
| long
| {{unknown|'''Unknown (Fade in duration?)'''}}
|-
|-
| 0xC
| 0xC
| 4
| 4
| {{unknown|'''Unknown''' - long}}
| long
| {{unknown|'''Unknown'''}}
|-
|-
| 0x10
| 0x10
| 4

| {{unknown|'''Unknown''' - long}}
| long
| {{unknown|'''Unknown'''}}
|-
|-
| 0x14
| 0x14

| {{unknown|'''Unknown''' - long}}

| {{unknown|'''Unknown'''}}
|-

| {{unknown|'''Unknown''' - float}}
| float
| {{unknown|'''Unknown'''}}
|-
|-
| 0x1C
| 0x1C
| colspan=2 {{unknown|End of entry}}
| colspan=3 {{unknown|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.
