Isle of the Dead Font Format

Nrich: New page for Isle of the Dead Font Format

{{Font Infobox
| MaxGlyphs = 89
| GlyphMinSize = 0×0
| GlyphMaxSize = 255×255

The font used in the game [[Isle of the Dead]] is a monochrome bitmap font, which starts at the exclamation(!) character (0x21) and contains 89 characters, meaning it goes up to 0x7A (z). For some reason, the space character is mapped to 0x5F.

===Header===

{|class="wikitable"
!Offset!!Data type!!Name!!Description
|-
|0x00||[[UINT8]]||Width||Symbol width
|-
|0x01||[[UINT8]]||Height||Symbol height
|-
|0x02||[[UINT16]]||Padding||Unused (zero filled)
|-
|0x04||[[UINT16]]||Count||Number of symbols in this file
|-
|0x06||[[UINT8]][12]||Name||Font name
|}

=== Image data ===

Each symbol is defined as a bitmap of pixels, with each byte describing a pixel in the bitmap.

As an example, the exclamation point character is defined as:

0x00, 0x00, 0x00, 0x00, 0x00
0x00, 0x00, 0x01, 0x00, 0x00
0x00, 0x00, 0x01, 0x00, 0x00
0x00, 0x00, 0x01, 0x00, 0x00
0x00, 0x00, 0x01, 0x00, 0x00
0x00, 0x00, 0x01, 0x00, 0x00
0x00, 0x00, 0x00, 0x00, 0x00
0x00, 0x00, 0x01, 0x00, 0x00

To calculate a symbol's image data in the file is simple; take the symbol's ascii code, subtract 0x21 (to compensate for the start symbol), multiply by (width*height), and add 0x12 (to compensate for the header).

CEL Image Format

2025-11-03T11:12:37Z

Nrich: New page describing CEL image format.

{{Image Infobox
| Hardware1 = VGA
| Depth = 8-bit (VGA)
| MinSize = 0×0
| MaxSize = 65535×65535
| Palette = Internal or external
| NumPlanes = 1
| HasTransparency = Yes
| HasHitmap = No
| Games = {{Game|Isle of the Dead}}
}}

The '''CEL Image Format''' is used by [[Isle of the Dead]] for all in game graphics. There are 2 distinct file formats used, but confusingly both use the .CEL file extension.

All .CEL files in the '''CELS3''' directory are simple 64×64 8-bit VGA images using an external colour palette. These files are used for in-world items and enemy sprites.

All .CEL files in the '''STILLCEL''' are variable size VGA images using an colour palette defined inside the file. A more detailed format is given below.

== Signature ==

The first 2 bytes are the file are always 0x1991.

== File format ==

{|class="wikitable"
! Data type !! Name !! Description
|-
| [[UINT16LE]] || Signature|| Always the value 0x1991
|-
| [[UINT16LE]] || width || Width of the image, in pixels
|-
| [[UINT16LE]] || height || Height of the image, in pixels
|-
| [[UINT8]][26] || description || File description? Sometimes the file name, mostly zero filled
|-
| [[UINT8]][width * height] || pixelData || Pixel data
|-
| [[UINT8]][768] || palette || 256×3 6-bit RGB colours
