File format
Header
| Data type | Description |
|---|---|
| UINT16BE iCount | Number of images |
Image list
A number of image blocks immediately follow the signature byte, repeating iCount times:
| Data type | Description |
|---|---|
| UINT16BE iWidth | Size of this sprite |
| UINT16BE iHeight | Size of this sprite |
| UINT16BE iSize | Length of image data |
| BYTE cData[iSize] | Block of image data, iSize bytes long |
If iSize is zero, that means the image is not compressed and is drawn as-is. If iSize is non-zero, then iSize bytes should be read and decompressed with LBM Format decompression.
