This is the format for resources of type GFXRES (these have the extension
|
|
.ani in the original source).
|
|
|
|
Everything is stored MSB first unless otherwise specified.
|
|
|
|
position length meaning
|
|
4 0xffffffff if the file is uncompressed.
|
|
Otherwise, the file is compressed. When uncompressed, the
|
|
file complies with the rest of the format as described
|
|
below.
|
|
4 Unused in file, always 0x00000000
|
|
4 FlagsAndIndex:
|
|
bits 0-11: 1 less than the number of frames in this
|
|
graphics resource
|
|
bits 12-15: flags:
|
|
- bit 0: (WANT_MASK)
|
|
- bit 1: (WANT_PIXMAP)
|
|
- bit 2: (WANT_COMPRESSED)
|
|
- bit 3: (DOUBLE_RES)
|
|
bits 16-31: unknown (0x0000)
|
|
|
|
Frame descriptions:
|
|
Then for all frames:
|
|
4 Type index and flags (TypeIndexAndFlags)
|
|
Low 2 bytes:
|
|
bits 0-11 is the index of this frame
|
|
bits 12-15 are the type flags:
|
|
- bit 12-13:
|
|
- 0: (ROM_DRAWABLE)
|
|
- 1: Direct drawable (RAM_DRAWABLE)
|
|
- 2: (SCREEN_DRAWABLE)
|
|
- 3: (OVERLAY_DRAWABLE)
|
|
High 2 bytes (frame flags):
|
|
- bits 0-7: global PLUT to use
|
|
- bit 12: Frame is in cel format (DATA_HARDWARE)
|
|
- bit 13: (DATA_COPY aka DATA_SCREEN)
|
|
- bit 14: (DATA_PACKED)
|
|
- bit 15: (X_FLIP)
|
|
4 Hot spot information (definition of (0, 0) in the image):
|
|
- low 2 bytes: x location of hot spot
|
|
- high 2 bytes: y location of hot spot
|
|
4 Image bounds:
|
|
- low 2 bytes: Image width
|
|
- low 2 bytes: Image height
|
|
4 Offset from beginning of the frame description for this
|
|
frame to the beginning of the frame.
|
|
|
|
Frames:
|
|
Then for all frames:
|
|
If DATA_HARDWARE is set in the flags for this frame:
|
|
4 Size of image data
|
|
? .cel image data
|
|
If DATA_PACKED is set in the flags for this frame: (from 3do/imageint.c)
|
|
for every line in the image (bounds.height lines):
|
|
2 number of bytes used to encode this line
|
|
The actual number of bytes is computed like so:
|
|
(number-of-bytes + 2) * 4
|
|
a number of packets of this format:
