-
- Look for a file called FLXSPEC.TXT. It's about 30K uncompressed I think.
- The .FLC format is a superset of the .FLI. Here are some parts from it:
- ==========
- The Animator Pro animation file is a good example of a hierarchial
- chunked file structure. The data in an animation file is arranged
- as follows:
-
- animation file:
- optional prefix chunk:
- settings chunk
- cel placement chunk
- frame 1 chunk:
- postage stamp chunk:
- postage stamp data
- color palette chunk
- pixel data chunk
- frame 2 chunk:
- pixel data chunk
- frame 3 chunk:
- color palette chunk
- pixel data chunk
- frame 4 chunk:
- color palette chunk
- ring frame chunk:
- color palette chunk
- pixel data chunk
-
-
- FLC - Animator Pro Flic Files
-
- This is the main animation file format created by Animator Pro.
- The file contains a 128-byte header, followed by an optional
- prefix chunk, followed by one or more frame chunks.
-
- The prefix chunk, if present, contains Animator Pro settings
- information, CEL placement information, and other auxiliary data.
-
- A frame chunk exists for each frame in the animation. In
- addition, a ring frame follows all the animation frames. Each
- frame chunk contains color palette information and/or pixel data.
-
- The ring frame contains delta-compressed information to loop from
- the last frame of the flic back to the first. It can be helpful
- to think of the ring frame as a copy of the first frame,
- compressed in a different way. All flic files will contain a
- ring frame, including a single-frame flic.
-
-
- The FLC file header
-
-
- A FLC file begins with a 128-byte header, described below. All
- lengths and offsets are in bytes. All values stored in the
- header fields are unsigned.
-
- Offset Length Name Description
-
- 0 4 size The size of the entire animation file,
- including this file header.
-
- 4 2 magic File format identifier. Always hex AF12.
-
- 6 2 frames Number of frames in the flic. This
- count does not include the ring frame.
- FLC files have a maximum length of 4000
- frames.
-
- 8 2 width Screen width in pixels.
-
- 10 2 height Screen height in pixels.
-
- 12 2 depth Bits per pixel (always 8).
-
- 14 2 flags Set to hex 0003 after ring frame is
- written and flic header is updated.
- This indicates that the file was properly
- finished and closed.
-
- 16 4 speed Number of milliseconds to delay between
- each frame during playback.
-
- 20 2 reserved Unused word, set to 0.
-
- 22 4 created The MSDOS-formatted date and time of the
- file's creation.
-
- 26 4 creator The serial number of the Animator Pro
- program used to create the file. If the
- file was created by some other program
- using the FlicLib development kit, this
- value is hex 464C4942 ("FLIB").
-
- 30 4 updated The MSDOS-formatted date and time of the
- file's most recent update.
-
- 34 4 updater Indicates who last updated the file. See
- the description of creator.
-
- 38 2 aspectx The x-axis aspect ratio at which the file
- was created.
-
- 40 2 aspecty The y-axis aspect ratio at which the file
- was created. Most often, the x:y aspect ratio
- will be 1:1. A 320x200 flic has a ratio of
- 6:5.
-
- 42 38 reserved Unused space, set to zeroes.
-
- 80 4 oframe1 Offset from the beginning of the file to the
- first animation frame chunk.
-
- 84 4 oframe2 Offset from the beginning of the file to
- the second animation frame chunk. This value
- is used when looping from the ring frame back
- to the second frame during playback.
-
- 88 40 reserved Unused space, set to zeroes.
-
-
- The FLC prefix chunk
-
- An optional prefix chunk may immediately follow the animation
- file header. This chunk is used to store auxiliary data which is
- not directly involved in the animation playback. The prefix
- chunk starts with a 16-byte header (identical in structure to a
- frame header), as follows:
-
- Offset Length Name Description
-
- 0 4 size The size of the prefix chunk, including
- this header and all subordinate chunks
- that follow.
-
- 4 2 type Prefix chunk identifier. Always hex F100.
-
- 6 2 chunks Number of subordinate chunks in the
- prefix chunk.
-
- 8 8 reserved Unused space, set to zeroes.
-
- To determine whether a prefix chunk is present, read the 16-byte
- header following the file header. If the type value is hex F100,
- it's a prefix chunk. If the value is hex F1FA it's the first
- frame chunk, and no prefix chunk exists.
-
- ....
-
- The FLC frame chunks
-
- Frame chunks contain the pixel and color data for the animation.
- A frame chunk may contain multiple subordinate chunks, each
- containing a different type of data for the current frame. Each
- frame chunk starts with a 16-byte header that describes the contents
- of the frame:
-
- Offset Length Name Description
-
- 0 4 size The size of the frame chunk, including this
- header and all subordinate chunks that follow.
-
- 4 2 type Frame chunk identifier. Always hex F1FA.
-
- 6 2 chunks Number of subordinate chunks in the
- frame chunk.
-
- 8 8 reserved Unused space, set to zeroes.
-
-
- Immediately following the frame header are the frame's subordinate
- data chunks. When the chunks count in the frame header is zero, it
- indicates that this frame is identical to the previous frame. This
- implies that no change is made to the screen or color palette, but
- the appropriate delay is still inserted during playback.
-
- Each data chunk within a frame chunk is formatted as follows:
-
- Offset Length Name Description
-
- 0 4 size The size of the chunk, including this header.
-
- 4 2 type Data type identifier.
-
- 6 (size-6) data The color or pixel data.
-
-
- The type values in the chunk headers indicate what type of graphics
- data the chunk contains and which compression method was used to
- encode the data. The following values (and their associated mnemonic
- names) are currently found in frame data chunks:
-
- Value Name Description
-
- 4 FLI_COLOR256 256-level color palette info
- 7 FLI_SS2 Word-oriented delta compression
- 11 FLI_COLOR 64-level color palette info
- 12 FLI_LC Byte-oriented delta compression
- 13 FLI_BLACK Entire frame is color index 0
- 15 FLI_BRUN Byte run length compression
- 16 FLI_COPY No compression
- 18 FLI_PSTAMP Postage stamp sized image
