Apple IIgs GSLA Player
|
||||
|
||||
Example of a GS LZB Animation Player
|
||||
|
||||
New Apple IIgs Animation file format
|
||||
GS LZ Byte Compressed Animation
|
||||
Why? When there are so many image formats would we need another one? It’s
|
||||
because $C2/Paintworks animation format is just terribly inefficient.
|
||||
|
||||
Care is taken in the encoder, to make sure the 65816 does not have to cross bank
|
||||
boundaries during any copy. This is so we can use the MVN instruction, and so
|
||||
we can reduce the number of bank checks in the code. Some bank checks will be
|
||||
required, because we are dealing with data sizes that exceed 64KB at times.
|
||||
|
||||
We will have an opcode, that says “source data bank has changed”
|
||||
|
||||
Goals include a good balance between file size, and playback performance
|
||||
(since one often makes a trade off with the other).
|
||||
|
||||
The file is defined as a byte stream.
|
||||
|
||||
I will attempt to define the format as
|
||||
|
||||
file-offset: the thing that is at the offset
|
||||
|
||||
Header of the File is 20 bytes as follows
|
||||
|
||||
File Offset Data Commentary
|
||||
------------------------------------------------------------------
|
||||
0 0x47 ; ‘G’ Graphics
|
||||
1 0x53 ; ‘S’
|
||||
2 0x4C ; ‘L’ LZB
|
||||
3 0x41 ; ‘A’ Animation
|
||||
|
||||
; File Length, is the total length of the file
|
||||
4 FileLengthLow ; Low byte, 32-bit file length
|
||||
5 LengthLowHigh ; High byte of low word
|
||||
6 LengthHighLow ; Low byte, of high word
|
||||
7 LengthHighHigh ; High Byte, of high word
|
||||
|
||||
; 16 bit word with version #
|
||||
8 VL ; Version # of the file format, currently only version 0
|
||||
9 VH ; Version High Byte
|
||||
; %RVVV_VVVV_VVVV_VVVV
|
||||
; V is a version #, 0 for now
|
||||
; R is the MSB, R = 0 no ring frame
|
||||
; R = 1, there is a ring frame
|
||||
; A Ring Frame is a frame that will delta from the last
|
||||
; frame of the animation, back to the first, for smoother
|
||||
; looping , If a ring frame exists, it’s also in the
|
||||
; frame count
|
||||
|
||||
// next is a word, width in bytes (only 160 for now)
|
||||
0xA WL ; Display Width in bytes low byte
|
||||
0xB WH ; Display Width in bytes high byte
|
||||
// next is a word, height (likely 200 for now, in tiled mode a multiple of 16)
|
||||
0xC HL ; Display Height in bytes, low byte
|
||||
0xD HH ; Display Height in bytes, high byte
|
||||
// 2 bytes, Frame Size in Bytes, since a “Frame” may contain more than just the
|
||||
// width * height, worth of pixels, for now this is $8000, or 32768
|
||||
0xE FBL ; Frame Buffer Length Low
|
||||
0xF FBH ; Frame Buffer Length High
|
||||
|
||||
// 4 byte, 32-bit, Frame Count (includes total frame count, so if there is a
|
||||
// ring frame, this is included in the total)
|
||||
0x10 FrameCountLow
|
||||
0x11 FrameCountLowHigh
|
||||
0x12 FrameCountHighLow
|
||||
0x13 FrameCountHigh
|
||||
|
||||
|
||||
After this comes AIFF style chunks of data, basically a 4 byte chunk name,
|
||||
followed by a 4 byte length (inclusive of the chunk size). The idea is that
|
||||
you can skip chunks you don’t understand.
|
||||
|
||||
File Offset:
|
||||
0x14 First Chunk (followed by more Chunks, until end of file)
|
||||
|
||||
Chunk Definitions
|
||||
Name: ‘INIT’ - Initial Frame Chunk, this is the data used to first
|
||||
initialize the playback buffer
|
||||
0: 0x49 ; ‘I’
|
||||
1: 0x4E ; ‘N’
|
||||
2: 0x49 ; ‘I’
|
||||
3: 0x54 ; ‘T’
|
||||
// 32 bit long, length, little endian, including the 8 byte header
|
||||
4: length low low
|
||||
5: length low high
|
||||
6: length high low
|
||||
7: length high high
|
||||
|
||||
8: This is a single frame of data, that decodes/decompresses into frame sized
|
||||
bytes (right now 0x8000)
|
||||
This data stream includes, an end of animation opcode, so that the normal
|
||||
animation decompressor, can be called on this data, and it will emit the initial
|
||||
frame onto the screen
|
||||
|
||||
Name: ‘ANIM’ - Frames
|
||||
0: 0x41 ‘A’
|
||||
1: 0x4E ‘N’
|
||||
2: 0x49 ‘I’
|
||||
3: 0x4D ‘M’
|
||||
// 32 bit long, length, little endian, including chunk header
|
||||
4: length low low
|
||||
5: length low high
|
||||
6: length high low
|
||||
7: length high high
|
||||
|
||||
// This is followed by the frames, with the intention of decompressing them at
|
||||
// 60FPS, which is why no play speed is included, if you need a play-rate slower
|
||||
// than this, blank frame’s should be inserted into the animation data
|
||||
|
||||
// Every attempt is made to delta encode the image, meaning we just encode
|
||||
// information about what changed each frame. We attempt to make the size
|
||||
// efficient by supporting dictionary copies (where the dictionary is made up of
|
||||
// existing pixels in the frame buffer).
|
||||
|
||||
Command Word, encoded low-high, what the bits mean:
|
||||
|
||||
// xxx_xxxx_xxxx_xxx is the number of bytes 1-16384 to follow (0 == 1 byte)
|
||||
|
||||
%0xxx_xxxx_xxxx_xxx0 - Copy Bytes - straight copy bytes
|
||||
%1xxx_xxxx_xxxx_xxx1 - Skip Bytes - skip bytes / move the cursor
|
||||
%1xxx_xxxx_xxxx_xxx0 - Dictionary Copy Bytes from frame buffer to frame buffer
|
||||
|
||||
%0000_0000_0000_0001- Source Skip -> Source pointer skips to next bank of data
|
||||
%0000_0000_0000_0011- End of Frame - end of frame
|
||||
%0000_0000_0000_0111- End of Animation / End of File / no more frames
|
||||
|
||||
// other remaining codes, are reserved for future expansion
