- Short: IFF ANIM DataType V1.11
- Author: GISBURN@w-specht.rhein-ruhr.de (Roland Mainz)
- Uploader: GISBURN@w-specht.rhein-ruhr.de (Roland Mainz)
- Type: util/dtype
- Replaces: util/dtype/animdtc0110.LhA
-
- IFF ANIM DataType, a replacement for (little bit) buggy CBM anim.datatype.
- animation.datatype subclass.
-
- Shareware !
-
- Starting with V1.8, anim.datatype is shareware. See "anim.datatype.doc/MAIN"
- for details
-
- Features are:
- - Can save it's local format.
- anim.datatype supports DTM_WRITE for it's local format, e.g you
- can save animations in IFF ANIM using this datatype.
- Supports currently IFF ANIM-3 as output format, other formats
- are on the way.
- Converters like "DTConvert" are now able to write IFF ANIM using this
- datatype :-)
-
- - Supports sound.
- Any sound (loaded with a sound.datatype subclass) can be attached to the
- animation.
-
- If you want, you can read-out this animation+sound as an IFF FILM stream
- (using DumpDTAnim (Aminet:gfx/conv/DumpDTAnim#?.LhA)) and make a
- playback using film.datatype.
-
- - Per-frame-colormaps (e.g. palatte change per frame). Using DBufDTAnim
- >= v1.2 (Aminet:gfx/show/DBufDTAnim) or animation.datatype V41, you can use
- this feature.
-
- - Supports all (currently) defined ANIM compression modes:
- - ANIM-0 ILBM BODY
- - ANIM-1 ILBM XOR (disabled, no test files)
- - ANIM-2 Long Delta mode
- - ANIM-3 Short Delta mode
- - ANIM-4 General Delta mode (disabled, no test files)
- - ANIM-5 Byte Delta mode
- - ANIM-6 Stereo Byte Delta mode
- - ANIM-7 Anim-5 compression using LONG/WORD data
- - ANIM-8 Anim-5 compression using LONG/WORD data
- - ANIM-J Eric Grahams compression format
-
- - Compression modes can be mixed in any way (e.g. ANIM-5 with ANIM-J etc.).
-
- - Interleave counts can have any value (not limited to 1 or 2 frames back),
- maybe 255.
-
- - Should be safer than the CBM version. Includes stack checking code and
- many asserts to avoid crashes.
-
- - Random frame access (even to deltas).
-
- - Supports clipboard as input.
-
- - Dynamic loading of frames (disk-based) or caching the whole anim in memory.
-
- - Preference file with various options and per project settings like
- - Viewmode ID
- - Frames Per Second Rate
- - VERBOSE option which shows the internal structure of the animation stream
- (used compression modes; animation dimensions and other attributes).
- - Sound attachment with
- - Volume control
-
- - Matches the "DataTypes" proposal.
-
- Future versions will implement:
- - Frame skipping (by compression type and/or by frame number).
-
- - Color cycling in an animation.
-
- Changes since last release (V1.10):
-
- V1.11
- - Recompiled with SAS/C 6.58. May fix some mc68060 related
- problems.
-
- - Found the longstanding bug that animation.datatype V40.7
- didn't free some frames. Reason is that ADTM_LOADFRAME
- may be used like "realloc". Now alf_UserData is checked;
- any given frame will be freed (ADTM_UNLOADFRAME).
- Fixed.
-
- - ADTM_UNLOADFRAME now clears alf_UserData to indicate that the
- frame has been freed.
-
- - Now supports anims deeper than 8 planes, but a colormap
- (e.g. a CMAP chunk) is still expected.
-
- - Fixed the bug that a free of the current frame caused an frame
- to be not freed. (The idea was to hold the current frame for
- following delta accesses; this has been replaced by the idea
- of the "posted free").
-
- - Implemented the idea of a "posted free". For delta accesses,
- it's not very usefull to free the frame when the next frame
- needs it for it's delta access. Therefore, the anim.datatype
- now manages a "free list", where the free of the previous
- and the previous-previous frame will be posted until
- it is really not longer in use.
-
- - Fixed a bug in the LOADALL mode that the wrong previous
- frame was used (due a change in V1.10).
-
- - The single framenodes now caches a pointer to their previous
- frame. This should speed up loading a little bit.
-
- - If an animation has dynamic timing and the superclass
- (animation.datatype) has the ADTA_AdaptiveFPS flag set,
- the playback speed now defaults to 60 fps.
-
- - Saved an AllocVecPooled in ADTM_LOADFRAME by merging multiple
- delta buffer allocations to one allocation (which can hold the
- largest delta).
-
- - The stack swapping code now allocates it's memory without
- the MEMF_CLEAR flags, which should speed up things.
-
- - Removed BestModeIDA code, because animation.datatype does
- the same.
-
- - The options setting for DPaint brush compatibility patch
- worked wrong (the order was wrong). Now the options
- work as described.
- Fixed.
-
- - Fixed a bug in the encoder that the last color of a dynamic
- pallete as not copied (GetRGB32 got numcolors - 1 instead
- of numcolors).
- Fixed.
