- REQUIREMENTS
- - Any Amiga® (compatible) computer with at least OS3.0.
- - 68020+ cpu
- - cybergraphics v2/3, picasso96, cyberprobench or OCS/ECS/AGA
- - any picture.datatype (v43 recommend, p96 version works
- without gfxboard)
-
-
- DESCRIPTION
- ilbm.datatype v44 allows you to display ham and ehb pictures on a
- non-native (eg. p96/cgfx) screen in correct colors. Even if you
- don't have a gfx-board you'll be able to view 24bit iff images,
- when picture.datatype v43 (p96 version) is installed.
- NOTE TO CGFX USERS: Due to some internal changes you have to turn
- on the PLANES2FAST option for maximum speed.
-
-
- INSTALLATION
- Just 'Copy ilbm.datatype TO SYS:classes/datatypes/'.
-
-
- KNOWN PROBLEMS
- - DOpus Mangellan and 24bit/ham images
- According to the docs of DOpus 5.65, DOpus has some problems to
- display 24bit images under certain circumstances. This is not a bug
- of the datatype! (thanks to Dennis Barret for the error report)
- pre 5.65 releases work fine.

- HISTORY
- 44.0 1st upload: first public release
- 44.0 2nd upload: reworked the doc file
- 44.1 a few optimiziations, skips masking planes now,
- added KNOWN PROBLEMS section to the doc
- 44.2 fixed a bug which made some programs (ex. MUI)
- to display garbage when using a 24bit/ham image on
- a screen deeper than 8bit.
- 44.3 bug fix: enforcer hit when library was expunged
- (thanks to Magnus Holmgren for the error report)
- 44.4 bug fix: iff24 images with masking weren't correctly
- decoded (thanks to Steve Cutting for the error report)
- 44.5 cleaned-up the code a little bit, special version which
- supports planar to chunky hardware
- 44.6 removed p2c version (slower than normal one). supports
- b/w and greyscale pictures now (no cmap, mainly used by
- PageStream). Didn't set transparent color for images
- with transparent masking (hope that is fixed now).
- 44.7 doesn't require cgfx/p96 and pictdtv43 any longer
- 44.8 aspect ratio wasn't set
- 44.9 works with ProBench now
- 44.10 compiled with gcc (made some internal changes necessary),
- datatype is now some bytes smaller and probably a bit faster
- when decoding <= 8bit images.
