Commodore Amiga File Format Handler

Modern software often poorly support older file formats. This package intends to handle many file formats that were native to the antiquated Commodore Amiga machine. This package focuses on file types from the older Amiga operating systems (<= 3.0). It will read and write specific file formats and coerces them into more contemporary data.


AmigaFFH v0.2.0 (Release date: 2019-01-27)

  • Added support for Amiga Workbench Icons (*.info)

  • Added support for the Amiga's system-configuration file

  • Added rasterToHWSprite function

  • Changed 'as.raster' from S4 method to S3 function for more flexibility.

  • 'rasterToBitmap' did not decode continuous bitmaps correctly. This has been fixed. Fortunately the Amiga mostly uses interleaved bitmaps anyway.

  • Added constrains to error distribution in dither method of 'index.colours'. Without these constrains errors could accumulate for certain images and cause undesirable results.

  • Fixed transparency detection in 'index.colour' function

  • Bug-fix in the interpretation of IFF ANIM frames

  • Moved ProTrackR and adfExplorer from 'Depends' to 'Suggests' to avoid circular dependancy

  • Several minor corrections to the manual

AmigaFFH v0.1.2 (Release date: 2018-03-13)

  • A minor fix in the examples to pass CRAN checks.

AmigaFFH v0.1.1 (Release date: 2018-03-10)

First release:

  • This is the first release that supports
    • reading and writing IFF files
    • interpretation of several common data flavours in IFF files
    • interpret hardware sprites
