MorphOS: Update der Streaming-Bibliothek Reggae
Grzegorz 'Krashan' Kraszewski stellt ein Update seiner MorphOS-Bibliothek für Stream-Medien zur Verfügung. Highlights dieser Version: RLE8-Kompression, Unterstützung für Bilder im BMP-Format inklusive diverser nicht korrekt gespeicherter Abwandlungen, außerdem wurden einige Fehler beseitigt. Die Änderungen im Detail:

netpbm.demuxer 51.5
  • Fixed stupid bug in the recognition routine, initial 'P' was not checked and any byte there was accepted

bmp.demuxer 51.6
  • Added MMA_BlockAlign attribute (stream offset to pixmap data) used by bmp.decoder for workarounds for decoding buggy images
  • Added missing OM_GET and MMM_GetPort entries to the dispatcher
  • Implemented MMM_Seek()
  • Added MMA_StreamPosBytes attribute
  • Recognition routine: if header filesize does not match filesystem filesize, does not set probability to 0. Allows lot of broken images to be accepted

bmp.decoder 51.4
  • Added workaround for buggy savers setting structure size field in the header to 0. 40 bytes is assumed in this case
  • Fixed error reporting in Setup(), result of LoadData() is returned instead of TRUE
  • All memory allocations are now done with MediaAllocVec()
  • Added workaround for images with shortened palette (only NumColors palette entries)
  • Added workaround for palette images with NumColors set to 0
  • Added workaround for images having extra data after bitmap header or palette (forward seek to pixel data offset)
  • Added RLE8 decoder for compressed 8-bit images
