21 persson 1627
22 persson 1678 * src/RIFF.cpp, src/RIFF.h:
23     - bugfix: saving to the same file after the file size had been

386    
387     * general changes:
388     - various big endian specific corrections
389     (successfully tested now on PPC)
390     - minor adjustments to avoid compile errors on some systems
391     (using now pow() instead of powl() and --pedantic g++ compiler switch)
392     - libtoolized the library
393     - added man pages for the command line tools
394     (gigextract, gigdump, dlsdump, rifftree)

397     - fixed bug in decompression algorithm which caused it not to detect
398     the end of a stream
399     - added method GetVelocityAttenuation() to class 'DimensionRegion' which
400     takes the MIDI key velocity value as an argument and returns the
401     appropriate volume factor (0.0 ... 1.0) for the sample to be played
402     back, the velocity curve transformation functions used for this are
403     only an approximation so far
404     - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
405     'Sample::LoopSize' which reflected wrong values
406     - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
407     measured in sample points instead of byte offset
408     - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
409     'Sample::FineTune'
410     - added class attribute 'Sample::LoopSize'
411     - added method GetInstrument(uint index) to class 'File'
412     - added ReadAndLoop() method to class 'Sample' which is an extension to
413     the normal Read() method to honor the sample's looping information
414     while streaming from disk
415     - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
416     'eg2_ctrl_t': replaced this huge enumeration by a structure which
417     reflects the MIDI controller number in case of an ordinary control
418     change controller (this saves a huge switch-case block in the
419     application of the library user)
420     - renamed following attributes in class 'DimensionRegion':
421     'AttenuationContol' -> 'AttenuationController',
422     'InvertAttenuationControl' -> 'InvertAttenuationController',
423     'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
424     - minor fix in API documentation for method GetVelocityAttenuation() in
425     class 'DimensionRegion'
426    
427     * src/RIFF.cpp, src/RIFF.h:
428     - added additional API documentation
429     - minor fix in Chunk::Read() method (only a minor efficiency issue)
430    
431     * src/gigdump.cpp:
432     - added printout of samples' looping informations
