  • Comment: 12bit default huffman tables

    I have regenerated the tables in such a way as to build broader "dc" tables. The new generator code is as follows, and the optimal table was generated with a quality of 99. #ifndef generate_universal_tables long total = 0; int has_over_15 = 0; for( i = 0; i < 256; i++ ) { if( freq[i] > 0 ) printf( "freq[%d] = %d\n", i, freq[i] ); total +=...

  • Comment: Add 12bit "renamed" mode

    I have decided not to try and adjust the libjpeg configuration logic. The macro in jmorecfg.h is sufficient. Closing.

  • IO Subsystem Call Safety Fixes

    Some code in jchuff.c and jdhuff.c does not keep next_input_byte and bytes_in_buffer up to date in the source structure. This is not a problem for the read/write implementations provided with libjpeg which seem to assume buffers are always completely consumed, but it is a problem with some implementations of the read/write code that need to deal with libjpeg versions (ie. IPP) that do not...
