Output values is not bitwise the same as the LUT-based

a3dd3d0f9e avoid installing example_util.h
older versions of automake (1.9) it seems would install the headers
regardless of the fact that the library was marked noinst_

this change follows some of the header guidance found here:

69e2590642 Merge "Tune Lossless compression for lower qualities." 2013-03-12 22:08:29 -07:00
Vikas Arora
0478b5d214 Tune Lossless compression for lower qualities.
This is required for WebP lossy+Alpha images, where Alpha channel is taking
60-70% of the compression (CPU) cycles.

Also evaluated on 1000 PNG corpus and overall compression speed
is 15-40% better for lossy (PNG+Alpha) compression.
The pure lossless compression numbers are almost same (or little
better) with this change.

5a21d96741 Merge "1.5x-2x faster encoding for method 3 and up" 2013-03-11 17:14:18 -07:00
skal
9bfbdd144f 1.5x-2x faster encoding for method 3 and up
using token-buffer (that is: slightly more memory. O(output_size))

This change is ON by default. To return to previous behaviour, use
'cwebp -low_memory' or set config.low_memory to true.

Side-effect of this new mode: it forces 1 partition only (which was
default anyway), and makes some statistics about the bitstream
no longer available. cwebp will no longer report 'intra4-coeffs', etc.

This mode also doesn't work (yet) with multi-pass, and -low_memory
is currently forced for multi-pass.

also: reversed the flag: USE_TOKEN_BUFFER -> DISABLE_TOKEN_BUFFER
also: fixed the kAverageBytesPerMB estimate
