Undefining some of these symbols will produce a smaller but less capable
|
|
library. Note that you can leave certain source files out of the
|
|
compilation/linking process if you've #undef'd the corresponding symbols.
|
|
(You may HAVE to do that if your compiler doesn't like null source files.)}

{ Note: if you selected 12-bit data precision, it is dangerous to turn off
|
|
ENTROPY_OPT_SUPPORTED. The standard Huffman tables are only good for 8-bit
|
|
precision, so jchuff.c normally uses entropy optimization to compute
|
|
usable tables for higher precision. If you don't want to do optimization,
|
|
you'll have to supply different default Huffman tables.
|
|
The exact same statements apply for progressive JPEG: the default tables
|
|
don't work for progressive mode. (This may get fixed, however.) }
