# write.dfa # Build time configuration of libpng # # Author: John Bowler # Copyright: (c) John Bowler, 2013 # Usage rights: # To the extent possible under law, the author has waived all copyright and # related or neighboring rights to this work. This work is published from: # United States. # # Build libpng with no read support and minimal write support. # everything = off # Switch on the write code - this makes a minimalist encoder option WRITE on # Choose fixed or floating point APIs and arithmetic. The choices are # independent but normally they will match. It is typically better to use the # floating point if you have floating point hardware. If you don't know, or # (perhaps) to make libpng smaller used fixed point throughout. #Fixed point: #option FIXED_POINT on #option FLOATING_ARITHMETIC off #Floating point: option FLOATING_POINT on option FLOATING_ARITHMETIC on # Basic error handling, IO and user memory support. The latter allows the # application program to provide its own implementations of 'malloc' and 'free'. option SETJMP on option STDIO on option USER_MEM on # Everything else is optional. Unlike the read code in libpng the write code # does not need to deal with arbitrary formats, so only add support for things # you really do write! For example you might only write sRGB images, sometimes # with transparency and never write 16 bit images, so: option WRITE_sRGB on option WRITE_tRNS on #option WRITE_16BIT off (this is the default with 'everything = off')
