# bmp2png/cfg - "Build" settings for package

#---------------------------------------------------------------------

[technotes]

# 1. This package  requires a version of  "libpng"  that  provides the
# legacy function "png_read_data".

#---------------------------------------------------------------------

# 2. This package  installs  a modified  version of  Miyasaka Masaru's
# "bmp2png" program.  Specifically, it puts  two  wrappers  around the
# original  program.  One wrapper is named "bmp2png" and  the other is
# named "bmp2png-fast".

# The "bmp2png" wrappers accept  BMP-file arguments (as before).  How-
# ever,  at the present time,  they ignore everything else  (including
# option switches).

# The specified BMP input files are converted to PNG output files  (as
# before). However, the "bmp2png" wrapper maximally-compresses the PNG
# files.  Specifically,  it passes "-9" to the original program,  then
# runs  PNG output files through  an external  PNG compression utility
# named "optipng".

# The "bmp2png" wrapper also preserves  timestamps.  I.e.,  PNG output
# files have the same timestamps as the corresponding BMP input files.

# The PNG output files are stored in the  same directories  as the BMP
# input files (as before).

# The  "bmp2png-fast" wrapper is  almost  identical  to the  "bmp2png"
# wrapper, but it doesn't run "optipng". Therefore, it runs faster but
# produces larger output files.

#---------------------------------------------------------------------

# 3. This package  also installs Miyasaka Masaru's  "png2bmp" program.
# Note: Presently, no wrapper is used for "png2bmp".
