#  tests/pngstest gamma alpha
 | 
						|
#
 | 
						|
# Run ./pngstest on the PNG files in $srcdir/contrib/testpngs which have the
 | 
						|
# given gamma and opacity:
 | 
						|
#
 | 
						|
#  gamma: one of; linear, 1.8, sRGB, none.
 | 
						|
#  alpha: one of; opaque, tRNS, alpha, none.  'none' is equivalent to !alpha
 | 
						|
#
 | 
						|
# NOTE: the temporary files pngstest generates have the base name gamma-alpha to
 | 
						|
# avoid issues with make -j
 |
