702 header. In earlier versions png_set_gamma() existed but behaved incorrectly if

756 encoding if it has no gAMA chunk and if png_set_gamma() has not been called
766 encoding will be overridden if png_set_gamma() is called - the results may be
824 png_set_gamma(png_ptr, screen_gamma, 1.0/screen_gamma);
827 The screen_gamma value is the same as the argument to png_set_gamma; however,
830 png_set_gamma. If you need different defaults call png_set_gamma() before
901 If you call png_set_gamma() after png_set_alpha_mode() you
1051 is easier than achieving the same effect with png_set_gamma. You must use
1207 provided by an earlier call to png_set_gamma or png_set_alpha_mode.
1978 If you didn't call png_set_gamma() before reading the file header, for example
1984 supported then you can certainly do png_set_gamma() before reading the PNG
1993 png_set_gamma(png_ptr, screen_gamma, file_gamma);
1996 png_set_gamma(png_ptr, screen_gamma, 0.45455);
