From 9b299132ef8912910df5a90b1628cc3af1efc54d Mon Sep 17 00:00:00 2001 From: Jon Lund Steffensen Date: Sun, 28 Dec 2014 22:58:54 -0500 Subject: colorramp: Use supplied gamma ramps as initial value This changes colorramp_fill() to base the ramp calculations on the existing values in the supplied tables, instead of basing it on a pure `i/size` value computed on the fly. All gamma adjustment methods are changed to explicitly initialize the ramps to the `i/size` value before calls to colorramp_fill(). --- src/gamma-quartz.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'src/gamma-quartz.c') diff --git a/src/gamma-quartz.c b/src/gamma-quartz.c index f28955f..4eeac4d 100644 --- a/src/gamma-quartz.c +++ b/src/gamma-quartz.c @@ -96,6 +96,14 @@ quartz_set_temperature_for_display(CGDirectDisplayID display, float *gamma_g = &gamma_ramps[1*ramp_size]; float *gamma_b = &gamma_ramps[2*ramp_size]; + /* Initialize gamma ramps to pure state */ + for (int i = 0; i < ramp_size; i++) { + float value = (double)i/ramp_size; + gamma_r[i] = value; + gamma_g[i] = value; + gamma_b[i] = value; + } + colorramp_fill_float(gamma_r, gamma_g, gamma_b, ramp_size, setting); -- cgit v1.2.3-70-g09d2
