Function Documentation

__attribute__()

static __attribute__ ( (always_inline)  )

inlinestatic

Interpolate two keyed correction matrices entry-wise.

Build the keyed full transform matrix for one scene luminance.

The transforms are stored in transposed padded form so they can be fed directly to the SIMD matrix-vector multiply. Interpolating them entry-wise in that storage remains equivalent to interpolating the underlying 3x3 matrix.

Parameters

[in]	from	Source keyed correction matrix in transposed padded form.
[in]	to	Destination keyed correction matrix in transposed padded form.
[in]	alpha	Interpolation factor from source to destination.
[out]	interpolated	Interpolated matrix in the same transposed padded form.

Inside the [dark ; bright] segment, the module linearly interpolates between the two user transforms. Outside that segment, the nearest transform fades linearly back to identity over one segment length so the correction tapers out instead of clipping.

Parameters

[in]	luminance	Current pixel scene luminance in XYZ Y.
[in]	d	Precomputed module state for the current pipe.
[out]	matrix	Keyed full transform matrix in transposed padded form.

References row.

Refresh cached GUI colors after the darkroom pipe has converged.

Slider backgrounds and the preview gradient depend on the current work and display profiles. Those profiles may be unavailable during the very first draw after the module widget is created, so we listen to pipe completion and rebuild the cached surfaces as soon as the pipe is ready.

Parameters

[in]	instance	Unused signal emitter.
[in]	user_data	Current module instance.

Render the cached split-toning preview as a simple keyed gradient.

Parameters

[in]	self	Current module instance.
[in,out]	surface	Cached Cairo image surface to repaint.

Repaint every slider background for one split-toning keyframe.

Parameters

[in]	self	Current module instance.
[in]	point	Shadow or highlight keyframe being edited.

Set a brightness keyframe from the average luminance of a picked area.

The picker samples the current module buffer in working RGB. We convert that average RGB to scene luminance Y in the active working profile, then map the result to EV so each anchor can be snapped directly to image content.

Parameters

[in]	self	Current module instance.
[in]	picker	Picker-enabled brightness slider that requested the sample.
[in]	pipe	Active pixelpipe that produced the sampled buffer.
