_record_point_area()

static gboolean _record_point_area ( dt_iop_color_picker_t *  self )

static

Synchronize one picker cached geometry with the primary sample.

The active picker keeps a copy of the sample point/box so reopening it restores the previous GUI geometry. This function only mirrors the current primary sample into that cached geometry and reports whether the coordinates changed since the previous sampling pass.

It does not consume self->update_pending. That flag is the same update logic seen from the non-geometric side: first activation and colorspace changes request one callback even if the picker geometry itself did not move.

dt_iop_color_picker_is_active_module()

gboolean dt_iop_color_picker_is_active_module

(

const dt_iop_module_t *

module

)

Tell whether one module currently owns the active darkroom picker.

Module code often needs to know whether a GUI callback is running for the module that currently captures picker updates. That ownership lives under dt_develop_t::color_picker, so callers should query it through this API instead of open-coding the develop-state test at each call site.

Parameters

module

Candidate module.

Returns

TRUE when the picker manager is enabled and the active picker belongs to module.
