dt_histogram_scope_buf_t

typedef struct dt_histogram_scope_buf_t dt_histogram_scope_buf_t

A scope backbuffer, reoriented to match the darkroom view when it comes from a pre-flip pipeline stage. Every scope binning function should read data/width/height from here instead of the raw backbuf/cache pointer – for already-view-oriented stages, or an identity orientation, this is a plain passthrough (no copy, no allocation).

Only "initialscale" (the "Raw image" scope stage) lives upstream of the flip module in iop_order; "colorout" and "gamma" already sit downstream of it, i.e. already in the same orientation the darkroom view shows – so those are always a passthrough regardless of the image's own orientation.

Retry a scope render after its source cacheline has been published.

The first render attempt stores the current backbuffer hash in the Cairo cache before the non-blocking GUI cache probe can report a miss. Invalidate that rendered-state cache here so the wait-manager wake-up retries pixel binning instead of treating the incomplete surface as current.

Check that the selected histogram backbuffer belongs to the current preview graph.

Global histogram stages are independent published cachelines. Their CACHELINE_READY signal is raised while the preview pipeline is still processing, before its final backbuffer becomes valid. Requiring that final backbuffer here would discard the only refresh scheduled for the newly published histogram stage after a module parameter change.

Matching the stage hash against the current piece is sufficient: the histogram backbuffer owns its cache reference, and the piece hash proves that its pixels and geometry belong to the synchronized preview graph.

The scope content is rendered first because the label describes the final visible state. The theme owns the text color through graph_scope_restricted, while the module keeps the Cairo operator explicit because it controls how the label is composited with the already-rendered graph pixels.

_resolve_backbuf_sampling_source()

static

Resolve the live preview-stage geometry behind one global histogram backbuffer.

The global histogram stores only the published cache hash, width, and height. For color-picker sampling we also need the live ROI, colorspace, and backtransform cut in the current preview graph so the picker point drawn on the final image is mapped back to the selected histogram stage before sampling pixels.

We reopen the stage by operation name because the current preview graph is authoritative once the preview run completed. The published backbuffer hash must still match that live graph, otherwise we are looking at stale geometry and should not trust it.

Parameters

op	Histogram stage operation name.
backbuf	Published histogram backbuffer for op.
roi	Output ROI of the sampled stage buffer.
dsc	Buffer descriptor of the sampled stage buffer.
iop_order	IOP order at which to stop the backtransform.
direction	Inclusive/exclusive transform cut matching the sampled stage buffer.

Returns

TRUE when the live preview graph still matches the published backbuffer, FALSE otherwise.

Apply one vertical size request from the generic Bauhaus resize handle.

The Bauhaus widget owns pointer tracking and sends requested heights here. The histogram owns the scope widget, the window-relative clamp, and persistence, so these side effects remain explicit in the module that owns the resized surface.
