dev	Develop context.
imgid	Image id.

Returns: TRUE if this is a newly-initialized history, FALSE otherwise.

	)

Merge a single module instance into a destination history.

Creates or reuses a destination module instance and copies its parameters. This does not resync the pipeline or pop history; callers should batch multiple merges and resync once.

Parameters

dev_dest	Destination develop context.
dev_src	Source develop context (may be NULL to skip mask copy).
mod_src	Source module instance.

Returns: 1 on success, 0 on failure.

◆ dt_history_module_skip_copy()

gboolean dt_history_module_skip_copy ( const int flags )

Determine whether a module should be skipped during history copy.

Evaluates module flags such as deprecated/unsafe/hidden.

Parameters

flags Module flags.

Returns: TRUE if module should be skipped, FALSE otherwise.
