◆ ED_annotation_data_get_active()

bGPdata * ED_annotation_data_get_active ( const bContext * C )

Get the active Grease Pencil data-block

Note: This is the original (#G.main) copy of the data-block, stored in files. Do not use for reading evaluated copies of GP Objects data.

tGPspoint * ED_gpencil_sbuffer_ensure	(	tGPspoint *	buffer_array,

◆ ED_gpencil_stroke_can_use_direct()

bool ED_gpencil_stroke_can_use_direct	(	const ScrArea *	area,
		const bGPDstroke *	gps )

Check whether given stroke can be edited given the supplied context. TODO: do we need additional flags for screen-space vs data-space?.

◆ gpencil_point_to_xy()

void gpencil_point_to_xy	(	const GP_SpaceConversion *	gsc,
		const bGPDstroke *	gps,
		const bGPDspoint *	pt,
		int *	r_x,
		int *	r_y )

Convert a Grease Pencil coordinate (i.e. can be 2D or 3D) to screen-space (2D)

Parameters

[out]	r_x	The screen-space x-coordinate of the point
[out]	r_y	The screen-space y-coordinate of the point

Warning: This assumes that the caller has already checked whether the stroke in question can be drawn.
