Function Documentation

char* unescape_text_and_overbars	(	char *	text,
		PangoAttrList *	attrs
	)

Definition at line 49 of file o_text.c.

Here is the call graph for this function:

static void calculate_position	(	OBJECT *	object,
		PangoFontMetrics *	font_metrics,
		PangoRectangle	logical_rect,
		PangoRectangle	inked_rect,
		double *	x,
		double *	y
	)		[static]

Note:

Ideally, we would be using just font / logical metrics for vertical alignment, however this way seems to be more backward compatible with the old gschem rendering.

Lower alignment is at the baseline of the bottom text line, whereas middle and upper alignment is based upon the inked extents of the entire text block.
