Methods / Constructors
Method / Constructor		Defined By
	new Pango.LayoutLine () Create a new Pango.LayoutLine Create a new Pango.LayoutLine
	get_extents () : Object Computes the logical and ink extents of a layout line. Computes the logical and ink extents of a layout line. See pango_font_get_glyph_extents() for details about the interpretation of the rectangles. Returns: ink_rect: Pango.Rectangle logical_rect: Pango.Rectangle	Pango.LayoutLine
	get_pixel_extents () : Object Computes the logical and ink extents of layout_line in device units. Computes the logical and ink extents of layout_line in device units. This function just calls pango_layout_line_get_extents() followed by two pango_extents_to_pixels() calls, rounding ink_rect and logical_rect such that the rounded rectangles fully contain the unrounded one (that is, passes them as first argument to pango_extents_to_pixels()). Returns: ink_rect: Pango.Rectangle logical_rect: Pango.Rectangle	Pango.LayoutLine
	get_x_ranges (gint32 *start_index, gint32 end_index) : Object Gets a list of visual ranges corresponding to a given logical range. Gets a list of visual ranges corresponding to a given logical range. This list is not necessarily minimal - there may be consecutive ranges which are adjacent. The ranges will be sorted from left to right. The ranges are with respect to the left edge of the entire layout, not with respect to the line. Parameters: gint32 start_index* Required (not null) Start byte index of the logical range. If this value is less than the start index for the line, then the first range will extend all the way to the leading edge of the layout. Otherwise it will start at the leading edge of the first character. gint32 end_index Required (not null) Ending byte index of the logical range. If this value is greater than the end index for the line, then the last range will extend all the way to the trailing edge of the layout. Otherwise, it will end at the trailing edge of the last character. Returns: ranges: Array n_ranges: gint32	Pango.LayoutLine
	index_to_x (gint32 *index_, gboolean trailing) : gint32 Converts an index within a line to a X position. Converts an index within a line to a X position. Parameters: gint32 index_* Required (not null) byte offset of a grapheme within the layout gboolean trailing Required (not null) an integer indicating the edge of the grapheme to retrieve the position of. If > 0, the trailing edge of the grapheme, if 0, the leading of the grapheme. Returns: gint32	Pango.LayoutLine
	x_to_index (gint32 *x_pos, Object out_values) : gboolean Converts from x offset to the byte index of the corresponding character within the text of the layout. Converts from x offset to the byte index of the corresponding character within the text of the layout. If x_pos* is outside the line, in the line. This determination is based on the resolved direction of the paragraph; for example, if the resolved direction is right-to-left, then an X position to the right of the line (after it) results in 0 being stored in index_ and trailing. An X position to the left of the line results in index_ pointing to the (logical) last grapheme in the line and trailing being set to the number of characters in that grapheme. The reverse is true for a left-to-right line. Parameters: gint32 x_pos Required (not null) the X offset (in Pango units) from the left edge of the line. Object out_values gint32 index_ gint32 trailing Returns: gboolean FALSE if x_pos was outside the line, TRUE if inside	Pango.LayoutLine
