Methods / Constructors
Method / Constructor		Defined By
	new Pango.LayoutLine () Create a new Pango.LayoutLine Create a new Pango.LayoutLine
	get_extents (Rectangle *ink_rect, Rectangle logical_rect) : none 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. Parameters: Pango.Rectangle ink_rect* Required (not null) as drawn, or NULL Pango.Rectangle logical_rect Required (not null) string, or NULL Returns: none	Pango.LayoutLine
	get_pixel_extents (Rectangle *ink_rect, Rectangle logical_rect) : none 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()). Parameters: Pango.Rectangle ink_rect Required (not null) as drawn, or NULL Pango.Rectangle logical_rect Required (not null) string, or NULL Returns: none	Pango.LayoutLine
	get_x_ranges (Number *start_index, Number 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: Number start_index* Required (not null) 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. Number end_index Required (not null) 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: Number	Pango.LayoutLine
	index_to_x (Number *index_, Boolean trailing, Number x_pos) : none Converts an index within a line to a X position. Converts an index within a line to a X position. Parameters: Number index_* Required (not null) Boolean trailing Required (not null) the position of. If > 0, the trailing edge of the grapheme, if 0, the leading of the grapheme. Number x_pos Required (not null) Returns: none	Pango.LayoutLine
	x_to_index (Number *x_pos, Object out_values) : Boolean 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: Number x_pos Required (not null) from the left edge of the line. Object out_values Number index_ Number trailing Returns: Boolean	Pango.LayoutLine
