pangoLayoutLineGetXRanges: pangoLayoutLineGetXRanges

Description

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.

Usage

pangoLayoutLineGetXRanges(object, start.index, end.index)

Arguments

object

start.index

end.index

[integer] 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.

Value

A list containing the following elements:

ranges

[integer] out): (array length=n_ranges): (transfer=full. out): (array length=n_ranges): (transfer=full.

n.ranges
