Function pango-layout-line-x-ranges

Lambda List

pango-layout-line-x-ranges (line start-index end-index ranges n-ranges)

Arguments

iter -- a pango-layout-iter instance
start-index -- an integer with the 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.
end-index -- an integer with the 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.

Return Value

ranges -- a pointer to an array of ranges. The array will be of length 2*n_ranges, with each range starting at (*ranges)[2*n] and of width (*ranges)[2*n + 1] - (*ranges)[2*n]. This array must be freed with g-free. The coordinates are relative to the layout and are in Pango units
n-ranges -- The number of ranges stored in ranges.

Details

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.
