gtk-text-iter-visible-slice (start end)

start -- a gtk-text-iter instance with the start of a range
end -- a gtk-text-iter intance with the end of a range

A string with a slice of text from the text buffer.

Like the function gtk-text-iter-slice, but invisible text is not included.

Invisible text is usually invisible because a gtk-text-tag object with the "invisible" attribute turned on has been applied to it.
