Re: Is pango_break suitable for breaking text into lines?

Thank you for your anwser. I admit that I should calculate it myself, but I still do not know where can I get width of a cluster. BTW, what is a "cluster"? Pango manual does not have a glossary. Maybe I should get data from "pango_shape" and "PangoGlyphString" and "PangoGlyphInfo" and "PangoGlyphGeometry"? There are no glyph extents in "PangoGlyphGeometry", so I am stuck again.

Is "pango_break" suitable for breaking text into lines such that each line has
width less then some number? I know I can achieve this with "PangoLayout" and
"pango_layout_set_width", but can "pango_break" do the same? I can not find a
function which sets line width.

As "PangoLayout" is considered "high-level" and "pango_break" is considered
"low-level", I guess that the low-level API should have this feature too. More
common case is when a low-level API has features that a high-level API does not.

You get the output of pango_break, then walk over the clusters yourself and
decide where you want to break.  That's the difference between highlevel and
lowlevel: using the lowlevel API you need to do some work yourself.
