Hi all, I was hoping someone who has an understanding of text layout might be able to help me. I have written a unit test for ImplLayoutRuns, but I would like to confirm my approach and understanding is correct.
The patch on gerrit can be found here: https://gerrit.libreoffice.org/c/core/+/121204 <https://gerrit.libreoffice.org/c/core/+/121204> In testImplLayoutRuns_AddPos() I add 7 positions. I assume these are glyph positions. What I think I’m doing is to setup a run of 3 non-RTL glyphs, then add a fourth RTL marker glyph, which makes a run of three characters with the RTL maker. I then create a non-RTL glyph position. etc. The code being: ImplLayoutRuns aRuns; aRuns.AddPos(1, false); aRuns.AddPos(2, false); aRuns.AddPos(3, false); aRuns.AddPos(4, true); // add RTL marker glyph aRuns.AddPos(5, false); aRuns.AddPos(6, true); // add RTL marker glyph aRuns.AddPos(7, false); I believe this creates a run of four LTR glyphs, then a run of 2 RTL glyphs, then a run of two LTR glyphs, and final run of 2 RTL glyphs. Can I clarify this is correct? And does each run explicitly include the RTL marker as the first glyph position? The test seems to show this. Chris
